Today i will Let you know , How to make an Mini Esp 12 Wifi Relay Board measuring only 3.9cm x 3.9 cm!
This Board has some very Cool Features which every Tech Lover will Love to Have.
I have Included all files in next Steps.
This Boards Packs with
- WPA2 Encryption
- A Flat Design User Interface ( Shown in Picture Above )
- Fast Control
- Temperature ( Code for Temperature Support will be coming in few weeks.)
- USB Powered
- Update the Board from Computer with one Click ( Updated Firmware will be Provided by me on bubblesaqua.com)
- This Board features an Amazing feature too, It will remember you last switch State! This means if there is an Power Cut then this Board will come back to it's Previous State which was before power cut.
- This Board also Includes an Picture or Video Guide on Board.
These many Features for $14 is amazing + you get an range of 10-20Meters ( Indoor , 18 < fair - poor connection) and Out door will be even More! This Module is still in Final Software Prototypes , Just like last version but in here i have posted an Stable code for all of you. leaving the temperature sensing feature, All other Features are Included.
Step 1: Interface ScreenShots
I have Taken these Screen Shot for your Personal Point of View , You will surely like the way i designed the Webpages according to trending Flat Design Websites! :) Tutorial Starts from next Step.
Step 2: Get Materials
You can Buy a Kit from my Official Website : bubblesaqua.com
or you may Source your Parts Yourself.
Anyways List is Here:
1x Relay (5v)
1x BC814 (sot-23)
1x M7 SMD Diode
1x Micro USB Connector
1x 0805 SMD Green LED
5x 12Kohm 0805 Resistors
2x 0805 0.1uf Capactor
1x AMS1117 Regulator
1x 4.7KOhm 0805 Resistor
2x 150Ohm 0805 Resistor
Step 3: Arduino Code
First of all Download All the Files Necessary.
I made this in Arduino IDE 1.6.7 : Link to Download : Click Here
Now Download ESP8266 Arduino Library + Boards : Click Here
Go There & Follow Instructions there on how to install this library + boards.
After this, Download this File System Tool for ESP8266 by which you would be able to upload html and other files to ESP8266 File System - Click Here
Now Get My Code + PCB at Github - Click Here

Step 4: Now Soldering! : Start by Micro USB
Solder Micro-USB on PCB.
Step 5: Solder: ESP12F
I Had ESP-12F . So, I soldered this.
After this I Programmed ESP-12f By Soldering Jumper wires to Required programming pins and Programmed it through my Cp2102 Module.
You can Find many info on Internet on How to Program ESP12. Ask your Google Uncle! :D
Step 6: Solder: BC814
Solder BC814 SMD Transistor.
Step 7: Solder: M7 Diode
Now, Solder M7 Diode as Shown in Pic. Make sure of the Mark. Lines Like this '||' on diode should be hole facing.
Step 8: Leave These Points
These Points were Intended for Status LED but didn't worked like i wanted. so, leave these points Un-Soldered.
Step 9: Solder: 12KOhm Resistors
Solder 12KOhm Resistors at R1, R2, R3 ,R4, R8
Step 10: Solder: 0.1uf SMD Capacitor
Solder Capacitors at C1, C2
Step 11: Solder: 150Ohm Resistors
Solder 150Ohm Resistors at R6, R9
Step 12: Solder: 0805 Green LED
Solder Green LED at 'Power'
Step 13: Solder: Regulator 1117
Solder Regulator at 'REG'
See photo for my Personal Comment.
Step 14: Solder: 5v Relay
Now , Solder 5v Relay
Step 15: Solder: 3 Pin Screw Terminal
Solder: 3 Pin Screw Terminal for ReUsage , Whenever you want to detach wire, unscrew it ;)
Step 16: Done!
Done! , Now Enjoy your Wi-Fi Module and Help Yourself with Laziness ;)
Don't Forget to Support me and Vote me in 101 Digital Contest :)
Step 17: Now, How to Start Playing With It?
1) Power this Up
2) Connect it's Wifi Hotspot to your Phone /PC / Laptop. ( ID : Bubbles Aqua )(Password: fishes123)
3) Open any Browser
4) Open "192.168.4.1" in URL Section
5) A Cool webpage will be opened where you will get many Options
6) Click on Switch Tab
7) A New Webpage will open where you can control your board with a tap/click!
( It will Also Show it's Current State ie. ON or OFF )
