With this project, you can control the home appliances / relays/ leds with simple touch operation, it will be quite useful when normal switches gives sparks , in a highly flame able zones, and cause the accidents, don't feel bad, if you are already know this technology,please go through the next steps to make the automation system.

Step 1: HARDWARE YOU NEED

1. Arduino UNO

2.2.4 Inch TFT LCD Dsiplay

3.some hook up wires / connecting wires

4.led/ relay board

the above hardware can be available from any online store, you want...

connect the led's to pin 13,12 or if you are using relay board connect relay 1, relay 2 to pin 13, pin 12 respectively.

Step 2: Source Code

for library and source code please click on the below link:

http://prasadtronics.blogspot.in/2017/06/arduino-t...

or if you have the patience please copy the code and add necessary library to your arduino:

sorry i don't have the video, but i will upload the video soon......

find the libraries here:

Step 3: Final Output

The final output of the project will be as shown in the picture, you can add number of devices but, don't forget to use mega2560 boards, as it does have more i/o pins.
