I am trying to use the Bluetooth & LiPo Add-On for Makey Makey with a ProMicro instead of makey makey.
I hooked it up as follows:
BT Mate 4 MM Pro Micro 3V
Vcc Raw
GND GND
Tx Rx
Rx Tx
I also have a lipo plugged in to the BT/Lipo unit
The problem is that it seems to pass the power from the battery to the ProMicro fine and it seems like it goes into charge mode when I plug in the usb to the ProMicro, but I am not getting the pc to see it. I am also not getting any lights on the BT unit except for a yellow light when its charging.
I think the charger part works but the BT part may be dead. Are there any status lights that should be on when the unit is powered via the lipo battery???
Do I need to wire anything differently???
