After many hours I was able to piece together some what of a working sketch.
I am still unable to make the second keypad function,
I soldered the ADR to make the jumper on 1 of the keypads to change address and verified it with the I2C Scanner example. It now shows to be 0x4A.
Any help in showing me how to add a second keypad to my sketch would be outstanding.
Here is my current sketch.
/*
1 BLACK Board with Qwiic connector
1 Qwiic MP3 Trigger
2 Qwiick Keypad
Object of this sketch is to use two Keypads to Trigger the MP3 files
1 keypad address normal 0x4B
1 keypad address changed to 0x4A by jumping the ADR on board
To all be used on same bus
SD card loaded with some MP3s in the root directory
Plug the Qwiic device onto an available Qwiic port
Open the serial monitor at 9600 baud
