Hello all,
I recently picked up a tcrt1010 opto coupler and am having trouble figuring out how to make it function. The coupler has two pins for the IR led, and two for the photo-transistor's collector and emitter. I'm going to use the coupler for my rpm monitor project and I want it to output a 1 if it sees white, but a 0 when it sees black. There is only one circuit in this project and therefore the collector and led anode are connected w/ a resistor to vdd, (I think). What kind of resistances and stuff do I need to make it function in this way. The tcrt1010's datasheet is provided here: http://www.vishay.com/docs/83752/83752.pdf.
Thanks a lot,
