IR Remote


IR is a very common means of communication. This demo will show you how to use IR send and receive module.
Large of household appliances is controled by IR Remote, such as TV, air conditioning and so on.
We can use IR module to control those appliances also.
Hardware Required:
  • Arduino
  • IR Emitter
  • IR Receiver
  • Button
IR Emitter connect to D3 and IR Receiver connect to A4.
There are two part of code: get value of Remote and Send command.
Get Value of Remote:
Open revTest of IRSendRev Library, open Serial Monitor. Take your Remote, press a button, then you can find a series of number had been printed.
This series of number is what we need, note it, we’ll use if later.
Send Command
Open Arduino IDE, click File->Sketchbook->infrared.
If you had get the value of your TV turn-on-off key, then point infrared emitter to your TV, and press the button.

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:
  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.
An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.
Happy hacking
