Light Led

Language	English

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 onebox Schematic Program https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Processing/LEDButtonByOver https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Processing/LEDButtonByClick Note：Don't drop the picture in program 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: Video
