IR Remotes

Several years ago, I upgraded our entertainment center, and added a Logitech Harmon one remote.   The Harmony was great, it cotrolled everything we had on the entertainment center, without a hitch.   While doing the upgrade, I ran into the HDCP problem with our TV, it only had one HDCP compliant input.   So I bought an HDMI switch that honored the HDCP protocol.   HDMI switches usually have an auto mode which will switch to an HDMI input that is on, however, ROKU and some other devics don't turn their HDMI output off when you're not using it.   When I installed the switch, it worked great at switching HDCP signals but it wouldn't respond to it's own IR remote.   We don't switch back and forth a lot so It wasn't a killer.  

Some time later we started streaming our TV and since out UHD TV was just old engough it didn't stream, I bought a Roku Streaming Stick+.   Recently I decided to try to get the Logitech Harmony one to control our Roku, but, alas, the Harmony only spoke IR and the Roku only spoke RF.   In the process, I decided to get a better HDMI switch.   I bought a Kinivq PRO 550BN HDMI switch from Amazon, which would let me turn the auto feature off, but neither it's own remote or the Harmony would control it.  

I put together an IR reader using an Arduino and IR sensor to check the remote.
