Electronic Etch-a-sketch

thingiverse

Hi, Here's a brand new electronic game for my daughter inspired by the famous game Etch-A-Sketch. The left potentiometer controls vertical pitch and the right potentiometer controls horizontal pitch, while the red button clears the screen. Parts list: 1 arduino nano 2 linear potentiometers 100k 1 push button 1 little switch 1 lcd screen type nokia 5510 4 AAA batteries. All these parts were found on Ebay. I found them all on Ebay. Instructions Follow the schematics to wire your etch-a-rduino correctly. You have to download these libraries in order to use the nokia 5510 screen: -Adafruit_GFX.h https://github.com/adafruit/Adafruit-GFX-Library -Adafruit_PCD8544.h https://github.com/adafruit/Adafruit-PCD8544-Nokia-5110-LCD-library Here's the code: remove "" on the 4 first lines #include <Arduino.h> #define vertical A1 #define horizontal A0 // pin 8 - Serial clock out (SCLK) // pin 9 - Serial data out (DIN) // pin 10 - Data/Command select (D/C) // pin 11 - LCD chip select (CS) // pin 12 - LCD reset (RST) Adafruit_PCD8544 display = Adafruit_PCD8544(8, 9, 10, 11, 12); int valeurX =0; int valeurY =0; void setup() { pinMode(vertical, INPUT); pinMode(horizontal, INPUT); pinMode(2, INPUT_PULLUP); display.begin(); display.setContrast(50); display.clearDisplay(); } void loop() { valeurX = analogRead(horizontal) / 12.3; valeurY = analogRead(vertical) / 21.7; display.setContrast(60); display.drawPixel(valeurX, valeurY, BLACK); display.display(); if (digitalRead(2)==LOW){display.clearDisplay();} }
