Here’s a Raspberry Pi hack that adds web control using PHP and MySQL. As you can see in the image, it serves up a webpage (using the Apache2 server) which allows you to change the state of th… ...

For the lucky few who have a Raspberry Pi board in their hands, you can now use the GPIO pins as a web interface (German, google translation). [Chris] is turning this magical board is turning a ...

With Opto-pi, there is not an electrical connection between the Raspberry Pi and connected loads (motors, relay coils, etc.) or input signals. Opto-pi uses light to isolate the 8 digital GPIO pins.

I always like projects that bring the Raspberry Pi and Arduino together, however gently. It's what the world needs, a bit more harmony. Check out this little one on GPIO programming on a Raspberry Pi ...

The Raspberry Pi camera board transfers data through an extremely fast camera serial interface (CSI-2) bus directly to the system-on-chip (SoC) processor. It does this through a 15-pin ribbon cable, ...

When it comes to pricing, the Raspberry Pi 5 will only come in two variants — one with 4GB of RAM for $60 and an 8GB version for $80. The entry price is much more expensive, but the Raspberry Pi ...

In addition to the SoC, there is a second chip on the Raspberry Pi 5 board: The new RP1 I/O controller developed by the Raspberry Pi Foundation takes care of controlling the SD card slot, the USB ...

One of the Pi’s most exciting features is the GPIO header. It allows you to interface with LEDs, sensors, motors, and other hardware for a wide range of cool automation projects.
