- Hi, I'm Mark Niemann-Ross and welcome to this week's edition of Raspberry Pi Weekly. Every week, we explore the Raspberry Pi and share useful tips. Remote GPIO allows one Raspberry Pi to control the GPIO pins on another Raspberry Pi. It also allows a standard laptop to remotely control the GPIO pins on a Raspberry Pi. There are ways to do this without remote GPIO but you may have a specific need for this technology. So let me show you how to set up remote GPIO and how to make it work. Setting up a remote GPIO requires a couple of steps. There are different ways to do this. I'm going to show you the quickest. Before turning on the Raspberry Pi, build a simple LED circuit shown here. It's the identical circuit we built before. Connect one leg of the LED to ground on pin 39 and the other to GPIO 26 which is also known as Raspberry Pi or pin 37. If you need to check the polarity on the LED to make sure it'll…
