The sensor sends “hit” signals to a small Arduino Uno via a PC817 optocoupler. The headcount is then displayed on a small LCD screen positioned above the speed bag, allowing you to keep track ...

These little Arduino boards are a real boon to amateur electronics tinkerers: cheap, versatile, and very small. This guy had the idea to make a high-speed ...

Why not create your very own high speed camera trigger using a Arduino, piezoelectric sensor (as a sound sensor), a DSLR camera and an external flash.

These days, most of us have a smartphone. They are so commonplace that we rarely stop to consider how amazing they truly are.

The 6mm-wide Optocoupler serves high-speed machine vision applications and quality testing with voltage conversion and isolation, as well as signal and level amplification. Initially a bespoke, ...

The FOD0721, FOD0720 and FOD0710 are logic gate optocouplers that isolate the logic control circuitry from the transceiver at the bus interface level. Since industrial systems are susceptible to noise ...
