With this sketch you can control pins of a remote Arduino board through ESPHome. The Arduino acts as a port expander, allowing you to use more pins than a standard ESP8266/ESP32 has. The Arduino is ...

This simple project shows how Arduino can be used with a real time operating system (Erika). The project is designed to show how Arduino can be integrated with a Real-Time operating system and how to ...

Arduino is probably the first thing that comes to mind for most hobbyists and students when they think about embedded systems. It has certainly gained its name among the electronics community, and in ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

There are plenty of toys and board games that can teach kids about electronics, science and how things work, but few are as effective as an Arduino kit. These bundles include everything you need to ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino ...
