Here’s how you can remotely control a Raspberry Pi 5 using a smartphone and Bluetooth low energy.

There’s currently a significant amount of confusion around the full extent of the GPIO hardware issue in the Raspberry Pi RP2350 microcontroller, with [Ian] over at [Dangerous Prototypes] of … ...

Most GPIO capabilities become user-friendly by code libraries written to simplify options, but some simplifications are built right into the Raspberry Pi GPIO pins themselves.

GPIO programming on a Raspberry Pi using Arduino's Web IDE - this post brings Raspberry Pi and Arduino together.

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.

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.

“ZYMKEY4i is the fourth generation of the Zymbit security module designed specifically to work with Raspberry Pi. It connects to the GPIO header of the PI and uses the I2C bus and GPIO-4 to ...
