Hi friends, in this instructable I am going to show you how to make remote control led by using the unuseful buttons of your Television remote. In this project, we are not going to use trimpot, resistor or IC. So, let's do it!!!

Step 1: Gather the Parts-

b) Arduino UNO.

c) T.V. remote.

Step 2: Gather the Tools-

Soldering gun.

Soldering stand.

Soldering wick.

Soldering metal.

Step 3: Draw the Schematic

Draw any one of them.

Step 4: Solder the Components-

Step 5: Comparison-

Step 6: Code-

i) First we have to decode the remote's button's code. This can be done by uploading the first code given above.

After uploading the code, open Serial Monitor and press any button of your T.V. remote which is not useful. The code of the button will be displayed and below that FFFFF will be displayed which means that the code is repeated continuously.

ii) Now we have to copy the code of the T.V. remote button which we got, in another code to implement it. This can be done by uploading the second code given below.

Now press the button of the T.V. remote of which we took code. When you will press it, the led will blink.

Thank you :-)
