# Infrared Remote Control

> 38KHz infrared remote with 20 function keys

38KHz infrared remote with 20 function keys. Use together with the [IR Receiver module](/parts/wokwi-ir-receiver).

## Function keys

The keys send infrared messages encoded using the [NEC frame format](https://exploreembedded.com/wiki/NEC_IR_Remote_Control_Interface_with_8051#NEC_Protocol). Each key sends a different command value (see the table below), and the address field is always 0.

Each key has a keyboard shortcut that actives the key while the remote is in focus.

The following table lists the NEC command, NEC encoded value and keyboard shortcut
for each of the keys:
