Do you need an LED? The answer is always yes. But what if you need one right now? Build yourself an LED gumball machine and never run out again!

Control the RedBot wirelessly based on the movement of your hand using an accelerometer and XBees!

In this guide, we will cover how to utilize the RedBoard Turbo to emulate an HID keyboard that responds to inputs from the Qwiic Keypad to create your own custom shortcut keypad.

The goal of this project is to have a website hosted on an ESP32 that controls any relay-controlled device connected to a local network and keeps a dynamically updated state of those devices.

Pulling the plug on your Raspberry Pi before it safely shuts down... is a bad idea! This can result in a corrupt microSD card and file system. Normally, we can use the menu bar from the GUI or type a command in the terminal window to safely shutdown the Pi.

This tutorial covers how to get CO2 and other environmental readings from the STC31 using both Arduino and MicroPython when connecting the CO2 Sensor Breakout to a compatible development board over Qwiic.
