Can I use android phone with IR to control light stripe

I have a LED stripe with a classic IR controller (image) and asked myself if I could control it with my Samsung Galaxy s21 Ultra which can emit infra-red light for its ToF camera. Now there are two issues.

  1. Does Samsung provide an API access to control this IR emitter? (The remote control apps I downloaded all say that the phone doesn't have the necessary hardware (IR) for this)?
  2. Is it physically possible, would the IR beam be even strong enough to control the LED stripe driver?
Solution

  • This is unlikely. The ToF IR pulse has to be very specific in length and shape, and likely controlled at the very low level (possibly by the sensor hardware itself).

    So it's not likely that there's a way to customize the pulse shape or duration.
