Decoding Nerf LaserOps with Adafruit Circuit Playground Express #CircuitPlaygroundExpress #Adafruit @Adafruit @DefProc

Via defproc.co.uk, Patrick Fenner writes up his work decoding the infrared encoding on the new Nerf LaserOps line of gaming devices.

When the new Nerf LaserOps range came out in September 2018, I had a pair of blasters on the first day — because they seemed to be using targeted infra-red signals and that looked very hackable.

I had an Adafruit Circuit Playground Express from some teaching classes that we’d been doing recently, and the onboard infrared (IR) receiver and sender, plus the onboard RGB LEDs, looked like a nice way of duplicating the foam dart sensors but this time, for the new IR blasters.

Patrick states: a quick google found Chris Young‘s IR library for Arduino, and it is especially suitable because it has example Arduino sketches to show the raw timing of incoming signals — useful in this case because (spoiler alert) the Nerf LaserOps signal doesn’t use TV manufacturer codes for the blasters.

Using IRLib2 and decoding signals received on an Adafruit Circuit Playground Express, the encoding of the signals for three teams is discovered and can be detected. See the GIF above – great work!

You can download the code for this project on the DefProc GitHub repository. We look forward to further work on these!
