The 1/10 toy level car has a spring loaded servo for steering.

The steering servo and the DC motor for the wheels are driven by + - 7.2volts. I have four coil driven DPDT relays doing this job. They are not fast, but they are robust and reliable.

Today I am thinking about teaching the teachers. I need to come up with lesson plan #1. I am imagining kitting some of my cars then asking the teachers to implement "HELLO WORLD" (whatever that is for one of my RC car PIC systems.)

Question for you all.
What would be a HELLO WORLD for a 1/10 toy level PIC'd car?
