Arduino code and video Transmitter and Laser Sensor

دروس آردوینو به فارسی

This is the Arduino code and video for Laser Sensor Module

In this tutorial we lear how to use Laser Transmitter (TX) and laser receiver (RX) so crease to turn ON or OFF something from far distance of up 50m. If you can aim it, it might work up to 200m.
Receiver operating current at 5V: 2.5mA
Transmitter operating current at 5V: 28mA
