Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month
Product well designed and ready for use.
Just plug and play. Note that board has to verify the connection. In my case it worked without problems with an Arduino Mega.
Verify that the keys are connected to analog inputs.
With the examples in internet you can quickly develop a simple menu.
Working with analog inputs for the buttons you may not learn well the concepts of rebounds that occur with digital inputs and buttons.
Reading the examples for Arduino will learn quickly the operation of the module.
Not bad, but I do not like that the buttons are connected to the analog inputs.
Simple and cheap.
This module is a must if you have any Arduino.
