I am trying to set up my Arduino as a replacement remote control. The setup works and I can use it to turn on/off my things, for example my fan.
However, the working distance is quite short. Around a meter. The actual remote for my fan works across the distance of my apartment.
What can I do to improve the working distance of my Arduino remote? Does the LED need a back reflector or something? Does it need a different LED?
The LED I am using is this, it came in a bundle I purchased. https://www.amazon.com/dp/B07PJC7WSQ/#detail-bullets
