Few realize how close an optical coupler resembles a relay. It is so close, in fact, that one can be wired as a Run-Stop latch circuit. One advantage over ...

Here Arduino is used to generate the PWM pulse, which takes the input from the potentiometer and gives PWM signal output to TRIAC and optocoupler circuit which further drives the AC fan at the desired ...

The circuit was designed to formulate a timer that can provide an alert method with the use of a buzzer while the presence of the optocoupler will make it possible to drive an external circuit.

Overvoltage Protection Circuit Diagram The circuit’s dual power supply using transformer X1 and diodes D1 through D4 isolates the supply between relay RL1 and control circuitry with the help of ...

So here is the simplest way to control most of your home appliances, without getting up and moving to the switchboard, through Arduino. How to Automate Your Home Appliances using Arduino? Now let’s ...

As [Mic] often got requests to make high-power switching boards, he recently finally gave in and designed the one shown above based around a solid-state relay. Some of our readers that already play… ...
