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.
In this tutorial, we'll provide a quick rundown of each part in the kit, to help reinforce your understanding of the component. For some parts, we'll include an example application, in case you're in need of a circuit to plug your new toys into.
The Qwiic Proximity Sensor is a simple IR presence and ambient light sensor utilizing the VCNL4040. This sensor is excellent for detecting if something has appeared in front of the sensor; detecting objects qualitatively up to 20cm away.
The Qwiic RFID ID-XXLA is an I2C solution that pairs with the ID-LA modules: ID-3LA, the ID-12LA, or the ID-20LA, and utilizes 125kHz RFID chips. Using the product's interrupt pin, we'll discuss how to get, store, and compare unique RFID IDs.
In this guide we will familiarize ourselves with the hardware, explain how to connect the display to your microcontroller of choice, cover how to install the Arduino libraries, and give an overview of the software examples that you can start off with.
