TTL Laser Retail

Story

SparkFun TTL laser and red laser with a microcontroller (eg Arduino) can be controlled by, or used as a stand-alone laser pointer is a simple to use. Laser can be great for many things; A receiver is an easy to use light for optical communication systems, everything from a cat toy.

In a wavelength range of 650nm red laser and a capacity of around 0.45-0.8mW common. This is enough energy to burn a hole in the wall, but it is not enough to shine in the eyes of the consumer.

Use

• On TTL laser, there is a polarization in connection with the 4-pin connector:
• Red wire - 5-12VDC input
• Black wire - ground
• Green wire - 10k pull-down (aka, GND)
• White wire - active low TTL input (3.3V or 5V logic)

Laser module, the basic operation is very simple. All you want to do laser power on the red wire and the black wire is connected to GND module launched a 5-12VDC power source, and then leave it. Then you connect the green and white wires together or unrelated to the green wire to the ground, leaving only the white cable connections. The laser will be turned on.

If you want to control the laser, you (including power and ground) is a TTL output on a microcontroller can connect to the white wire. Green wire can be left unconnected. Here's how you control an Arduino with the TTL laser:

Then all you need to do very basic "dance" sketch load. Your laser blinking per second, will start against 13-pin on the LED.
