Strobe Light Circuit Diagram and Explanation: The complete circuit diagram is shown in the above image. You can either build them on a breadboard or solder them to a Perf Board. The explanation of the ...

Light operated switch circuit The sensor is a light-dependent resistor (LDR) made of CdS semiconductor whose resistance changes with light. In the presence of light its resistance becomes low, while ...

There are a wide range of applications for light sensitive switches: lighting, entrance door, automatic staircase, automatic opening of doors to the action of a ray of light, alarm systems, etc… Many ...

This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

This light activated remote switch circuit comes with a significant though small current drain in order of 15mA and must be turned off while not in use. On the other hand, when using the CMOS timer ...

Automatic off timer circuit The collector voltage of transistor T1 goes high to light up LED2 (indicating that the timer circuit is enabled) and transistor T2 starts conducting. As the collector ...

The main part of this LED chaser circuit diagram is 555 timer IC which generates some variable frequency. 555 timer IC is a general purpose IC which can be configured in some different modes like ...
