Arduino and Potentiometer

This instructable gives an example of how to use an Arduino and a potentiometer

• Arduino UNO Board
• Potentiometer
• Base Shield
• USB Cable
• 4 Pin Grove Cable

• Connect the 4 pin grove cable to the potentiometer to your base shield in pin A0.
• Connect your base shield to the arduino board
• Connect the USB cable to the arduino and a computer (Mac of course)

Upload the file and open the serial monitor, it should look like the picture.

I´ve set the threshold to 400 you can change that if you want to.

If the potentiometer is below 400, the serial monitor will write a number followed by: brick REGISTERED: and how much below 400. The led on the arduino board will flash everytime the number is below 400

Try this yourself by adjusting the potentiometer

Good Luck!
