ARDUINO UNO is Associate in Nursing ATMEGA controller primarily based board designed for electronic engineers and hobbyists. Arduino primarily based program development surroundings is a straightforward thanks to writing the program in comparison to alternative surroundings development programs.

Circuit Schematics

First, connect pin thirteen on your Arduino to a spot on your board, then your electrical device. On the opposite facet of the electrical device, insert your crystal rectifier.

NOTE: LEDs are polarised, which means that they need an explicit approach they have to be connected if you’re to not blow them. Connect the positive lead of the crystal rectifier to the electrical device and run a wire from the bottom cause the GND pin on the Arduino. The result ought to appear as if the schematic on this tutorial.
