Use the Kittenbot Robotbit expansion board (not the micro:bit pin header).
- Insert the micro:bit V2 — buttons A and B face outwards
- Power Robotbit (battery activate + switch ON, or USB on the micro:bit for programming)
- Plug servo 1 into socket S1
- Plug servo 2 into socket S2
Wire colours on the socket:
- Brown / black → GND
- Red → V+
- Orange / yellow → signal
Tips
- Program through the micro:bit USB, not the Robotbit USB.
- Do not plug servos into pin P0 — that is the buzzer.
The editor already has the Teknubi program: A toggles S1, B toggles S2.
Click Next when both servos are on S1 and S2.
