The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

Not if you’ve watched [0033mer]’s Simple Electronic Circuit Hacks video! You know just what to do. The ground pin of a LM7805 connects to the cathode of a TL431 programmable Zener diode pulled ...

So, I'm pretty handy with a soldering iron to put together stuff, but I have little to know idea of how to go about figuring out how to build a circuit. I mean, I know what a resistor does, and a ...

It's really surprising: it turns out that among simple electronic circuits, built of just a few components, many of them behave chaotically, in an extremely complicated, practically unpredictable ...

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 ...

This simple electronic bicycle horn circuit uses only one gate of a 4093 quad 2-input NAND Schmitt trigger, U1, conected in a simple, low frequency, square-wave oscillator circuit. The oscillator’s ...

I learned some basic electronics in high school physics class: resistors, capacitors, Kirchhoff’s law and such, and added only what was required for projects as I did them. Then around 15 yea… ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more ...

A simple circuit uses one control device to control bass and treble simultaneously, with a symmetric response that is flat at the center of the adjustment range. Derek Bowers >> Electronic Design ...
