RC-car remotely controlled from a computer. A demonstration of the power of Pytelemetry/telemetry. MIT Licensing.
Dependencies: BufferedSerial FRDM-TFC mbed telemetry
Example of the 'Telemetry' library, a portable communication library for embedded devices. The PC-side of this code is hosted a github.com/Overdrivr/telemetry-examples
This code uses the car from the Freescale Cup competition initially dedicated to be a line-following racing car, and turns it into a full-blown radio-controlled car.
It is using a Bluetooth serial module to provide wireless connectivity. See the repository at github.com/Overdrivr/telemetry-examples for complete instructions on wiring everthing together.
