hello ,
I am creating a motion detector with a PIR module connected to an ESP8266. And I would like my lamp also controller with an ESP8266 to be activated when a movement is detected. Only when a movement is detected nothing happens on the second device yet the movement is detected on the first device
here is the motion sensor code:
You’ll need:
- Blynk IoT app (download from App Store or Google Play)
- ESP8266 board
- Decide how to connect to Blynk
(USB, Ethernet, Wi-Fi, Bluetooth, ...)
There is a bunch of great example sketches included to show you how to get
started. Think of them as LEGO bricks and combine them as you wish.
For example, take the Ethernet Shield sketch and combine it with the
Servo example, or choose a USB sketch and add a code from SendData
example.

// Template ID, Device Name and Auth Token are provided by the Blynk.Cloud
// See the Device Info tab, or Template settings
#define BLYNK_TEMPLATE_ID "--"
#define BLYNK_DEVICE_NAME "--"
#define BLYNK_AUTH_TOKEN "Auth Token A"
const int pirPin = D0;
bool pirStatus = false;
int timerr = 0;
// Comment this out to disable prints and save space
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = BLYNK_AUTH_TOKEN;
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "---";
char pass[] = "---";
WidgetBridge bridge1(V0);
BlynkTimer timer;
void setup()
{
// Debug console
Serial.begin(115200);
pinMode(pirPin, INPUT);
Blynk.begin(auth, ssid, pass);
timer.setInterval(1000L, myTimer);
bridge1.setAuthToken("Auth Token B");
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
}
void loop()
{
Blynk.run();
// You can inject your own code or combine it with other sketches.
// Check other examples on how to communicate with Blynk. Remember
// to avoid delay() function!
timer.run();
Blynk.virtualWrite(V2, pirStatus);
Blynk.virtualWrite(V5, timerr);
pirStatus = digitalRead(pirPin);
}
void myTimer()
{
timerr = timerr+1;
if(pirStatus == 0 && timerr >= 20){
bridge1.virtualWrite(V24, 1);
Blynk.virtualWrite(V1, 1);
}
else
{
bridge1.virtualWrite(V24, 0);
Blynk.virtualWrite(V1, 0);
}
if(pirStatus == 1){timerr = 0;}
}
and here is the lamp sensor code :

*************************************************************
This example runs directly on ESP8266 chip.
Note: This requires ESP8266 support package:
https://github.com/esp8266/Arduino
Please be sure to select the right ESP8266 module
in the Tools -> Board menu!
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!

I modified the code so that it sends the information by serial port and not that it turns on the light
Thanks to anyone who takes the time to respond.
