One Channel infra-red remote controller using arduino

One channel infra remote controller required , 5V one channel relay board, Arduino UNO, TSOP1738 IR sensor, IR remote. Circuit required 5V DC supply, USB power is OK to run the project. The relay board schematic link provided bellow.

Note : Relay board works on 12V, I have used 5V relay instead of 12V so it directly can power up from Arduino.
