A GPIO pin, such as the 17 out of 26 pins on the Raspberry Pi B’s board that are programmable switches, works in binary mode. Binary is just a fancy way of saying “on” or “off”. That’s how digital ...

The movie time circuits were colored gels, and wouldn’t exactly be practical for a Raspberry Pi-based prop. It’s a great build, and one that would look great in either a ’98 Nissan Altima or ...

Hot Wires / Snap Circuits are simple circuit building blocks that are used to teach electronics to small children. They use press studs, similar to those used on coats, to connect the components, ...

UK national treasure the Raspberry Pi Foundation has announced the Raspberry Pi 5, its latest circuit-board computer. The Raspberry Pi 5 starts at £59.30, and is available to pre-order now.

The newer version of the circuit adds a high-speed buffer chip to provide a lower-impedance source, and tweaks the filter values somewhat. The audio circuitry from the Raspberry Pi 3.

Raspberry Pi Pico, based on chip RP2040, is an easy-to-use development microcontroller board that can provide flexible input/output functions and meets the teaching needs of basic electronics to first ...
