Tonight’s Maker Club: Arduino is full, but you’re welcome to stop into the library to use our Arduino Uno for free. Everything in this kit is included. Just ask the friendly staff at the Reference Desk, and bring an ID with you.
What’s an Arduino? It’s a microcontroller board—part of a computer (unlike a Raspberry Pi, which is a fully functioning computer. Some may argue that a microcontroller fits the definition of a computer, but for simplicity’s sake, we’ll define “computer” in the common usage as a desktop or laptop). You’ll need a "real" computer to program the Arduino with the free Arduino IDE—software that lets you type code, then upload it via a USB cable to the Arduino board itself. After that, you won’t need the computer anymore, because as long as the Arduino has a power supply, it can run that code indefinitely. Watch this Make video on the Arduino here!
