Look closely at the colored pixels on this pair of 8×8 RGB LED modules and you’ll be able to pick out some of the familiar shapes of Tetris pieces. It’s impressive that [Jianan Li]… ...

Usually, the common anode of the LED package is the second pin from the flat side of the LED package. It is also the longest of the four leads. This lead will be treated as the “common” pin of the RGB ...

Recently I walked a newcomer to electronics through a circuit as I recreated it on a breadboard from a schematic diagram. He could see the components go into the breadboard, help identify the ...

He decided to build some simple, modular circuits on protoboard and make them easy to interface with the breadboard. As you can see, he ended up with seven modules that make prototyping faster and ...

PCB design is easy, right? To a certain extent that’s fair to say; with a growing number of schematic design and PCB layout packages available — normally integrated, increasingly free — almost anyone ...

The PCB Direct virtual breadboard has been created to allow anyone to create interactive virtual breadboard circuits for platforms such as Arduino, ARM, PIC, Raspberry Pi and more, ...

Circuit Scribe is a rollerball pen that draws with conductive silver ink –no annoying breadboards involved. In fact, you can build a circuit with nothing but a coin, battery, paper clip, and LED.
