One Channel Infra Red Remote Controller

One Channel Infra Red Remote Controller


One Channel Infra-Red Remote and receiver with onboard Relay provides normally open and normally closed output. The project based on PIC12F683 Microcontroller from Microchip , TSOP1738 used as Infra-Red receiver. Micro-controller decodes the RC5 serial data coming from TSOP1738 and provides high output if the data is valid. The output can be set Momentary or Latch using on board Jumper (J1) and closure. The board provided with 3 LEDs, Power LED, Valid Transmission LED and Output LED. This Remote works with switch No1 of RC5 Remote.


  • Power Supply Remote 2X AA Batteries
  • Power Supply Receiver 7-12V DC
  • Current Consumption Receiver 30mA
  • Onboard jumper for momentary and latch operation selection
  • Transmitter range 10-15 feet
  • RC5 (Philips) Remote
  • Onboard power LED
  • Onboard output ON/OFF LED
  • Onboard Valid Transmission LED
  • Onboard 5V regulator
  • PCB Dimensions 59.06 MM X 29.53 MM

    My name is Matevz and i am student. I have just made a PCB circuit of this project and it doesn’t work. First I double checked the wiring and everything is good. Then I started to measure the pin GPIO2 on which the BC547 is connected and the PIC doesn’t give state “1” 5V. LED that presents receive state of IR sensor is working. Is there any possibility that I get the source code of this project?

    Best regards,

      Hi Matevz,

      Unfortunately source code isn’t available for this project. I would suggest to verify that PIC is successfully programmed and running.

    Is there anyway you could tell me the hex code of the button that is supposedly button no.1 That would help alot

      Could you explain your question?

        şo apparently this circuit should work when i press the button number 1 on any philips remote. I would like to get the IR hex (example:0xFF434) of the button.

          I would suggest you to take a closer look on the RC5 Philips Protocol to check the code for button 1. I think it’s 0x3801, but i am not sure.

    Also I couldnt get TSOP1738 and got another 38kHz sensor. It shouldnt matter as long as it’s a 38kHz one right?

      Yes, it should work. What is the part number?
