The Raspberry Pi takes 5 volts to run, and you can connect it directly to the GPIO (general purpose input/output)—the 26 pins next to the yellow video out socket (shown above).

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the ...

Set up and configure your Pi If you have just bought your Raspberry Pi, this command is one of the first tools you’ll use to set it up. To use it, open the terminal and run 'sudo raspi-config ...

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.

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.

To test the motor control I used the mapping of the GPIO pins to the file system directory /sys/class/gpio. Each GPIO can be controlled here once the pin is exported. Commands can then set pins ...

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 ...
