Description
Multi purpose Arduino Uno shield with breadboard connection
The board has these sections
· An audio switch
· An analog trimmer connected to an Arduino analog pin
· Two push-buttons
· A 5mm RGB LED
· A 10 A SPDT relay
· A connector in order to install a Wi-Fi ESP8266 module
· A 3.3V 1 A LDO
· There are two headers in order to connect the shield to a a breadboard
I have created this project as a reference project for a Italian PCB Design Course called PCBSemplice that I have recorded
