Apologies complete novice here. I bought a Raspberry Pi Pico and RGB keypad with the express intention to learn about microprocessors. I managed to get the RGB Keypad demo.py to run. The buttons all light up one calour but the keys do nothing - so I assume I have a bad solder joint.
Attaching the headers was my first attempt at soldering and I may well have damaged the pins or the pico. Any tips or pins I should be focusing on? Or is is a software thing I have missed?
Thanks in advance.
