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.
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 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 ...
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 ...
He is using the ServoBlaster package to drive the servo motor with the Raspberry Pi GPIO pins. That’s all fine and good by itself, but he went the extra mile and designed a few different levels ...
At first glance, using a microcontroller for a simple fancy light project is overkill. However, the existing design can be modified later without additional hardware. Often a few extra code lines will ...
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.
This Raspberry Pi project visualizes CPU usage with LED light show. A Blinkt module displays green under low load, red fast under high, lilac at 100%.
Other features of the Raspberry Pi 500 computer keyboard include an 800MHz VideoCore VII GPU, a 40-pin Raspberry Pi GPIO connector for attaching peripherals, support for 802.11ac Wi-Fi and ...
An automated dab'll do ya Raspberry Pi cuts product returns by 50% by changing up its pin soldering Combining both the big and little solder jobs made a big difference.
