To learn more about the Raspberry Pi port HAT project play the promotional video below. “Raspberry Pi can read 26 Input signals through the GPIO header, but sometimes you might need to read more.

The folks at Raspberry Pi have announced a new touchscreen component for people using boards to create miniature touchscreen ...

You can easily upgrade various features and tech in your bedroom by using Raspberry Pi, if you have the coding know-how. Here ...

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.

In addition to being a serviceable single board computer, the Raspberry Pi also has a header full of GPIO pins at your beck and call. [Tedbot] sent in a great tutorial on using these pins with ...

One of the biggest draws of the Raspberry Pi family of single board computers or SBCs is their expandability. That comes via the standard 40-pin GPIO header on the full-sized boards.

Unfortunately, that guide didn't exist when I first wanted to do this, so instead I had to piece together what to do (specifically which GPIO pins to connect to which pins on the clip) by combining a ...

Of course, the Pi’s GPIO pin’s aren’t long enough to efficiently transmit at 304.2 MHz, so [River] added a proper antenna, as well as a low-pass filter to clean up the transmitted signal.

While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.
