🔴 IR receiver

By adding an IR receiver, you can control the device with almost any common remote — such as a TV remote you already own.

Most remotes operate around the 38 kHz frequency band. While many IR sensors and modules will work, a good starting point is the TSOP382 series (e.g. this).

🔧 Configuration

Data

Data-line for received signals.

Any digital input pin can be used.

Configure in secrets.h:

#define PIN_IR 1 // Receiver

[!WARNING] Avoid strapping pins as this pin is pulled HIGH when idle.

🧩 Extension

Using the Infrared extension, the device can be controlled using a remote control.

Check out the Infrared extension for more info.

🚫 IKEA Frekvens

The device was originally designed with an IR sensor in mind, but the feature was never implemented in production. The unused hole next to C10 can, however, be repurposed for adding one.
