Review on KEYESTUDIO Multi-Purpose Shield V2: 4-Digit LED Display, Buttons & Buzzer for Arduino Mega Microcontroller, Electronic Programming Project by Jerry Anderson

I ordered this shield for my Civil Air Patrol cadets to be able to program the Arduino Uno to tell the time, create a multi key calculator or even multiple motors to move a robot. Let the fun and imagination run wild as you create your own sets and features. The screen is fitted with LED indicators, one or two relays and resistors that can be used to turn on the LEDs in the event of a fault or condition. I would recommend this to anyone using STEM kits etc.
