Arduino Digital Input: How to Use the Pull-Up Resistor!

Arduino Digital Input: how to use the Pull-up resistor!

In this video we're going to show you how to use the digital input of the Arduino board to control the LED illumination. We’re going to show this in two different ways: by using a switch and a button. We’re also going to explain the details of each command used in the code and how to use the pull-up resistor correctly. To build the circuit, we are going to use TinkerCAD software. If you have never heard about TinkerCAD have a look at our tutorial about how to use it on the link below:
