==Program==

https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Processing/sketch_8LEDs

Note：Don't drop the picture in program

==Debug==

Step 1：Set up hardware system, as follows:

Step 2：Explain the code:

There are two code files in this example:

LED object：

//Define the variable in object
int xpos;
int ypos;
int w = 50;
int h = 50;

PImage LEDState=loadImage("LEDOFF.png");
int ledPin;
boolean button = false;

//Constructor function
LED(int xpos_, int ypos_, int ledPin_) {
xpos = xpos_;
ypos = ypos_;
ledPin=ledPin_;
}

//Display function
void display() {
if(button) {
LEDState=loadImage("LEDON.png");
} else {
LEDState=loadImage("LEDOFF.png");
}
image(LEDState,xpos,ypos);
}

sketch_8LEDs：Main function

//Mouse click function, identify which LED was clicked, then change the button state and LED state after click.
void mousePressed() {
for (int i = 0; i < leds.length; i ++ ) {
x=leds[i].xpos;
y=leds[i].ypos;
w=leds[i].w;
h=leds[i].h;
if (mouseX > x && mouseX < x+w && mouseY > y && mouseY < y+h) {
leds[i].button = !leds[i].button;
}
}
}

Step 3: Compile the code and download it.

Step 4: Click several LED randomly, observe the result.

==Result==
8 LED will be displayed in screen, you can cotrol them.
