Arduino Workshop - Project 05: Push-On, Push-Off - Part 2

Hardware Required: Arduino Uno board LED (x2) 330 ohm (x2), 10 K ohm resistors Pushbutton switch (N.O.) jumper wires

Schematic:

Project Steps: Assemble an LED and pushbutton, following the directions for project 4. Add a second LED: Insert a second LED in the breadboard Connect a wire between the ground and the short pin of the second LED Connect a 330 ohm resistor between the D12 on the Arduino and the long-leg of the LED Change the program to turn LED2 on when LED1 is off, etc.. Save a copy of the Project4 code as a Project4b (file, save-as, enter new name) Change all of the "LED" variables to "LED1" Copy each line containing "LED1" and paste as a new line immediately following it. Change "LED1" in each of the duplicate lines to "LED2", for example: const int LED1 = 13; const int LED2 = 13; Change the Digital Output used for LED2 to 12 (const int LED2 = 12;) Change the lines that turn LED2 on and off to the opposite of what LED1 has: digitalWrite(LED1, HIGH); digitalWrite(LED2, LOW); Verify your code and upload to the Arduino.
