Another IR Board Problem

[C222]

So, my team has had some problems with our IR board. We had to replace the voltage regulator, went through 4 remotes that didn't work. now we have a remote that seems to work, however, when the board switches out of learn mode the LEDs don't light up when we send the commands to the board again.

help... please.


Edit: every time we reboot the board after learning the error light comes on for about 1 second.

This is really similar to what is happening to us.

At first our IR sensor was hooked up to a prototype board and it worked well. It was receiving signals from the remote control and everything.

But then, in the course of hooking it up to our test bot, we reversed the pwms, mistakenly plugging the white signal wire into the ground on the digital in/out section.

Since then our board will train perfectly, but when we send a signal after training it, it just blinks an error light repeatedly until we power down.

We checked our 5 volt regulator and it is functioning just fine, and we never smelled any smoke. We also tried two different remotes which each worked when we had the IR Sensor hooked up to our original prototype board. When even rehooked the sensor up to its original prototype board, but it still doesn't work.

I don't have any idea on how to fix this problem, anyone else have any ideas?

If you have killed the five volt regulator, then I always suspect the parts connected to it. The board is talking to you. Although you think it has learned the commands it is telling you it has not.
