Remote Controlled Power-Off Switch Circuit The circuit consists of a timer IC NE555, a decade counter IC HCF4017, three BC548 transistors, an infrared (IR) sensor IC TSOP1738 and a few discrete ...

The 38kHz infrared rays generated by the remote control are received by IR receiver module TSOP1738 of the circuit. Pin 1 of TSOP1738 is connected to ground, pin 2 is connected to the power supply ...

Remote control tester circuit When no signal is sensed by the sensor module, output pin 2 of the sensor goes high and, as a result, transistor T1 switches off and hence LED1 and buzzer BZ1 go off.

The circuit uses a Vishay V34836 infrared receiver to pick up the invisible signals that are sent from a remote control. A Microchip 12F683 processes the data and has two main output modes.

In the field of power electronics, modelling circuits with controlled switches is crucial for understanding and optimizing their performance.

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two ...
