Do you have a problem with the IR Board?

[DonRotolo]

If you are having problems with the IR Receiver board recently sent out as the FRC Game Hiunt, then please post your observations here. Please try to stick to facts, so that IF there is a real problem the people who can correct it have good data with which to work.

Symptoms, actions and measurements!


From another thread,

Tally so far:
358: LEDs flash during learning. After, either error light or nothing
456: Totally dead, 78L05 has no output
1357: Worked, then 78L05 fried. Maybe anti-static bag?
2144: Board works, LEDs do not light
2199: Error LED lights sometimes, not "0" (learn loop) LED

we tried hooking up our board today, and we hooked it up to a 9-volt battery, after that it flashed, and went dead, we tried to turning it on again and nothing happened, did we do something wrong, and is there a way to make it work?

Your 5 v regulator probably died. Our team's died awihle back. Just get a new 5 v regulator.

This has been happening to a small number of teams. No apparent reason though.

you may have shorted the board out on something. You did not have it sitting on the anti-static bag did you?

werecan we get a 5v regulator and how do we replace it, also wut if we did short out the board

I heard there was somewhere you could get a new board, but i don't know where or how.

as for the regulator... you probably want a 78L05, which is the exact same as the one on the board. assuming yours is bad of course. I have no idea where to get one. I looked at radio shack, but they did not carry it here. Ok to test if your regulator is bad ... apply standard voltage and use a multimeter to see if 5 v is coming out one end of the regulator pins. I think you will want to test the two outer pins, but i can't remember. by touching one of the pins on it, and one to ground you should detect the input voltage too. therefore detecting if voltage is even reaching the regulator.

...on the wild side... maybe your LED's are backwards. In that case your board may be fine, but not lighting up. you can easily test this by getting a good led and bridging it's leads across one of the other LED's. If your LED's are backward this test should light up the LED (assuming that LEd is not backwards itself, but you can try the LED both way's)


I know I've kid of babbled here, but I hope it helps anyway.
