Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

The flip-flop, aka latch, can also be understood as Bistable Multivibrator as two stable states. Generally, these latch ...
