INTRODUCTION

This week for me is obsessive week. I have always liked to send and receive data through UART, and today I will try a new method.

Assignment Description

    group assignment:

  • send a message between two projects

    • individual assignment:

  • design, build, and connect wired or wireless node(s) with network or bus addresses

Components


  • 2 Arduino UNO
  • 1 NodeMcu
  • Rf Module
  • 2 breadboards

    • The Idea and Connections


    I decided to create a network of three phases:

    between NodeMcu and Arduino

    • 3.3v & GND from Arduino to vin & GND on NodeMcu
    • 2,3 from Arduino to D2,D3 on NodeMcu
    • You can get a quick start to Nodemcu from here

    between Rf_Tx or Rf_Rx to Arduino

    • VCC & GND to VCC & GND
    • Data to pin12

    • You can learn more about RF from here


    Steps and Code


    • From browser to NodeMcu
    • From NodeMcu to Arduino
    • From Arduino 1 to Arduino 2 through RF Module
    • Before any thing, you need to burn all codes
    • NodeMcu code, and make sure you set your WiFi Name and passowrd
    • Tx_code on Arduino 1
    • Rx_Code on Arduino 2
    • First, we need to git the IP address from NodeMcu
    • Then, type this IP on your browser and / write the data value..like: 192.168.3.6/Ahmed or 123
    • from Arduino 1 you should see on the mentor the same data
    • Also for the Arduino 2
