A bright lamp flashes in synchrony with the lightning bolts, indicating the proximity and intensity of the storm. The described circuit operates as a storm warning system, utilizing a bright lamp to provide visual alerts in response to lightning activity....
This circuit serves as the foundation for the dimmers in a model theatre lighting system that utilizes touch globes as the light source. It is centered around a 555 timer, which drives a Triac. All dimmers operate from a...
In this circuit, light causes R5 to conduct, forward-biasing Q1. R6 sets the sensitivity. SCR1 is triggered by the emitter voltage on LQ1, sounding the alarm bell. When S1 is pressed, SCR1 unlatches. It is important to ensure that...
The circuit utilizes relay control. The voice switch operates as follows: upon the first clap, the load (lights) is activated; upon the second clap, the load (lights) is deactivated. This system can be employed to control lighting in residential...
Disco anyone? Actually, this strobe serves a much more useful purpose than making it look cool when you dance in the dark. You can use it to view fast-moving objects, look for cracks in PC boards (hold the strobe...
This circuit diagram illustrates a light-activated switch utilizing the National Semiconductor comparator IC LM311 and a light-dependent resistor (LDR). The configuration is based on a voltage comparator circuit centered around IC1. The non-inverting input of IC1 receives a reference...
