Introducing Arduino UNO
Meet your microcontroller!
“Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. “ – Learn more from the Arduino Guide
For examples and inspiration check out the Project Hub.
That white thing attached to your UNO? Its a solderless breadboard!
Breadboard make it easy to create circuits without soldering any wires together. The connection is made by inserting wire into the tiny holes:
- Each pin hole on a
Railis connected vertically.
- Each pin hole in a
Rowis connected horizontally.
Splitruns down the middle dividing the board in two.
Inputs & Outputs
Arduino is designed to make interactive projects. This means it uses sensors to get input from the world, and responds by controlling actuators / outputs. Uno does not have any built in sensors or actuators, you connect them to the boards pins.
- potentiometer (dial)
- temperature sensor
- accelerometer (motion sensor)
- photoresistor (light sensor)
- LED (light)
- piezo buzzer (sound)
- Servo motor, DC motor (motion)
