It’s late at night. The solder smoke keeps getting in your tired eyes, but your project is nearly done. The main circuit is powered by your 13.8 V bench supply, but part of the circuit needs … ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

This simple and cost-effective ding dong electronic doorbell circuit is based on IC 8021-2. The IC has an in-built circuitry to produce ding dong sound each time its pin 3 is pulled low. The sound is ...

Learnabout Simple Electronics has been out of print for well over three decades now, but if you want a copy you should be able to find it in second-hand book stores online.

The projects we tried took the kids between 15 seconds (to build a simple circuit) and four minutes (to build a push button). These times felt short, but the kids on our first test panel liked how ...
