KEYES ARDUINO laser transmitter module

Laser transmitter module, 650 nm (red), gives a small intens beam. Take care of your eyes, do not look direct into the beam.

Power consumption: 30 mA at 5 V

Pin layout

The module is labeled wrong, see below !!

• Pin - = GND
• Pin (middle pin) = not connected
• Pin S = +5V

Routines source code:

void setup ()
{
   pinMode (13, OUTPUT); // define the digital output interface 13 feet
}
void loop () {
   digitalWrite (13, HIGH); // open the laser head
   delay (1000); // delay one second
   digitalWrite (13, LOW); // turn off the laser head
   delay (1000); // delay one second
}
