Triggering a servo using an HC-SR04 distance sensor and an Arduino | #Coding #Maker #MakerED #MakerSpaces

Triggering a servo using an HC-SR04 distance sensor and an Arduino | #Coding #Maker #MakerED #MakerSpaces | 21st Century Learning and Teaching | Scoop.it

Much like my previous Ultrasonic Sensor tutorial, the Young Makers need to be able to trigger an event when someone walks past a display. In their case, they need to make an element on a poster move when someone walks within three feet of the ultrasonic sensor.

Le désir d’apprendre : un oublié de l’école… - Ecole changer de cap! 

Le désir d’apprendre : un oublié de l’école… - Ecole changer de cap!  | 21st Century Learning and Teaching | Scoop.it

Motiver ?


Depuis la fin du XIXème siècle, de nombreux de pédagogues ont avancé des propositions pour donner vie et force au désir d’apprendre. Alfred Binet, pédagogue et psychologue français, plus connu pour ses tests, écrivait par exemple en 1902 dans son livre « Les idées modernes sur les enfants » :

 : « Au lieu de lui expliquer des idées, il vaut mieux les lui faire trouver ; au lieu de lui donner des ordres, il vaut mieux lui laisser la spontanéité de ses actes, et n’intervenir que pour contrôler ». Il ajoutait plus loin : « Entrez dans une classe ; si vous voyez les élèves immobiles, écoutant sans peine un maître agité qui pérore dans sa chaire, ou encore vous voyez ces enfants, copier, écrire le cours que le maître leur dicte, dites-vous que c’est de la mauvaise pédagogie. J’aime mieux une classe où je verrais des enfants moins silencieux, plus bruyants mais occupés à faire le travail le plus modeste, pourvu que ce soit un travail où ils mettent un effort personnel, un travail qui est leur œuvre, qui exige un peu de réflexion, de jugement et de goût. »

Depuis la mise en place des écoles actives voici plus d’un siècle, l’activité justement et l’autonomie de l’élève, son plaisir de découvrir par lui-même, de se questionner et de chercher sont recommandés comme les meilleurs agents de la motivation. Les questions nourrissent la curiosité et entraînent la dynamique du « connaître ». Les attentes de l’enfant, ses projets jouent un rôle moteur, auquel contribuent fondamentalement la confiance dans ses compétence intellectuelles et l’estime de soi, que notre système scolaire met particulièrement à mal.

Fun Ideas That Keep Kids Learning Even After School's Out | #Coding: #LEARNingByDoing with #FUN

Fun Ideas That Keep Kids Learning Even After School's Out | #Coding: #LEARNingByDoing with #FUN | 21st Century Learning and Teaching | Scoop.it

Learning to Code


So, you like video games? Do you know that actual humans make video games with some type of computer code? It's true. But even better, kids can write programs too. It might seem scary to get started, but it's really not too bad. If you want to get started, I am going to recommend code.org. There are plenty of learning guides that are appropriate for a variety of ages. Oh, and it's free and online.

Even the lowest level activities are very complete—they even include ideas about functions and debugging. It's the best way to get a general idea of computer programming before moving on to a particular language.

If you want to be more creative with your programming, there is also Scratch (scratch.mit.edu). Scratch is a graphical (and free) programming language that focuses on the control of animated sprites. It's pretty easy to pick up and it's built so that you can share programs and modify others.

Finally, there is one more set of coding activities—physical programming. Physical programming takes some type of code but adds onto it some actual object that the code can control. If that sounds awesome, it's only because it is. There are two physical programming platforms that I have worked with before—Raspberry Pi and Arduino. Although these devices are not free, they aren't super expensive either. Both platforms have tons of great projects that kids (or adults) can work on.

 

Example: https://projects.raspberrypi.org/en/ and https://create.arduino.cc/projecthub

Arduino Playground - I2cScanner | #Coding #OLEDs #Maker #MakerED #MakerSpaces #LEARNingByDoing | 21st Century Learning and Teaching | Scoop.it

This very simple sketch scans the I2C-bus for devices. If a device is found, it is reported to the Arduino serial monitor.

This sketch is the first step to get the I2C communication working.

The sketch shows the 7-bit addresses of the found devices as hexadecimal values. That value can be used for the "Wire.begin" function which uses the 7-bit address. Some datasheets use the 8-bit address and some example sketches use decimal addresses.

