A DIY stroboscope is a bright idea!

Arduino TeamSeptember 18th, 2018

Stroboscopes produce carefully timed pulses of light in order to make a rotating object appear still. While this may seem like something of an exotic concept, YouTuber Mr. Innovative decided to build his own using an Arduino Nano.

His project uses a PN2222A transistor to drive a 10W LED, which acts as the device’s light source. The spinning RPM is set via a potentiometer, and a small OLED provides user feedback.

As shown in the video below, the stroboscope is able to cause a sign spinning around on a fan to appear nearly stationary. If you’d like to create you own, Arduino code is available here.

    How do I get the schematic?

    Schematic without the advert links and maybe one that works would be great.
    Some of your YT links are a bit off.

    Collector and emitter are switched in the schematic presented in the video.
