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?
