Free electronic circuit design and schematic diagram
Interfacing high power load can be done in many ways, such as using voltage divider resistors, transformer, or optocoupler. In the circuit shown below , an optocoupler method is presented. This optocoupler serve the logic level translation with flexible input, accepting wide range of voltage level, which is suitable for many high power load/devices. To couple a high-voltage load to […]

This schematic diagram shows a circuit of basic logic gate circuit. This PNP transistor circuit can act as OR gate or AND gate. If the input is closing of switch, this circuit acts as AND gate. This circuit acts as OR gate when the input is opening of switch. The phase inversion of input does not complicate overall circuitry. Here […]
