Review on KEYESTUDIO Multi-Purpose Shield V2: 4-Digit LED Display, Buttons & Buzzer for Arduino Mega Microcontroller, Electronic Programming Project by Kaveen Reyes
Ideal for showcasing Arduino programming
A great way to show some *Physical Computing* examples is to connect your Arduino to the real world. Download a simple demo program to demonstrate a four-digit digital display, a buzzer, six independent LEDs, an ADC (analog-to-digital converter), and three pushbutton switches. You can find an online manual by googling the product name. [Revain didn't let me post the URL.] All pinouts are explained, but it would be nice to have a full schematic.
