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

Assembly

Please follow the steps shown in this video and outlined in the included User Guide

Programming in Makecode

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)
