By connecting an RC receiver and running this example program, you can turn your Zumo into a radio-controlled vehicle. With the Zumo Shield Arduino Libraries installed, the sketch file can be opened in Arduino by selecting '''File > Examples > ZumoExamples > RCControl'''.
By connecting an RC receiver and running this example program, you can turn your Zumo into a radio-controlled vehicle.

An easy way to connect the receiver to the Zumo Shield is to solder two 1×3 male header strips {{polpl|966}} to the locations shown in the diagram below, then plug in a pair of standard servo cables <small>[https://www.pololu.com/category/112/servo-cables lien pololu]</small>between the receiver and the Zumo Shield. (If your receiver has a separate power source, you should only connect the signal and ground wires between it and the Zumo.)

This program uses Arduino’s [http://arduino.cc/en/Reference/PulseIn PulseIn library] to read the signals from the receiver. By default, it assumes the throttle and steering channels are connected as the diagram shows on pins 4 and 5, respectively. The signals from the two channels are mixed to determine the left and right motor speeds, allowing for more intuitive control.
