21st Century Learning and Teaching

A “brown out” of a microcontroller is a partial and temporary reduction in the power supply voltage below the level required for reliable operation. Many microcontrollers have a protection circuit which detects when the supply voltage goes below this level...

Pedometers are the devices that only used to count footsteps. So in this tutorial, we are going to build an easy and cheap DIY Pedometer using Arduino and accelerometer. This Pedometer will count the number of footsteps and display them on a 16x2 LCD module. This pedometer can be integrated with this Arduino Smart Watch.

This project builds upon the previous digital image camera project and we build a time-lapse camera using the ESP32-CAM board. All the images are saved to the microSD card in sequence and the board goes to sleep after taking an image to help save power. This is handy if you power it using a battery.

This article includes everything you need to know about controlling a 28BYJ-48 stepper motor with the ULN2003 driver board and Arduino. I have included datasheets, a wiring diagram and many example codes!

First we take a look at the easy to use Arduino Stepper library. This library is great when you are just starting out, but doesn’t have many extra features.

I highly recommend to also take a look at the example codes for the AccelStepper library at the end of this tutorial. This library is fairly easy to use and can greatly improve the performance of your hardware.

After each example, I break down and explain how the code works, so you should have no problems modifying it to suit your needs.

Servo ansteuern (Arduino, ESP8266, ESP32) In diesem Beitrag möchte ich euch zeigen wir Ihr einen Servo mit einem Arduino, ESP8266 (Wemos D1 mini lite) und ESP32 (Wemos Lolin32) betreiben könnt. Das ansteuern des Servos ist beim Arduino und ESP8266 das selbe Prinzip nur beim ESP32 gibt es eine Neuerung. Für Arduino und ESP8266 wird die Funktion analogWrite() verwendet, die kennen wir alle, doch diese Funktion gibt es mit dem ESP32 nicht mehr. Wen man diese Funktion nutzen möchte muss man nun mit ledcWrite(channel, duty) arbeiten, wie das genau geht zeige…

Arduino is the largest open-source hardware platform in the world that provides unlimited possibilities that can be achieved using microcontroller-based products. Therefore, Arduino starter kit is a perfect way to dive into electronics and programming as you get all the essential components in a single package which is required to start working with Arduino.

In fact, there are so many Arduino starter kits available online, each offering a variety of components, and the only thing you need to do is to choose one that will suit your needs the most.

These Arduino Kits are good for students, as well as for people who have very little or no experience in electronics and programming, but are willing to learn more.

We have given all the information needed to help you decide which Arduino starter kit is the best for you, from price, items included, some pros and cons of the kits. Still we can not choose one as the best Arduino starter kit as each kit is unique in its own way.

If you are from a technical background or have some interest in Computers or Electronics, then you must have heard the name Magic Mirror. Basically it is to turn your regular Mirror into a gadget or monitor, which will show you all the updates like news, whether, stock prices etc. There are many kind of Magic mirrors from the basic one to the advanced touch screen mirrors. Today we are sharing one very interesting and cool Magic Mirror which not only work as a monitor but also talk to you with a ‘face’ like a Artificial Intelligence in your home.

ESP8266 modules are great low cost stand alone controllers with built in Wi-Fi. In this Instructable I will show you how you can control a Servo remotely over Wi-Fi with a Rotary Encoder. The Instructable is a similar but more advanced version of the "Arduino Nano and Visuino: Control Servo with Rotary Encoder" Instructable.

In the Instructable, I will use 2 NodeMCUmodules. One version 0.9, and the other 1.0. The NodeMCU are the easiest way to program and experiment with ESP8266controllers. This Instructable however can easily be done with other modules, and the Servo module can even use ESP-01 module as it needs only one GPIO pin to connect to the Servo.

In this tutorial, I'll show that how can we make an ESP32-CAM based video server which can be hosted on a local server.

This project is sponsored by LCSC. I have been using electronic components from LCSC.com. 

We can set up a video streaming web server with face recognition and detection in less than 5 minutes with Arduino IDE.
