Hi everyone, today I will teach you how to make a steering car with our micro:bit Wonder Building Kit, the principle is very simple, mainly using the rack and pinion steering gear and the unstable structure of the parallelogram.
Sonar:bit is a 3-wire ultrasonic module with the working voltage between 3-5V. It is available to be used to 3.3V or 5V micro-controller system. With only one 3-wire(GVS) cable, it can work properly. Compared to the normal 4-wire ultrasonic module, it has saved one IO port. The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with ±1cm tolerance only.
