Steps to do coding in Arduino IDE
1. Open Arduino IDE.
2. For writing this code, we have to add blynk library.
How to add a library:
- Download the blynk library from the github or you can use https://github.com/blynkkk/blynk-library this link.
- Now,Go to Sketch in the menu bar of Arduino IDE,then to Include library
- Next, select the blynk library you downloaded from the above link and after this your library will be added.
Note: If it is showing error in adding the library,then first extract the folder and then add the library.
Complete Code:
#include
#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include
char auth[] = “YOUR AUTH CODE HERE”;
/* WiFi credentials */
char ssid[] = “YOUR SSID”;
char pass[] = “YOUR PASSWORD”;
/* Motion Detector */
#define ledPin D1
#define pirPin D5 // Input for HC-S501
int pirValue; // Place to store read PIR Value
void setup()
{
Serial.begin(115200);
delay(10);
Blynk.begin(auth, ssid, pass);
pinMode(ledPin, OUTPUT);
pinMode(pirPin, INPUT);
digitalWrite(ledPin, LOW);
}
void loop()
{
getPirValue();
Blynk.run();
}
/***************************************************
* Get PIR data
**************************************************/
void getPirValue(void)
{
pirValue = digitalRead(pirPin);
if (pirValue)
{
Serial.println(“==> Motion detected”);
Blynk.notify(“T==> Motion detected”);
}
digitalWrite(ledPin, pirValue);
}
