IR signal transmitting test

A project log for Jimmy the mouse bot

I'm building a mouse bot based on the Parallax Propeller microcontroller.

I connected a IR LED on a little breadboard with my Propeller One board. And did try some signal sending to my mouse bot. It's a 4 bit signal sent.

The signal receiving on the mouse bot didn't work right. I use counter loops to "measure" the duration of the IR pulses. A one is send as a 2 ms on and a 1 ms off pulse. And a zero as a 1 ms on and a 1 ms off pulse.

Now I'm working on the decoder to get the signal right. I have to take care of not make the decoder loop endless waiting for a signal change which never comes. So I have to add a counter break if some high value is reached.

The goal is to build a remote control for the mouse bot. Or at least try that.
