In this project we are going to find different codes for different keys of remotes. This is done with the help of Arduino and some components  such as LCD, TSOP 1738 Decoder. each button of remote has different code. By using TSOP and LCD we are going to find this code.

In programming we are using special library used for Decoders and its respective functions. When we press any button of remote some signal are obtained. Such signals are not in readable form. For that we using TSOP 1738 decoder. This will covert those signals into some readable form and with the help of LCD we are going to read those codes.

Components Required:

  • 1 x Arduino Board with USB Cable
  • 1 x Bread Board
  • 1 x LCD
  • 1 x 10 kilo Ohm Potentiometer
  • 1 x 39 Ohm Resistor
  • 1 x TSOP 1738
  • Bread Board Connecting wires

Arduino Schematic:

Assemble the circuit as shown in the above diagram. The program for Arduino is mentioned below. Please check the connections twice before you give power to the circuit. Paste below code in arduino and upload it to the board.
