hello,
I am currenty working on an engineering project for school. My project is a phone charger that turns on and off when the phone reaches a certain battery percentage. The way that the charger turns on and off is by an app on the iphone sending a signal through bluetooth to a bluetooth arduino telling it to start or stop the charge. The bluetooth arduino that I am using is a Adafruit Feather 32u4. Can anyone help me with this code. I am pretty new to programming and this is my first time using xcode. Anything will help. Thank you in advamce.
