Using a Red Laser Diode Module with LDR for Laser Tag

Mario asks:

Arduino Compatible Photosensitive LDR Sensor Module Can you make it only detect the Arduino Compatible Red Laser Diode Module without it getting affect by natural light. My friends and I are building a simple laser tag game for our project. Thanks

thanks for your question Mario!

Most DIY laser tag systems use Infrared like this one.

If you’re intent on using a laser diode, you could modulate the laser so that it’s sending a repeating signal, such as in this tutorial.

Naturally we have
