Wire_I2C_Connections

Introduccion

In this project we see the connections between our master dispositive ESP32-S3 and our slave devices. The wire connection have at his disposition as 255 devices and with a proper code, we can find and see if one or a few of them are connected.

Materials

We need materials to made our project with hardward components and write our code with an API software.

• HARDWARE

  • Esp32_s3 microprocessor
  • 4 cables to connect the SDA, SCL, CMD and 5V current
  • Slave device: LCD display, sensor of temperature, humidity
  • USB connection calbe C type

• SOFTWARE

  • Visual studio Core
  • Platformio
  • Git
  • Github (Repositions)
  • Libraries (Arduino.h, Wire.h)

Pictures

This code you can see the begining of our desire code

Code

in this point, we'll check a certain code to understand the enviroment we are playing

include <Arduino.h>

#define d 500
#define pin1 21

setup void(NULL){
    Serial.begin(115200);
    pin.MODE(pin1,PULLUP);
}
loop void(){
    Serial.Write(pin1,HIGH);
    delay(500);
    Serial.Write(pin1,LOW);
    delay(500);
}
