Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

The project is based on LM3915/LM3916 to produce a VU meter with the level indication using 10-segment LED bar graph. The VU meter circuit was built on a breadboard with a few components used such as ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for ...

As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

Words such as breadboard and prototype have an almost romantic allure in the electrical engineering world. Although the terms are sometimes used interchangeably, they are somewhat different: a ...

Looking for a fun and easy way to add a bit more interaction to your LED-laden projects? Why not turn them into proximity sensing LEDs? Our hacker, [Will], is just getting into designing his own PCBs.

As we are all coming to discover, there’s a lot more to breadboards than first meets the eye. For example, I just ran into a problem with one of my own breadboard-based projects that had me scratching ...
