Controlling RGB LEDs With The Pi Zero

Controlling RGB LEDs With The Pi Zero | Raspberry Pi | Scoop.it

The Pi Zero is a great piece of hardware, even if you're not designing another USB hub for it. [Marcel] wanted to control a few RGB LED strips from his phone, and while there are a lot of fancy ways y...

Spare RasPi To Get Kids Coding

Spare RasPi To Get Kids Coding | Raspberry Pi | Scoop.it
Hi, I'm Joe and this is my first Instructable.I wanted to share how I got my son into coding with the Raspberry Pi. For some background he is a very tech heavy child and loves, loves, LOVES his video games. It only took me telling him that he "could make his own games with his own rules" to sell him on the idea. I took what knowledge and resources I had and went to the only place I knew that could help me, Google. Searching with some key words like "coding" "kids" "Raspberry Pi" came up with mostly one resource, The Kano Computer. This is an excellent organization that wants to get kids into coding and has compiled an all-in-one kit to get them started. After reading that they use the Raspberry Pi (which I already had) and some other peripherals, I was in. Now, my sons interests are very ...

IoT Garage Door v2

IoT Garage Door v2 | Raspberry Pi | Scoop.it
A year or so ago, I hacked a Belkin WeMo switch and coupled the WIFI board to an Arduino Uno along with a little code and sensors to create a way to control my garage door. The system worked well as I could not only control the door, but I could see the door's state in the WeMo App on my iPhone. The only problems were that the parts were fairly expensive ($50 for the WeMo and $20 for the Arduino + sensors) and the sensors (magnetic reed relay or hall effect) were difficult to install reliably in the garage.So I set out to simplify the design. I wanted to reduce the price and also make the installation something a typical homeowner might be able to do.The new design uses an internet development chip/system called the Particle Photon. The system is essentially an arduino type processor coupled to a WIFI ...

SparkRover - 3D Printed Smartphone Controlled Robot

SparkRover - 3D Printed Smartphone Controlled Robot | Raspberry Pi | Scoop.it
Over the years, I have built several large robots using a custom-made robotics driver that I created called the SmartRover system. This driver was initially used for my SmartRover robot that I built which ran at a peak current of 60 amps at 24 volts. Obviously, the SmartRover can be overkill for many beginners. With the intentions of sharing the fundamentals of robotics with my club and with many members being interested to acquire hands-on skills with robots, I decided to design a DIY robot of a smaller scale. This ultimately became known as the SparkRover, an affordable robotics kit that I exclusively dedicated to sharing with the Purdue Mechatronics club.The SparkRover is an open-source 3D printed robotics kit that can be controlled by a Smartphone and can avoid walls. This robot can be controlled through Bluetooth and can be a great way for beginners to learn about the Arduino ...

PWM based RGB LED colour control using Raspberry Pi 2 and ScratchGPIO 7

PWM based RGB LED colour control using Raspberry Pi 2 and ScratchGPIO 7 | Raspberry Pi | Scoop.it
I have written this instructable as a follow up to my previous instructable where I controlled the brightness of an LED using buttons and ScratchGPIO 7. You can find the details of how I did that here:http://www.instructables.com/id/PWM-Based-LED-Cont...This time round, I decided to try to write a program using ScratchGPIO 7 that would sweep through the colour range of the RGB LED from red to green to blue and back to red. I got a bit lost for a while inside all the if loops, but I think I have now got something that does the trick. Any comments and suggestions as to how to make the program better would be much appreciated.

The ratPhone - 3G FONA Arduino Cellular Mobile Cell Phone with Retro Push Button Keypad and Rat Catching App

The ratPhone - 3G FONA Arduino Cellular Mobile Cell Phone with Retro Push Button Keypad and Rat Catching App | Raspberry Pi | Scoop.it
Never mind the iPhones and Androids. Here's the ratPhone! This is definitely NOT a smart phone. But it's not a stupid phone either. You will not be able to waste endless hours on Facebook or Twitter, but it will help you catch rats and other pests that would otherwise eat all your potatoes.My overiding requirement with this project was that the code used should be really simple and well documented so that I could come back to it at any time in the future and understand what I had done. For this reason I have deliberately kept the first part of the project limited to the most basic functions - type in a telephone number, make a call, answer a call and hang up. It would be easy to get carried away with using endless functions and creating complex menus, but to understand the core elements of the code it ...

NRF24L01+ ATmega328P-PU Radio Sensor

NRF24L01+ ATmega328P-PU Radio Sensor | Raspberry Pi | Scoop.it
This project began as an attempt to create a custom sensor board that functioned with an nRF24L01+ radio transmitter. I was tired of looping wires around an Arduino Uno. I thought I could create a custom solution in a fairly small footprint, that would allow the connection of a number of common sensors. After a number of prototypes and two custom PCB attempts, this is the design I came up with.The design is centered around an ATmega328P-PU and the nRF24L01+ 2.4GHz transceiver module. This device will allow the transceiver to be plugged directly into the board, and supply it with 3.3volts. The ATmega328P will be supplied with 5 volts. This is all contained in a 40 x 60mm footprint (the nRF24L01+ does create a slight overhang along the long axis). Also two small prototyping areas (3 x 8 holes, and 2 x 4 holes) are created on the board, allowing ...

Hi, and thanks for taking some time to read my amazing tutorial. My little sister's birthday is on February 25, she is turning 29 and I guess she started feeling a little bit old because she asked me to give her one of my Super Nintendos and a Super Mario World cartridge (I have 2 SNES and a SFC with about 150 games) but I decided to do one better and I bought her a Raspberry Pi, and made two awesome arcade style controllers for it. I documented most everything I did so there will be lots if pictures and I'll do my best to try to explain how you too can make something like this. Also I want point out that yes I'm wearing crocs and no it's not just because I'm a slob lol it's also because it's because my back is broken and my feet swell after ...

Cougar Run a simple Arduino game.

Cougar Run a simple Arduino game. | Raspberry Pi | Scoop.it
I built this Arduino/Processing game as a school assignment. The assignment was to build an Arduino game and i decided to build mine as a simple arduino circuit and a more complicated software design. The way the game works is your character, a cougar, (my school mascot) moves up and down and depending on the pressure applied onto the pressure sensor. The harder you push on the pressure sensor the higher your character goes. The goal of the game is to go through the two rectangles without hitting into them. Once the game picks up power ups become available and you can either get a ghost, which allows you to go right through the rectangles without dyeing or a snail power up which slows down the game making it easier to safely go through the two rectangles.parts: force sensor (around $5.00)10k ohm resistor (basically free)Arduino (i used an uno but ...

Arduino (Increase Power Port Pins)

Arduino (Increase Power Port Pins) | Raspberry Pi | Scoop.it
Hello friends,This instructable is show you how to increase the number of power port in arduino board. In arduino micro-controller we have only few pins for power. For example we have only 1 port for 5V power supply in arduino uno r3. When we require many 5V port than we connect so many jumper wire and use breadboard. As a result the wires are look like a net of wire. If we connect a wrong connection of wire. Then find out a wrong wire connection is quite difficult. To overcome these types of problems follow this instructable.
