Arduino – Röle Devresi

Merhaba, arduino devre elemanlarını tanımaya ve onların bağlantı şekillerini öğrenmeye devam ediyoruz.


Görselde gösterildiği gibi bir devre kuracak olursanız devrenin tamamlanmış olduğunu göreceksiniz.


Test Kodu –>

// Include Libraries
#include "Arduino.h"
#include "Relay.h"

// Pin Definitions

// Global variables and defines

// object initialization

// define vars for testing menu
const int timeout = 10000; //define timeout of 10 sec
char menuOption = 0;
long time0;

// Setup the essentials for your circuit to work. It runs first every time your circuit is powered with electricity.
void setup() 
 // Setup Serial which is useful for debugging
 // Use the Serial Monitor to view printed messages
 while (!Serial) ; // wait for serial port to connect. Needed for native USB
 menuOption = menu();

// Main logic of your circuit. It defines the interaction between the components you selected. After setup, it runs over and over again, in an eternal loop.
void loop() 
 if(menuOption == '1') {
 // Relay Module - Test Code
 // The relay will turn on and off for 500ms (0.5 sec)
 relayModule.on(); // 1. turns on
 delay(500); // 2. waits 500 milliseconds (0.5 sec). Change the value in the brackets (500) for a longer or shorter delay in milliseconds.; // 3. turns off.
 delay(500); // 4. waits 500 milliseconds (0.5 sec). Change the value in the brackets (500) for a longer or shorter delay in milliseconds.
 if (millis() - time0 > timeout)
 menuOption = menu();

// Menu function for selecting the components to be tested
// Follow serial monitor for instrcutions
char menu()

Serial.println(F("\nWhich component would you like to test?"));
 Serial.println(F("(1) Relay Module"));
 Serial.println(F("(menu) send anything else or press on board reset button\n"));
 while (!Serial.available());

// Read data from serial monitor if received
 while (Serial.available()) 
 char c =;
 if (isAlphaNumeric(c)) 
 if(c == '1') 
 Serial.println(F("Now Testing Relay Module"));
 Serial.println(F("illegal input!"));
 return 0;
