  • I got one of these and had problems because I was using and Chipkit MAX 32. The reason for this is the the buttons are made to be read from a 5v ADC source. On the Arduino Due, Chipket Uno 32, and Chipkit MAX 32 operate on 3.3v. So what is happening is any voltage read from the ADC over 3.3v is read as 3.3v. What I did to fix the problem is change the resistor at R6 from a 2k to a 3.9k. This is a simple fix and the buttons work great now. The LCD Button Shield is a great product and hope if you are looking at any shields that are made for the Arduino UNO that you make sure it does not require the 5v ADC reading.

No public wish lists :(
