Objective

This tutorial will teach you how to use the potentiometer to control Processing, then to control the movement of smile face on screen.

Equipment

• Microduino-Core
• Microduino-FT232R

• Other equipment
  • USB cable one
  • RGB LED one
  • 330Ω resistor one
  • Bread one
  • Breadboard Jumper onebox

Debug

Step 1：Set up hardware system, as follows:

Step 2：Explain the code:

//Read potentiometer's simulation value, and assign values to the smiling face of the x coordinate values

 void draw() {
   sensorValue = arduino.analogRead(potPin); //Reading the value of the potentiometer
   background(255);
   image(face,sensorValue,80);
 }

Step 3: Compile the code and download it.

Step 4: After running, a smile face will display on the left side, rotate the potentiometer and then observe the smile face's change.

Result

The smiling face on the screen will move around with the potentiometer's rotation, as follows:
