Objective This tutorial will control 8 LEDs via Processing. Equipment Microduino-Core Microduino-FT232R Other equipment USB cable one LED one 330Ω resistor one Bread one Breadboard Jumper onebox Schematic 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. Video
