If you are an RC modeller, then this circuit is for you! The compact RC Switch let you turn something on and off from a regular R/C channel. The device is powered entirely by the receiver, drawing ...

Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

In the 120V circuits of homes and offices, the grounded conductor is the same as the neutral. Typically, when wiring a switch for a 120V load (e.g., a light) only one wire comes to the switch and only ...

Experimenting with batteries, bulbs, buzzers, switches and other electrical components is a great way to learn about circuits and start to think about how to incorporate sounds into your Build a ...

Archaic light switches might as well be from the stone age. All they do is turn a light on and off. They can't dim lighting gently or remember the brightness level you prefer. Outdated switches don't ...

Integrated circuit technologies are enabling intelligent, chip-based, optical packet switch matrices. Rapid real-time re-configurability at the photonic layer using integrated circuit technologies is ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
