I am writing a code for bridge communication

Need Help With My Project
84

i does it writes the values from transmitter on the pins mentioned below

85

Don’t write bridge in the receiver code

but

BLYNK_WRITE(V1) {
  A36= param.asInt();
}

All that this does…

is to take the value sent on pin V1 and assign it to a local variable called pindata1

Because pindata1 is local, it’s not visible outside the BLYNK_WRITE(V1), and you don’t have any code - either inside or outside of the BLYNK_WRITE(V1) function - to do anything with that variable.

So, it doesn’t do anything.

so how do I fix this sir?

88

Presumably by taking the incoming pindata1, re-mapping it, and writing the re-mapped value to your servo.

I think that personally, I’d do the re-mapping before it’s sent from the transmitting device.

I’d also get rid of these silly aa bb cc dd.... local variables in your void setup - they don’t achieve anything either.

sir can I write the values of pindata1to my object here

91

When you say “your object” do you mean your servo?

If so then yes.

Pete.

92

@PeteKnight yes sir

#define BLYNK_PRINT Serial


#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
#include <Servo.h>


Servo servo1;
Servo servo2;
Servo servo3;
Servo servo4;


// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "ljF4YLcyFN9P6iVeze92GsffvGwSeb2J";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "nitinpa";
char pass[] = "nitinpa1";


    BLYNK_WRITE(V1){
    int pindata1 = param.asInt();
    servo1.write(pindata1);
    }
    BLYNK_WRITE(V2){
    int pindata2 = param.asInt();
    servo2.write(pindata2);
    }
    BLYNK_WRITE(V3){
    int pindata3 = param.asInt();
    servo3.write(pindata3);
    }
    BLYNK_WRITE(V4){
    int pindata4 = param.asInt();
    servo4.write(pindata4);
    }
    BLYNK_WRITE(V5){
    int pindata5 = param.asInt();
    }
    BLYNK_WRITE(V6){
    int pindata6 = param.asInt();
    }

void setup(){
    
    servo1.attach(27);
    servo2.attach(26);
    servo3.attach(25);
    servo4.attach(33);

  

}

void loop()
{
  Blynk.run();
}

will this receiver code work sir :innocent:

So you don’t need to re-map the incoming data values?

i wrote the new transmitter code i mapped the values there :grinning_face_with_smiling_eyes:

#define BLYNK_PRINT Serial
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
#include <Blynk.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "qmppE8kZmNhF8zTuaQdi__QnmIL-Dw1u";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "nitinpa";
char pass[] = "nitinpa1";
char BridgeAuth2[] = "ljF4YLcyFN9P6iVeze92GsffvGwSeb2J";

BlynkTimer timer;

WidgetBridge bridge1(V1);
WidgetBridge bridge2(V2);

void setup() {
  Blynk.begin(auth, ssid, pass);
  
  while (Blynk.connect() == false) {
  }
timer.setInterval(100L, Reading);
}

void loop()
{
  Blynk.run();
  timer.run();
}

void Reading(){
  int A36 = analogRead(36);
  int A39 = analogRead(39);
  int A34 = analogRead(34);
  int A35 = analogRead(35);
  int A32 = digitalRead(32);
  int A33 = digitalRead(33);
    
  
  int mapped0 = map(A36, 0, 255, 1000, 2000);
  int mapped1 = map(A39, 0, 255, 1000, 2000);
  int mapped2 = map(A34, 0, 255, 1000, 2000);
  int mapped3 = map(A35, 0, 255, 1000, 2000);

  bridge2.virtualWrite(V1, mapped0);
  bridge2.virtualWrite(V2, mapped1);
  bridge2.virtualWrite(V3, mapped2);
  bridge2.virtualWrite(V4, mapped3);
  bridge2.virtualWrite(V5, A32);
  bridge2.virtualWrite(V6, A33);
}

BLYNK_CONNECTED() {
  bridge2.setAuthToken("BridgeAuth2"); // Token of the hardware B
}

will this transmitter code work sir :sweat_smile:
