I have found myself a really nice scheme of buzzer that is controled by the IR led and photodiode by I wonna upgrade it so it can use for controlling servo. What I have in mind is that when there is no object the servo whould stand still and when object comes by he will go for 90 degrees wait for 5 sec and go back to 0 position. I just wonna know is that possible for Arduino starter and where should I look for help. Thanks.
