From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

Last week I explained how to use a motion sensor to trigger an event with an Arduino. The event we triggered was a simple blinking of an LED. You can do a lot with a bunch of LEDs if you use your ...

Description: This project allows for controlling the brightness of a Blue LED using a potentiometer and toggling between manual brightness and auto blink mode using a push button. A 2N2222 NPN ...
