Hi! I noticed that in the 'code.py' file it's mentioned that you can switch between 4 payloads by connecting GPIO pins 4, 5, 10, 11 to ground. What code would I need to modify to change those pins like this:
Payload 1: GP16 to GND
Payload 2: GP4 to GND
Payload 3: GP11 to GND
Payload 4: GP20 to GND
I attached a picture of what it would look like.

Also, I'd love to see details for multiple payloads on the readme, as I accidentally stumbled across it by reading the script. Thanks in advance!
