Hello
I am using a Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack - Green - on a Arduino UNO R3 and I would like to use analog input 0 but with the Adafruit_LEDBackpack library running I am getting 2.5v out on analog pins A0-A3 with the backpack's SDA and SCL in A4 and A5. If i run a sketch without the library but with the backpack plugged in analog inputs work fine. The 7 segment display is working fine. Please help.
Thank you

What do you mean, you're getting 2.5V out on the analog pins? You're seeing that with the pins configured as inputs? Can you post some pictures of your setup?

Thanks! I didn't know i needed to configure the analog pins as input or output. I thought that was only for digital I/O.adafruit_support_rick wrote:What do you mean, you're getting 2.5V out on the analog pins? You're seeing that with the pins configured as inputs?
