The LCD provides invaluable insight what the vehicle is doing, critical for debugging and tuning the code. It also looks cool! While running, the main screen shows the following information: Row 1: 1. tH = Target Heading, the course to the current waypoint; ...

We will connect LEDs now but they wouldn’t be used in the first code. We will use them in the second one. If you use a different IR receiver, it is possible that you will need to add resistors, you should check the datasheet of the IR receiver. ...
