Build a Laser Tag Game

The Circuit Playground Express has a built in infrared (IR) transmitter and receiver. With a pair of Circuit Playground Express boards, you can send and receive messages that will cause the boards to run prepared operations. In this case, being "hit" with an IR blast causes the NeoPixels to count up from one to ten shots, and then score the final hit with an all red light fill and sound effect!

Play laser tag with a friend, or use it for target shooting. Too easy? You can also make it more of a challenge by adding a straw or empty pen barrel to cover the transmitter (TX) IR LED, thus narrowing it's cone of light.

Here's all you'll need:

2 x Circuit Playground Express
Super amazing microcontroller board stuffed full of sensors, inputs, and outputs!
2 x 3 x AAA Battery Holder
battery holder with On/Off Switch and 2-Pin JST
2 x USB cable
A/Micro B 3 ft.
3 x AAA Alkaline batteries
Three packs of two, for a total of 6 AAA batteries
