Such remotes are used to control TVs, air conditioners, projectors, audio systems, and more. The saved signals can be played back to send commands instead of the original remote. On this page, you’ll learn how to read, save, and emulate IR signals with your Flipper Zero. *** # Capturing infrared signals Flipper Zero captures and demodulates IR signals with a carrier frequency of 38 kHz using its [built-in IR receiver](https://docs.flipper.net/zero/infrared#FOaB8). For remotes with known protocols, Flipper Zero automatically decodes IR signals. If the protocol of the remote is unknown, Flipper Zero will record the signal in RAW format. To capture and save a signal, do the following: ::::WorkflowBlock :::WorkflowBlockItem Go to **Main Menu** **-> Infrared -> Learn New Remote**. ::: :::WorkflowBlockItem Position your IR remote in the line of sight of the IR receiver of your Flipper Zero. ::: :::WorkflowBlockItem On your IR remote, press the button you want to be recorded by your Flipper Zero. ![](https://api.archbee.com/api/optimize/3GUDYkC5JgUWgo6RW8piO-LnLkB1XgiOWAampVLoqEE-20241025-105531.png "Keep your remote in the line of sight of the IR receiver") ::: :::WorkflowBlockItem Once the signal is captured, you’ll see the remote protocol name on the screen of your Flipper Zero. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/P5i59VFhO3r7a5faLYyZS_image.png "The captured data is displayed on the screen") ::: :::WorkflowBlockItem To save the captured signal, press **Save**, name the button, and press **Save** again. ::: :::WorkflowBlockItem After saving the first button, Flipper Zero creates a virtual remote with the new button. You can add a new button to the remote by selecting ➕. ::Image[]{src="https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/Z2gqQG_RkhpyfcvtNRXnh_image.png" size="80" width="1400" height="1288" position="center" caption="Add new signals to the virtual remote" showCaption="true"} ::: :::WorkflowBlockItem To customize or delete the virtual remote, select **Edit**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/IpW7hzpRvknmD2ijvy0al_image.png "Customize your virtual remotes") You can also customize saved remotes by going to **Main Menu** **-> Infrared -> Saved Remotes**. ::: :::: :::Iframe{code="
Mind that Flipper Zero can capture IR light from the Sun or a home bulb while trying to capture a signal from a remote.

To send a signal, do the following: ::::WorkflowBlock :::WorkflowBlockItem Go to **Main Menu** **-> Infrared -> Saved Remotes**. ::: :::WorkflowBlockItem Select the saved remote from the list of remotes. ::: :::WorkflowBlockItem Point your Flipper Zero at the device you want to control. Make sure that the IR transmitter of your Flipper Zero is facing the device. ::: :::WorkflowBlockItem To send the command, select the button you want to emulate and press the %ok%**OK** button. ![](https://api.archbee.com/api/optimize/3GUDYkC5JgUWgo6RW8piO-aYbGhFk9yDTFsFuyRVB2A-20241025-105637.png "To send a signal, point your Flipper Zero at the device and press the %ok%OK button") ::: ::::
