Mains Light dimmer

Audio light modulations add to the enjoyment of music during functions organised at home or outdoors. Presented here is one such simple circuit in which light is modulated using a small fraction of the audio output from the speaker...

Figure 2-39 illustrates a typical application circuit for the JS88 manifold, which includes an oscillation resistor (R) that allows for fine-tuning of the water flicker frequency. When switch (S) is closed, components L1 to L5 sequentially output low signals...

The use of white LEDs for home illumination is gaining popularity due to their high power efficiency. The diagram illustrates a simple circuit configuration that consists of multiple LEDs arranged in both series and parallel. In the LED tube...

This circuit is permanently connected to a mains socket and is designed for trickle charging nickel-cadmium (Ni-Cd) batteries. In the event of a power outage, the lamp automatically turns on. An alarm sounder can be used in place of...

This circuit illustrates an automatic room light circuit diagram. It features a small memory component that allows it to automatically switch on and off. The automatic room light circuit is designed to enhance energy efficiency and convenience by utilizing a...

This light-sensitive automatic light switch circuit is designed to be connected to the main 220V supply. The circuit will activate a 220V lamp during nighttime. The light-sensitive automatic light switch circuit operates by utilizing a light-dependent resistor (LDR) to detect...
