The KY-008 Laser transmitter module consists of a 650nm red laser diode head and a resistor. Handle with caution, do not look directly into the laser head.
|Operating Current||less than 40mA|
|Working Temperature||-10°C ~ 40°C [14°F to 104°F]|
|Dimensions||18.5mm x 15mm [0.728in x 0.591in]|
KY-008 Connection Diagram
Connect signal (S) to pin 13 on the Arduino and ground (-) to GND. Middle pin is not used.
This Arduino sketch will repeatedly turn on and off the laser head every second.
