Hello. Over time I've built a lot of electronic projects using the PC's parallel port. For instance, I've built a simple car, running with 2 stepping motors. There's a long cable that goes from the parallel port's 8 TTL outputs and to the car.
Right now it looks like this
8 outputs/inputs from the parallel port

a 2803 chip on the car

other stuff needed to make the car go
What I would want to do, is simply replace the wires. I'd need a transmissor, and a receiver capable of receiving the 8 outputs and giving the 2803 chip onboard the TTL levels it needs. Of course, I'd also need to power the car with a battery or something, thus replacing the power supply's wires also, but that's beyond the scope of this post.
What would be the simplest way of building this?