Simple Arduino Audio/Music Player with SD Card | #Coding #Maker #MakerED #MakerSpaces #LEARNingByDoing | 21st Century Learning and Teaching | Scoop.it

Adding sounds or music to our project will always make it looks cool and sounds much more attractive. Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra SD card module and a normal speaker. In this article I will show you how easy it is to Play music/add sound effects using your Arduino Board.  

 

Thanks to the Arduino community who have developed some libraries to build this in a fast and easy way. We have also used IC LM386 here for amplification and noise reduction purpose.

 

[Gust MEES] GREAT music quality!!

Overview | Monochrome OLED Breakouts | Adafruit Learning System | #Coding #Maker #MakerED #MakerSpaces #LEARNingByDoing  | 21st Century Learning and Teaching | Scoop.it

This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

Pixy2 – PixyCam | #Arduino #RaspberryPI #Coding #Maker #MakerED #MakerSpaces 

Pixy2 – PixyCam | #Arduino #RaspberryPI #Coding #Maker #MakerED #MakerSpaces  | 21st Century Learning and Teaching | Scoop.it

Robot vision made easier


Pixy2 is smaller, faster and more capable than the original Pixy.  Like its predecessor, Pixy2 can learn to detect objects that you teach it, just by pressing a button.  Additionally, Pixy2 has new algorithms that detect and track lines for use with line-following robots.  The new algorithms can detect intersections and “road signs” as well. The road signs can tell your robot what to do, such as turn left, turn right, slow down, etc.  And Pixy2 does all of this at 60 frames-per-second, so your robot can be fast, too.

Use Pixy2 for lots of different applications, find a project, or use Pixy2 for something no one has considered!

Connect directly to Arduino or Raspberry Pi

No need to futz around with tiny wires — Pixy2 comes with a special cable to plug directly into an Arduino and a USB cable to plug into a Raspberry Pi, so you can get started quickly.  No Arduino or Raspberry Pi?  No problem!  Pixy2 has several interfaces (SPI, I2C, UART, and USB) and simple communications, so you get your chosen controller talking to Pixy2 in short order.

This time I will help you move the same 2 servos with a thumbstick. And again I have surf the internet to see If there are tutorials that clear to understand specially for the beginner Arduino user and, I have not found one.


To move 2 servos with the thumbstick is way easier and painless than using the mouse. And the reason for this is that some times the processing software does not work correct or there is a conflict between the arduino software and the processing software.

À l’école, le portable, c’est le couteau suisse du XXIᵉ siècle | #EDUcation #ModernEDU

Le potentiel des nouvelles technologies pour l’apprentissage et l’éducation est en grande partie non évalué. Il manque de recherche précise sur le sujet et notamment de recherches sur ce qui se passe dans le terrain et pour chacun des apprenants, et ce à tous les âges de la vie. Il y a peu d’évaluations en dehors de sentiments personnels.

L’une des questions centrales est : a-t-on appris à apprendre ? Et a-t-on appris à apprendre de manière critique à l’heure du numérique ? Car on peut aussi être manipulé par le numérique. Tout moyen de communication est aussi un moyen de manipulation, on l’a vu de Goebbels à Trump ou Daesch. Plus on a des outils de communication efficaces, plus il faut développer l’esprit critique et la capacité à distinguer le bon grain de l’ivraie, ce qui est tout sauf évident même pour un adulte et a fortiori pour un enfant ou un adolescent.

Par contre ce que le numérique permet, par rapport à la radio par exemple, c’est qu’on peut tous produire et partager et que l’on peut facilement documenter ce que l’on fait. On peut échanger plus largement et à toutes les échelles.

Gust MEES's insight:

Le potentiel des nouvelles technologies pour l’apprentissage et l’éducation est en grande partie non évalué. Il manque de recherche précise sur le sujet et notamment de recherches sur ce qui se passe dans le terrain et pour chacun des apprenants, et ce à tous les âges de la vie. Il y a peu d’évaluations en dehors de sentiments personnels.

L’une des questions centrales est : a-t-on appris à apprendre ? Et a-t-on appris à apprendre de manière critique à l’heure du numérique ? Car on peut aussi être manipulé par le numérique. Tout moyen de communication est aussi un moyen de manipulation, on l’a vu de Goebbels à Trump ou Daesch. Plus on a des outils de communication efficaces, plus il faut développer l’esprit critique et la capacité à distinguer le bon grain de l’ivraie, ce qui est tout sauf évident même pour un adulte et a fortiori pour un enfant ou un adolescent.

