Opto-pi plugs directly into the 26-pin header on the Raspberry Pi, ... Opto-pi uses light to isolate the 8 digital GPIO pins. ... LED’s, etc.) to the Output pins.

A new Raspberry Pi case has been created to accommodate your bare Raspberry Pi mini computer board. Which has been laser cut from acrylic and even has light pipes fitted for you to be able to see ...

This is an idea for a RGB LED Magic Light Ball using a Raspberry Pi Pico. Hardware Setup. The schematic is quite simple. The entire setup is powered from a 1S (3.7V) Lithium-Polymer battery. A ...

X10’s are worthless noise plagued random event generators. A light or led and a photo resistor is the way to connect to the dimmer. High isolation and nothing on the outside covering the knob.

The Raspberry Pi 5 is a single-board computer about the size of a credit card. But like most Raspberry Pi devices, you can do even more with it if you’re willing to plug in an add-on or two. So while ...

The board that drives the Xbox 360’s status light ring also includes the RF module that wirelessly connects the controllers. He wired this up to his Raspberry Pi using the GPIO header.

Second, it has a 4-pin I2C connector instead of a 3-pin debug connector. And third, the BPI-Pico-RP2040 has an RGB LED light. Otherwise, the two boards are nearly identical.

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.

The Raspberry Pi board has a 40-pin GPIO header on it that needs through-hole soldering, along with bits like the Ethernet and USB ports. These require robust solder joints, ...
