3.9 The Infrared Receiver
The Infrared Receiver module allows you to simply control your Versabot using a TV-like remote
control. The TV remote control, if required, is available separately as part TVR010.
1. Attach the Infrared Receiver module to Pin 6 on the Versabot motherboard.
2. In order to use the remote control with the microcontroller, you will need to follow a sequence
of steps to preset the remote to work with the microcontroller.
a. Put two AAA batteries into the remote control unit.
b. Simultaneously hold down the S button (in the middle of the arrows) and the B button
on the remote (a red light will go on in the top left hand corner of the remote.)
c. Press the number sequence 0 1 3 on the remote buttons.
d. Press the red power button on the remote.
e. The remote is now configured to work with your microcontroller.
Note that buttons A, C, D, E, F and G are for setting the remote control into different modes which
are not required for this project. Avoid pressing these buttons as this will inadvertently set your
remote into another mode. You can always return to the ‘B’ mode by pressing the B button.
3. Start the Programming Editor or AXEpad , or start a new program by using the
File/New/Basic Program menu option.
4. In this program you will be using the infrain command. This is a command that tells the
microcontroller to wait for a remote control signal.
