Arduino Mega 2560
Optical gates are basicly an infra LED and photo sensor facing eachother. If infrawave is sensed then the optical gate is open. It is closed otherwise. If everything functions normally a closed optical gate means something is blocking the space between the infra LED and photo sensor. They are widely used for counting objects.
Required hardware
- Arduino Mega 2560
- Optical gate
- Resistors: 100Ω, 100kΩ
