Objective

This tutorial will teach you how to use the Processing to light LED.

Equipment

• Microduino-Core
• Microduino-FT232R

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

Debut

Step 1: Set up hardware system, as follows:

Step 2: Explain the code:

// Declaring two variable of type PImage, a class available to us from the Processing core library. PImage LEDON, LEDOFF;

//load two img LEDON = loadImage("LEDON.png"); LEDOFF = loadImage("LEDOFF.png");

Mouse movement will light the LED which was realized in LEDButtonByOver.

Mouse over:

 // When the mouse is moved, the state of the button is toggled. 
 void mouseMoved() {
   if (mouseX > x && mouseX < x+w && mouseY > y && mouseY < y+h) {
     button = true;
   }  
   else {
     button = false;
   }
 }

Mouse click will light the LED which was realized in LEDButtonByClick.

Mouse Click:

 // When the mouse is pressed, the state of the button is toggled.   
 void mousePressed() {
   if (mouseX > x && mouseX < x+w && mouseY > y && mouseY < y+h) {
     button = !button;
   }  
 }

Step 3: Compile the code and download it.

Step 4: After run, mouse move or click the LED, observe the result.

Result

Mouse move on the LED, it will light, and trun off when leave it. Processing'S animation effects:
