PROJECT – Traffic Light In this tutorial you will learn how to make Traffic Light with Arduino. STEP – 1 Components Components Required:- 1. Arduino Uno 2. Breadboard 3. 3 LED 4. 7 Segment 5. 3x 220Ohm resistors,1 1KOhm Wires . STEP – 2: Circuit The connections are pretty easy, see the image above with the breadboard circuit schematic. STEP – 3 : Code int displayPin[] = { 2, 3, 4, 5, 6, 7, 8 }; #define GREEN 11 #define YELLOW 12 #define RED 13 // define digits segments int digit[10][7] = { { 1, 1, 1, 1, 1, 1, 0 }, // 0 { 0, 1, 1, 0, 0, 0, 0 }, // 1 { 1, 1, 0, 1, 1, 0, 1 }, // 2 { 1, 1, 1, 1, 0, 0, 1 }, // 3 { 0, 1, 1, 0, 0, 1, 1 }, // 4 { 1, 0, 1, 1, 0, 1, 1 }, // 5 { 1, 0, 1, 1, 1, 1, 1 }, // 6 { 1, 1,
PROJECT – LED MATRIX In this tutorial you will learn how to use LCD with Arduino and display some text on the LCD. STEP – 1 Components Components Required:- 1. Arduino Uno 2. Breadboard 3. LED MATRIX 4. Wires. STEP – 2: Circuit The connections are pretty easy, see the image above with the breadboard circuit schematic. STEP – 3: Add Library Before you can use the LED Matrix on the Arduino, you’ll need to install the library. It’s easy to install, open up the Arduino IDE. Then go to Sketch>Include Library>Manage Libraries>search LEDCONTROL>install LEDCONTROL library. STEP – 4 : Code #include "LedControl.h" #include "binary.h" /* DIN connects to pin 12 CLK connects to pin 11 CS
