Description:
Our first assignment was to connect a simple circuit and get the LED to blink. The setup was done by connecting my Macbook Pro to an Arduino board. The Macbook sends a signal through a 220 Ohm resistor to a blue LED.
Components Used:
- 1 Arduino UNO
- 1 Blue LED
- 1 Breadboard
- 1 220 Ohm resistor
Code:
I modified the code to create a longer interval for the blinking.
/*
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
}
