There are lots of different ways to attach the Feather board:
- extra Lego to hold the board in place,
- a custom-made 3d printed holder,
- two pieces of black insulating tape.
The last option was used with the battery hanging off precariously.
The LED must be aligned with the photodiode light sensor. In bright conditions it may help to cover/shroud this area to stop ambient light interfering with the light pulse communication.
Ensure the Micro Scout brick is in P mode, tap connect in the tablet for the BlueMicroScout and start sending commands to the droid:
Button -> Action
- Up -> Reverse
- Down -> Forward
- 1 -> Beep
It's possible the droid in this example is built incorrectly with the direction mechanically reversed. The intention of the code is for the direction to be the other way around!
If the droid starts misbehaving by following a different command, this is likely to be due to a reported bug.
