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.
If you think back to your electronics I (or maybe II) class, you'll remember one of the really important properties of a voltage amplifier is that it barely loads your input—that is to say, it has an infinite input impedance.
In this tutorial, we'll create a very simple button-controlled blinking LED program using Embassy's async functions and task spawning, demonstrating how async/await syntax allows you to write concurrent code that appears sequential while the executor efficiently switches between tasks.
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.
For the budding Roboteer, learning how to add and control actuators is a key skill. In this guide, we are going to take a look at our servo driven Klaw actuator,* and show you how to control it via code.
