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
