In the tutorials section, you’ll find articles on using Arduino components, Linux systems such as the Raspberry Pi and other microcontrollers such as ESP32. You’ll also find programming tutorials in C/C++, Python, JavaScript and other languages, as well as software development and web, Android and PC graphical interfaces. You’ll also see tutorials on wired and wireless communication between different systems.
Installing ROS2 on Raspberry Pi
In this tutorial, we'll look at how to install ROS2 on a Linux machine, in particular a Raspberry Pi 4 running Ubuntu. ROS2 is an interesting framework to tackle when working on embedded systems such as robots. Hardware Computer with Internet access 32GB SD card...
Sending long character strings via BLE
Bluetooth Low Energy (BLE) has a known limit of 20Bytes on the length of strings sent. There are ways of overriding this limit. Hardware In this tutorial, we'll send data from an Android application, developed under React Native, to an ESP32. The methods described may...
Give your Android device a voice with React Native TTS
In this tutorial, we'll look at how to give your Android device a voice using a Text to Speech (TTS) library. Whether you're developing applications for the visually impaired, or just want to liven up your Android system, giving your project a voice can be an...

Control 8 relays using ESP32 and serial monitor
In this tutorial we will see how to address each relay individually with a NodeMCU32S microcontroller and 74HC595 shift registers. At the end of this tutorial you will also be able to control each relay using the serial monitor. This tutorial follows on from the...
Controlling 8 relays with ESP32 and shift register
In this series of tutorials, we will see how to drive a multitude of relays with a NodeMCU32S microcontroller and 74HC595 shift registers. We will then see how to address each relay individually. Finally, we will create a web interface to control each relay via the...
Adding the F() function to an INO file with Python
One of the big interests of programming is to automate simple tasks. A good example I have encountered is the modification of several lines of code in an INO file for Arduino. After writing a few dozen lines of code in C++ for my Arduino project, I found myself with a...
