In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

The Smart Circuits kit offers the best combination of educational instructions, easy-to-use pieces, and interesting projects that will grab and hold kids’ attention.

It is not only an extremely simple circuit, it also has the advantage of using only discrete components: a MOSFET, hall effect sensor, diode and two resistors, that’s it.

Today we announce the top winners and celebrate four score of entries in the Hackaday Circuit Sculpture Contest. Let’s take a look at twelve outstanding projects that caught (and held) our eye: ...

Try this project to build your own simple circuit and use it to test which common household materials conduct electricity. Background ...

The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach ...
