Smart Display With Nokia5110 and ESP8266 | Amazing Mj

video link:- Play

In this project, we gonna control the nokia5110 display with a mobile phone using the HTTP protocol.

link to download application:- Smart Display App

I change the name of the button in the application to image1, image2, and image3
so if you want to take action when image1 button click its send data "image1"
same as image2 and image3


Here the Arduino code and circuit diagram

code :

#include <ESP8266WiFi.h>
#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Adafruit_PCD8544.h>

String I;    // data from the mobile app.
String text;
int x, y;
char z;
                         //Adafruit_PCD8544(CLK,DIN,DC, CE,RST);
Adafruit_PCD8544 display = Adafruit_PCD8544(D1, D2, D3, D6, D5);
