Ky-008 Laser Module

Ky-008 Laser 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

wiring pastikan benar, S jika terkena 5V langsung mengakibatkan mati pada modul

Contoh program

 _Wink

 This example code is in the public domain.

 Originally Mega analogWrite() test

 This sketch fades LEDs up and down one at a time on digital pins 2 through 13.
 This sketch was written for the Arduino Mega, and will not work on previous boards.

 The circuit and sketch were written by Tom Igoe for the Arduino Mega, but I changed it
 to an Arduino Uno as a single Laser.
