Home Automation with TV Remote
This is 12th project for the course of robotics and iot.
This is to understand the working of transmeter and receiver.TV remote at home operates at 38 Khz frequency, to receive these signals we have to use receiver of the same frequency.
We use TSOP 1738 for having operating frequency of same of 38 Khz. But this is just an information, for driving car you don’t worry about petrol , where it comes from …
Now every switch has decimal address, this address we have to note down by using the library of <”IRRemote.h”> in arduino ide.
Now this address we will copy in our program. We have to use “if” command to compare. If the pressed number is same as shown in the program, that means switch is on and with the programming, we make the arduino pin status HIGH the one connected to relay module of particular appliance.
In this way we can on/off any device.
