IR LED controll 555/556 timer IC

I'm using a 556 IC to generate a carrier wave and a slower pulse wave, which is detected by a detector connected to an arduino. The arduino counts pulse lengths, and by varying pulse length, the arduino should be able to distinguish between several similar bases running at different pulse frequencies.

You are retarded

If your numbers are indeed microseconds, then there are, by definition 1 million of them per second. If I was reading your screen shots correctly, it appeared that they were in the tens of thousands, roughly 41000 to 71000. Now 1000 microseconds is 1 millisecond, or 1/thousandth of a second, therefore you were reading roughly 41 to 71 milliseconds. Hope this helps. BTW, good job on the breadboarding. Keep up the good work and have fun. JAC

dont call it Led, it sounds stupid. call it L-E-D

Hi, I'm very interested in doing this type of work for a living, after college. This may be sort of random, but what type of courses have you received to learn this type of thing? I'm currently an electrical engineering major and a lot of my electrical knowledge is self-taught (random books and articles that i picked up along the way). Thanks for whatever help you can offer. -Joe
