Once an electrical design engineer moves beyond initial conceptual sketches and delves into the core of the circuit design, incorporating digital isolators and optocouplers quickly becomes integral to ...

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 ...

Systems engineers have had to work around these limitations using external circuit components or by relaxing product specifications. New isolated digital input solutions (See ISO1211, ISO1212) are now ...

The circuit diagram of the digital frequency meter is shown in Fig. 3. It consists of Arduino Uno board, optocoupler MCT2E (IC1), 16×2 LCD and a few other components. The sinusoidal signal whose ...

In case the high voltage circuit induces an electrical surge, the surge remains only on the output side of the optocoupler, and the circuit at input side remains safe ... barrier between ...

The concept behind a pushbutton is that when the button is pushed, it connects two points on a circuit ... involves both digital input and digital output and you'll use a pushbutton and LEDs. Arduino ...

And while simple on-off control of a device through an optocoupler ... circuit is required, there’s one more missing ingredient: the amount of light the LED puts out per milliamp of input ...

The author proposes an optically controllable negative-resistance circuit constructed with optocouplers. The breakover voltage and the holding current of the negative-resistance characteristics can be ...

The isolated analog input module presented here is particularly suitable for industrial electronics applications. Sending analog signals from field sensors over long-distance cables is often difficult ...

These Arduino scripts ... are for the LED (basic) Circuit and the Audio Circuit, respectively. The rest are for custom circuits and inspiration for further projects. Creates various sounds, selected ...
