Using an 8×8 LED array with Arduino

The 8×8 LED array has 8 rows and 8 columns of individually controllable LEDs. LED arrays can be useful for advertising signs, temperature display, and so on. Material Computer Arduino UNO USB A Male Cable LED array Principle of operation The LED matrix module contains...
Using a transistor module with Arduino

Using a transistor module with Arduino

The transistor module is composed of an electronic component, which can be seen as a controllable switch, which lets pass a current proportional to the voltage at its terminals when it exceeds a certain threshold. It allows, with a very low power signal, to supply a...
Using a Reed Switch (ILS) with Arduino

Using a Reed Switch (ILS) with Arduino

A reed switch or ILS is a magnetic sensor that detects the presence of a magnetic field. This switch will be activated by approaching a magnet. It can be used to know if a door is closed or open or to detect the presence of an object. Material Computer Arduino UNO USB...