Par contre ce que le numérique permet, par rapport à la radio par exemple, c’est qu’on peut tous produire et partager et que l’on peut facilement documenter ce que l’on fait. On peut échanger plus largement et à toutes les échelles. On a donc cette possibilité, non seulement d’apprendre à lire, écrire mais d’accueillir une production faite par d’autres et de soi-même produire, via l’écrit ou tout un tas d’autres dispositifs que le numérique permet.

MP3 player using Arduino and DFPlayer mini | #Coding #Maker #MakerED #MakerSpaces

MP3 player using Arduino and DFPlayer mini | #Coding #Maker #MakerED #MakerSpaces | 21st Century Learning and Teaching | Scoop.it

Today, we will build an mp3 player using an Arduino and the DFPlayer mini MP3 module.

The DFplayer mini is a small, low-cost mp3 module with a simplified audio output that can be connected directly to a speaker or an earphone jack. The module can be used as a stand-alone module with attached battery, speaker, and push buttons or used in combination with a microcontroller or development board like the Arduino, enabled for RX/TX (Serial) communication, thus through simple serial commands we can play music and perform other functions like playing the next and previous song, shuffle, pause the song currently being played etc.

 

The module comes with an SDcard slot and supports both FAT16, FAT32 file system.

Archimedes: The AI Robot Owl | #Coding #Maker #MakerED #MakerSpaces #RaspberryPI

Archimedes: The AI Robot Owl | #Coding #Maker #MakerED #MakerSpaces #RaspberryPI | 21st Century Learning and Teaching | Scoop.it

ABOUT THIS PROJECT


This is a robotic owl that looks around for cool people, and can tell whether you're happy or upset. If you're excited enough, he will eventually let you take a sticker (or other small giveaway). He's named Archimedes, after Merlin's familiar in TheOnceandFutureKing. Of course, it's also reminiscent of the cyborg owl in Blade Runner.

First up, if you don't know the Google AIY Vision Kit, check out the details here! This is the basis for the robot's smarts. The code for this project is coming soon.

It started when we were invited to contribute something to the Google booth at Bay Area Maker Faire. I took a really, really long time to figure out what to build—what it would look like, how it would animate, how it would dispense the stickers... in the end, I went with this cute and fairly challenging design.

This robot is versatile enough that I can bring it along to different events, such as the CODAME Artobots Festival and the Arm/Hackster Asia Tour (since the Raspberry Pi runs on an Arm chip, the Broadcom BCM2835). In other words, I can justify spending this much time on one project because I can re-use and iterate upon it. I'm also excited to have a sidekick in the office :)

Bitmaps & Code | OLED SlideShow | Steampunk Cameo Necklace with OLED Display | Adafruit Learning System | #Coding #Maker #MakerED #MakerSpaces | 21st Century Learning and Teaching | Scoop.it

Bitmaps & Code by Leslie Birch

 

Time to create two image files and convert them into a code the OLED can understand.

Use Photoshop or another imaging program to create two cameo profile pics and turn them into bitmaps (.bmp). They should be monologue and 128x64 pixels. Notice I had my images each facing another direction.


Download LCD Image Converter and run.


Choose New Image and create a name. Then hit enter.
Now choose Image and Import. Select the file.
Now choose Options and Conversion, then Prepare. The followiing should be checked: Type:  Monochrome, Threshold Dither, Main Scan Direction: Left to Right, Line Scan Direction: Forward 
Now select Image. Make sure Select to Rows is checked. 8-Bit and Little Endian.


Hit OK, then File, Convert. Name the file. Now do the same process for your other file. The completed files will contain a series of code that you need to cut and paste into the project code to replace the files I provided. It will look something like this, only longer. Note that you don't need the beginning name, just the brackets and what is contained within them...

Graphics Primitives | Adafruit GFX Graphics Library | Adafruit Learning System | #Coding #Maker #MakerED #MakerSpaces #LEARNingByDoing | 21st Century Learning and Teaching | Scoop.it

Graphics Primitives by Phillip Burgess
Each device-specific display library will have its own constructors and initialization functions. These are documented in the individual tutorials for each display type, or oftentimes are evident in the specific library header file. The remainder of this tutorial covers the common graphics functions that work the same regardless of the display type.

The function descriptions below are merely prototypes — there’s an assumption that a display object is declared and initialized as needed by the device-specific library. Look at the example code with each library to see it in actual use. For example, where we show print(1234.56), your actual code would place the object name before this, e.g. it might read screen.print(1234.56) (if you have declared your display object with the name screen).
