« on: June 05, 2009, 02:04:17 AM »
Dear all,

I am building a line follower robot, I would like to use photodiodes instead of IR sensors in my design.Is this possible, a circuit will be great.

Thanks inadvance for your help

what "IR" sensors do you currently speak of?

I am not using any IR sensors at the moment. I am having a problem finding it. I want to use the photodiodes to detect the white from the black line.

I was thinking of building the same circuit. I found photo-diodes @ "All-Electronics" from Ledtech # LT4w55-2120.
