Figure 2 A circuit with an optocoupler (TLP621) which generates higher (even) harmonics that can be added to the original signal to achieve a tube-like sound. Transistor Q1 creates a current through ...

the output from the Arduino is the input to the circuit). Conversely, the comparator output and the connection to the Arduino’s analog converter (A0) are labeled nodes from the “Output and ...

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 ...

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 ...

Fig. 1 shows a diagram of a motor-drive circuit between a microcontroller unit (MCU) and an IPM. Seven units of digital optocoupler ACPL-W456 isolate the IPM's seven gate driver inputs ...
