Part 3 of : Control the outputs of ESP-12F IOT module from an Android APP
Upload the following program to ESP-12F IOT module. Before starting this, read my previous blog on the basics of programming ESP-12F IOT module.
#include <ESP8266WiFi.h#include <WiFiClient.h#ifndef APSSID
#define APSSID “PaulESP”
#define APPSK “paulsin91@”
#endif
// Variable to store the HTTP request
String header;
/* Set these to your desired credentials. */
const char *ssid = APSSID;
const char *password = APPSK;
int ledPin = 13; // GPIO13
WiFiServer server(80);
Part 2 of : 32-bit shift register module using ESP-12F IOT module
Important : In the ESP-12F IOT module, jumper should be placed across 5V and COM as encircled in the following image. Otherwise, high voltage may destroy your 32-bit shift register module.
In the previous blog, we saw the circuit for programming ESP-12F IOT module.
