So my goal is to operate my TCL Roku TV with my Raspi.
I'm using these LEDs: AIRSUNNY three Legs 5 pairs Infrared Diode LED IR Emission and Receiver and my setup is pretty much identical to this: Creating A Raspberry Pi Universal Remote With LIRC
If I'm holding the Pi ~3 ft from my TV it works just fine. so obviously my code is ok, my circuit is ok, and I'm sending valid signals (via LIRC, an awesome library BTW). However, if I go off-center or more then say 5 m, I get no results... and due to the layout of my room, it's not practical to keep it dead-center. I'm not on an extreme angle, however. I really need to have it work from about 3-4 meters and 20-30 degrees off-center.
So, a couple questions:
Is this a reasonable application? I know tons of people have build remote controls from Raspis but I've found few details on what kind of range they have achieved.
I'm a software guy, with very little circuitry experience. I'm currently working off the 3.3 V rail. should I change to 5 V? would that make a difference to the output strength?
Same as (2) but regarding resistors. would a different resistor make a big difference?
I thought about it afterwards, there was quite a bit of sunlight coming into the room while i was testing. would that have any impact on the TV's IR sensor?
I'm not sure if I have the real-estate on my breadboard, but if I could hook up more LEDs in parallel, how helpful would that be?
I'm hoping this isn't too many questions; any help/insight would be hugely appreciated.
