Keyes Arduino laser transmitter module

Product Features:

• Dot laser
• Operating voltage 5V
• Power 5Mw
• Wavelength 650n m
• OD 6mm

1. This 5V laser head very easy to use, you can use Arduino control, do controllable laser pointer, theft detection, etc. interesting application devices.
2. Whenever the laser can not point to themselves or others eyes, even if the case is closed the laser will have to open the possibility of error.
3. This laser is not a toy. Do not give children.
4. The user of lasers should wear special goggles, for the invisible laser, this point is particularly important.

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 }
