I'm still completely new to this scene, and I was wondering if any of the old hands out there might be able to help me with figuring out what a couple of old sensors I just rediscovered in my junk bin might do. I'll try to post some pics, but in the meantime I'll just try to describe them... if they are what I want then I might be in luck for some free additions to yet another crappy robot!
First subject is this really cool looking curved piece of plastic with a little window I found, and it appears that it encloses a 3-piece setup consisting of a green LED, a photocell, and a red LED. The setup is arranged so that when they are in the enclosure, the two LEDs shine onto angled mirrors that are focused onto a convex lens (could be one-sided or double, I can't see the bottom) that in turn sits on top of the photocell. Light through the main window shines onto another angled mirror that also is focused on the photocell. The chip everything is attached to has 7 leads or contact points, or whatever you guys call female plug in receptacles... holes?
The chip itself has the following labels: LED502, K, PD501, 01, A, K, LED501, K, and it looks like the board itself is PF2171K255A and FH11938 PCB-AES (backwards rj looking symbol) AIN-34.
The other things I have are a million little beam-breaker or cliff type sensors consisting of a dark square LED and a clear LED... I understand how these work, but can they be angled in any way or used differently than just as two posts that need to be interrupted? I would love if I could somehow focus them to be forward looking distance or proximity sensors.
All of this stuff was out of a photocopier that someone gave me, full of stepper motors, sensors, and other weird things like solenoids and unknown styles of motors that sit on shafts. I literally have a pile of this junk now and I need to organize and purge.
I know I can just do some research on the net for this stuff, but I was wondering how real world applications have turned out, and specifically with the EZv3, and what pins I would connect to, what readings or values that might be applicable.
Thanks for any info in advance!
