Blinka

Detta är ett bra nybörjarprojekt med Arduino som får en lampa att blinka.

Till detta projekt behövs:

  1. Arduino
  2. LED
  3. 220 ohm resistor

 

Börja med att vira eller löda ihop ledens långa ben (positiva) med den ena sidan av resistorn. Sedan så ska du ta och koppla i den andra sidan av resistorn i pin 13 på ena långsidan och det korta benet (negativa) i GND dom är bredvid pin 13img_20161227_185046_resized_20161227_065816529

Kod

 

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino model, check
the Technical Specs of your board  at https://www.arduino.cc/en/Main/Products

This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
delay(1000);                       // wait for a second
digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
delay(1000);                       // wait for a second
}

 

Detta kommer att resultera i att lampan kommer att börja blinka.img_20161227_185219_resized_20161227_065942284
