This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...

If you want to easily control the power in a circuit, you’ll probably reach for the classic toggle switch. While there’s certainly nothing wrong with that, physical toggles are a bit dated at this ...

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

There are as many varieties of smart light switches (and dimmers) as there are light bulbs, and while the prospect of upgrading your old dumb switch might seem daunting, they’re usually pretty simple ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the circuit ...

Working on an embedded project? An 8-bit microcontroller with a pulsewidthmodulation (PWM) peripheral can provide a low-cost and easy solution to adding natural voice to your next embedded endeavor.
