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 ...

For example, I used the output signal of the proximity sensor to trigger my old wireless doorbell thru an optocoupler after modding the cordless bell push switch circuitry (which will possibly put in ...

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 ...

The FOD8160 high-speed logic gate optocoupler in the new wide body 5-Pin SOP is part of Fairchild's high performance optocoupler family and offers superior switching performance, low power ...

San Jose, Calif. Avago Technologies said it has introduced the industry's fastest 3.3-V/5-V optocoupler that is capable of transmitting data at 25 megabaud (MBd). The high-speed optocoupler also ...

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 ...
