LED Gumball Machine

Turn a large voltage into a smaller one with voltage dividers. This tutorial covers: what a voltage divider circuit looks like and how it is used in the real world.

Learn the difference between 3.3V and 5V devices and logic levels.

Learn about the common data types and what they signify in the Arduino programming environment.

Let's have some fun with LEDs! We'll explore LEDs once again with the SparkFun RedBoard Qwiic, making cool effects, and putting those effects to work using a sensor.

The Qwiic Pro Kit was designed to allow users to get started with Arduino without the need for soldering or a breadboard. We've included three inputs (a joystick, accelerometer, and proximity sensor) and one display that can be daisy chained to the RedBoard Turbo (SAMD21) Development Board.

Running low-power machine learning examples on the SparkFun Edge can now be done using the familiar Arduino IDE. In this follow-up to the initial Edge tutorial, we'll look at how to get three examples up and running without the need to learn an entirely new SDK.

Sometimes we want to do more with our data than just watch the values roll by on a screen. In this tutorial, we'll take a look at one way we can translate that data to movement.
