You need to first disassemble the RC car remote and connect some jumper wires to the pins connecting directly to the RF IC.
Then you need to connect the RF remote board to a ESP32-C3 based microcontroller board.
Connect the RF pins to the microcontroller as per the table below:
| RF Remote | ESP32-C3 GPIO |
| Move Forward | 7 |
| Move Backward | 6 |
| Turn Left | 3 |
| Turn Right | 2 |
| Head Lights | 10 |
| Turbo Mode | 0 |
Connect your ESP32-C3 board to your computer via USB. Then go the CodeSkool >> Board >> Upload Firmware
and select the Whizz RC Car firmware, then connect using the microcontroller COM Port and flash the firmware.
Reset your microcontroller, add the Whizz Car extension and connect to your RC car and enjoy CodeSkool Scratch programming.
