Using an HC-12 bluetooth in order to turn on and off an LED

Using Arduino General Electronics
1

I am using an HC-12 Bluetooth to communicate between two Arduinos in order to to push a button on one Arduino in order to turn on an LED on another Arduino. The problem is the light is not turning on and I am not receiving messages between my serial monitors. I am pretty sure my wiring is correct, so I think it is my code. I have attached pictures of my circuit just in case.

Sender Code:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); //RX, TX

int buttonPin = 8;

void setup() {
  pinMode(buttonPin, INPUT);
  mySerial.begin(9600);
}

void loop() {
 
  int buttonState = digitalRead(buttonPin);
  
  if(buttonState == 1){//if button is down
    mySerial.println(1234);//send unique code to the receiver in this case 1234
  }
  delay(20);//delay little for better serial communication
}

Receiver Code:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); //RX, TX

int buttonPin = 8;

void setup() {
  pinMode(buttonPin, INPUT);
  mySerial.begin(9600);
}

void loop() {
 
  int buttonState = digitalRead(buttonPin);
  
  if(buttonState == 1){//if button is down
    mySerial.println(1234);//send unique code to the receiver in this case 1234
  }
  delay(20);//delay little for better serial communication
}

The "Receiver" sketch is the same as the "Sender" sketch.
Are they really the same - or did you post the "Sender" sketch twice?
The "Receiver" sketch should enable the means to. . . receive (if mySerial available, Serial.read, and all that).

Instead of sending a number, perhaps try a char (maybe "A" ?)

I figured it out thanks
