5.  Push-buttons and Sensors

In this section you’ll learn how to program and use Push-buttons, sensors, and LEDs.

5.1. 

Connecting an LED

You’ll need to use an LED, so go ahead and plug one into connector 

A4

 on your Studuino.

5.2. 

Push-buttons

You can find the Push-buttons right on your Studuino. They’re assigned to connectors A0-A3.

Keep an eye on your cables!

The gray wire should be on the inside.
