Learning : Arduino Projects, Arduino Coding, Electronic Circutes
Subject: First Application, Light the LED
[NOTE: We are working on Electronic Devices, Voltage, Resistors and other Electronic Parts that may Become HOT due to un-stable current or Wrong Wire Connections.. PLEASE BE CAUTIOUS AND TAKE SAFETY NEEDED PROCEDURES.]
The Task: In our First Application on ARDUINO we will write a code to Light ON then OFF an LED or say Two Led’s each will go On and Off for several time to show a Blinking light.
What We Need: We will try to be simple on our first project, we will put the Led’s on a braedboard connected to ARDUINO Nano (Any other Arduino Chip can be use). So, we will use Arduino-Board, BreadBoard, Two resistors and tow Led light (I will use One Red, and One Green).
Set-up: We will connect the Red-Led on Pin A3, and the Green-Led on Pin D12, the ARDUINO-Board will take power from it’s USB cable connected to the Laptop.
Coding: The Application will make the Led’s to BLINK in some sequence.
# CODE: Function to turn led On, wait for some delay-time and Turn it off. Two Led's (Red, Green) Blinking const int red_led = A3 ; // set pin A3 for red-led. const int green_led = D12 ; // set pin D12 for green-led. void setup() { pinMode(red_led, OUTPUT); pinMode(green_led, OUTPUT); } void led_on_off (int led, int dt) // Function to Turn led On Wait for delay = dt then turn it off. { digitalWrite(led, HIGH); delay(dt) ; digitalWrite(led, LOW); delay(dt) ; } void loop () { // in both for-loops, change the delay and/or numbers to have different lighting sequences. for (int R = 0; R < 3; R ++) //loop for Red-Led { led_on_off(red_led, 300); for (int G = 0; G < 2; G ++ ) //loop for Green-Led { led_on_off(green_led,110) ; } } exit(0) ; // To stop the action after executing One-Time. }

I am not sure if i will continue in this way or say “New Learning Curve”, The Coding and Commanding an Electronic-Bord to Work as my Application says .. THIS PART WAS WHAT LIT THE FUSE IN MY BRAIN.
