Tired of loud TV ads? In 2012, Peter de Bruijn built the Mini-Mute — a clever circuit that let him mute his TV with a simple ...

Relays are devices which allow low power circuits to switch a relatively high Current and/or Voltage on/off. Here is a simple microcontroller-relay interface circuit with perfect “galvanic isolation”.

Chris Gammell wants to know: What’s in your circuit toolbox? Personally, mine is somewhat understocked. I do know that in one of my journals, probably from back in the 1980s, I scribbled down… ...

The Department of Electronics at The Bhawanipur Education Society College (BESC) is gearing up to spark fresh academic ...

If you’re really clever, you can clock digital circuits with mains AC, but we’ve never seen someone replace a tiny crystal in a microcontroller circuit with mains power.

Geneva&#151An in-circuit emulator for the ST72561 family of 8-bit microcontrollers performs real-time emulation, debugging, and in-circuit programming while touting the emulator family's low-cost ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

For over 30 years scientists at Fraunhofer IMS in Duisburg have been dealing with the development of microelectronic circuits, electronic systems, microsystems and sensors. Because of its ...
