I have been meaning to design a robot which basically avoids obstacles. So I decided to make a IR sensor and brightness sensor. Attached is a written step by step process of designing a IR sensor that would be remain turned on when no obstacle is in front and will turn off when an obstacle is detected. The blue LED is a general purpose Led to visually show how the circuit performs.
I have covered the IR led and the IR phototransistor with heat shrink tubing to make it less susceptible to ambient light.
This procedure will come in hand if someone else also decided to make one.
Please comment
