This is a video tutorial about DC motor speed controller using power op-amp. This video shows how to control dc motor speed using power op-amp. In this video the op amp is configured in non-inverting configuration. When the power supply is on, the LED will on and when the potentiometer is turned, the speed of dc motor will gradually increase. […]

This is a circuit of Voltage-to-Pulse Duration Converter. This circuit is used to convert voltage into pulse duration by combining a timer IC and an OP Amp. This circuit can obtain accuracy up to better than 1%. The output signal is independent of the input voltage and still retain the original frequency. Here is the circuit: [Source: Philips Semiconductors Application […]

This is a Long Time Delays using 555 Timer. In 555 Timer, a function of charging rate of the external capacitor is the timing. This circuit needs expensive capacitors with extremely low leakage. Practically, the components limit the time between pulse to around twenty minutes. To get longer time periods, we can connect both halves in tandem with a “divide-by” […]
