Description
The purpose of this assignment was to create a simple circuit using arduino borad to contrl an LED and make it blink. One end of the LED was attahed to ground and the other end to pin 13 of Adruino uno. There was a resistor between pin 13(source) and the LED. The blinking of the LED was controlled using a program written on Adruino .
Components used:
220 ohm resistor (red red brown gold)
1 green LED
Bread board
1 Arduino Uno
Connecting wires
Code:
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(5000); // wait for 5 seconds
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(5000); // wait for 5 seconds
}
