Prerequisites

Basic knowladge of making electrical circuitary/connections and C/C++ programming language.

Components list

• Arduino UNO
• TSOP1738
• IR TV/DVD Remote or any Generic Remote
• Relays 5 volt module
• Bulb with holder
• Connecting wires
• Bread board
• Power supply

Other Tools Needed:

• Soldering Iron
• Soldering Wire
• Soldering paste
• Non-metallic Box(used as enclosure for the device)
• Utility Knife and glue

Tutorial

Follow these steps for complete connections and circuitary.

Step 1: Solder IR sensor On The PCB.

In this step we need to solder the TSOP1738 IR sensor to a small piece of PCB. Like the image given above.

Step 2: Connect "TSOP1738" with Arduino.

Pin Diagram of TSOP1738

• Arduino +5V -> TSOP1738 Vcc or +5V
• Arduino Gnd -> TSOP1738 Gnd
• Arduino Pin 11 -> TSOP1738 Pin OUT

Arduino Pin 11 will take input from TSOP1738

Step 3: Test "TSOP1738" output with Arduino Serial Monitor

Hex Value Table

Button	Hex Value
0	0x1FEE01F
1	0x1FE50AF
2	0x1FED827
3	0x1FEF807
4	0x1FE30CF
5	0x1FEB04F
6	0x1FE708F
7	0x1FE00FF
8	0x1FEF00F
9	0x1FE9867

Now use these codes in arduino sketch. When these codes match with the stored one do something. You can see these in my code that decodes the IR remote control button and shows the button number on the serial monitor.

Step 4: Connect Relays according to your purpose

Relay Connection

Step 5: Final Circuit
