The Video

(its mainly for entertainment but I do explain a bit)



The idea was for comedic purpose but for those interested on how this build was made. Id say the build is very easy the only unique I did was add the handle from a small flashlight to give a narrow sight instead of a wider view(shown in video) that a PIR sensor usually gives. All powered by a portable charger.

Some advice do not buy mp3 modules off amazon or bang good just get it off the actual website. Learn from my mistakes.

you can move around the sensor output and make sure to change audio files to mp3 or wav
