Valenta Off Road Vehicle

For BBC Microbit

The Valenta range of motor driver boards has been specifically engineered to be used as the main control unit for a range of injection moulded vehicles.

The Valenta Zero is the same size as the DriveBit and ServoBit products from 4tronix (and also the same size as a Raspberry Pi Zero). It contains a small motor controller (DRV8833) as well as connections for general I/O and servos (can be selected to operate at 3.3V or 5V using a jumper or switch).

A Makecode extension is available to drive both the Valenta Zero and the Valenta Plus. In the Advanced | Extensions search box, enter this URL to find and load the extension: https://github.com/4tronix/Valenta

This provides generalised commands to drive motors, servos and Fireleds (where available). To drive this Off-Roader vehicle, note that:

• Motor 1 is the left motor
• Motor 2 is the right motor
• Servo 8 is the steering servo connected to Pin 8 of the Microbit
• (There are no headlights or Fireleds on this prototype)
