I wanted to get recommendations for infrared hardwares. I can think about software setup later.Joel_Mckay wrote: ↑Tue Apr 30, 2019 7:38 amsudo apt-get install lirc
Then search for a tutorial about setting up the interface:

This program has been around for a long time.

I don't like making a mess with jumper cables and a breadboard or prototyping on a breadboard.Joel_Mckay wrote: ↑Tue Apr 30, 2019 11:51 amThey mention a 38KHz amplifier+de-modulator that runs at 3.3v just fine:
Keep in mind there are many different remotes, IR wavelengths, and any one of 34/38/40/56 kHz modulations.
There were a few receivers that could auto-select several frequencies, but I can't recall a 3.3v version at this time.
Some end up using an mcu and a IR-pass filtered-photo-transistor to decode the raw input signal. Dumping a raw signal without decoding the modulation can be more "universal", but such methods are almost always more difficult to handle correctly.
That's a reasonably priced product.PhatFil wrote: ↑Fri May 10, 2019 12:13 amFor a product to use out of the box.. i use a broadcom Rm Mini device https://www.amazon.co.uk/Broadlink-Univ ... B01HPWMWCY
with the rm-node red node within node red on a pi-0-w to issue learnt IR commands via mqtt and alexa voice commands.
imho the drawbacks are :
#1 you need to download and install a phone app to learn codes and
#2 as a wifi enabled 'IOT device lord knows what usage data its sending out to the broadcom corporate servers
its 'seen' and repeated every code i have flashed at it.
and once all codes are learnt you can delete the phone app unless you also want to use your phone to control it via its app?
Good luck with infrared hardwares. But, I gave up on it. You will have to get some help from others.
