NODEMCU 1.0 (ESP8266) CONTROLLED RELAY USING BLYNK (OVER THE WEB)
HEY GUYS MY NAME IS P.STEVEN LYLE JYOTHI AND THIS MY FIRST INSTRUCTABLE ON HOW TO CONTROLL A RELAY USING AN NODEMCU ESP8266-12E AND BLYNK OVER THE INTERNET
SO LETS GET STARTED
SORRY FOR MY BAD ENGLISH
SO LETS GET STARTED
SORRY FOR MY BAD ENGLISH
THINGS YOU WILL NEED
1. NODEMCU ESP8266-12E (http://www.ebay.in/itm/Genuine-NodeMcu-ESP8266-Boa...)
2. 4CH RELAY(http://www.ebay.in/itm/FOUR-CHANNEL-4-CH-5V-RELAY-...)
3. SOME WIRES

NOW THE APP PART IS DONE
PROGRAMING THE NODEMCU ESP8266-12E
1.FIRST INSTALL THE ARDUINO IDE (http://download.arduino.org/IDE/1.8.1/arduino-1.8....)
OPEN ARDUINO
2.GO TO FILE=>PREFERENCES AND IN THE ADDITIONAL BOARD MANAGER PASTE THIS LINK (http://arduino.esp8266.com/stable/package_esp8266c...)
3.AND NOW GO TO TOOLS=>BOARDS=>BOARD MANAGER
4.NOW IN THE BOARD MANAGER SEARCH "esp8266"
5. NOW IN THE BOARD MANAGER YOU WILL GET "esp8266 by ESP8266 community"
6.INSTALL THE LATEST VERSION IN MY CASE IT WAS 2.3.0
7.NOW INSTALL THE BLYNK LIBRARIES BY GOING TO "Sketch=>Include Libraries=.>Manage Libraries
8. NOW IN THE Library Manager SEARCH FOR "BLYNK"
9.YOU WILL GET "Blynk BY volodmyr shaymka"
10.INSTALL THE LATEST VERSION IN MY CASE IT WAS V0.4.3
11.NOW CONNECT YOUR NODE MCU TO YOUR PC\
12.GO TO TOOLS=>BOARDS=>NODEMCU V1.0(ESP8266-12E)
13.SELECT YOUR COM PORT IN MY CASE IT IS COM5
14.NOW GO TO TOOLS=>PROGRAMMER=>"Arduino ISP"
5. AND UPLOAD THIS CODE (https://github.com/stevenchanti/P.STEVEN-LYLE-JYOT...)TO YOUR NODEMCU (CODE WILL BE IN THE FILES ATTACHMENTS)
===================================================================================
IN THIS CODE YOU HAVE TO CHANGE SOME THINGS LIKE YOU HAVE TO GIVE YOUR WIFI SSID AND PASSWORD WHICH YOU WANT TO CONNECT AND YOU SHOULD GIVE THE AUTH TOKEN THAT YOU GOT IN EMAIL
IF YOU HAVE ANY PROBLEM CONFIGURING THE NODE MCU WITH THE ARDUINO THEN GO AND SEARCH ON GOOGLE
OPEN ARDUINO

6.NOW SOLDER THE D4 OF THE NODEMCU TO THE IN4 OF THE RELAY
2.NOW SOLDER THE VIN OF THE NODEMCU TO THE VCC OF THE RELAY
3.NOW SOLDER THE D1 OF THE NODEMCU TO THE IN1 OF THE RELAY
4.NOW SOLDER THE D2 OF THE NODEMCU TO THE IN2 OF THE RELAY
5.NOW SOLDER THE D3 OF THE NODEMCU TO THE IN3 OF THE RELAY
6.NOW SOLDER THE D4 OF THE NODEMCU TO THE IN4 OF THE RELAY
TEST YOUR PROJECT
1. NOW POWER YOUR NODEMCU
2. NOW OPEN THE BLYNK APP
3. NOW OPEN YOUR PROJECT
4.CLICK ON THE MICROCONTROLLER ICON TO CHECK WHETHER THE DEVICE IS ONLINE OR OFFLINE
IF THE DEVICE IS ONLINE THE DEVICE IS WORKING AND PRESS THE BUTTONS TO CONTROLL THE RELAY
NOW THE PROJECT IS COMPLETE THIS IS MY FIRST INSTRUCTABLE SO SORRY FOR MY BAD ENGLISH
