I received the components to build the Arduino Nano IR board, before assembly of the components on the board I decided to first flashed the firmware as detailed in the guide ([Link: harctoolbox.org]). At first I had a problem getting the firmware to flash, until Barf advised me to try changing the baud to 115200 which work a treat.

I am now undergoing a learning curve for IrScrutinizer. I tried exercise 1 & 2 in the help file and all was working okay.

I can learn/teach an IR command from my Panasonic remote (i.e. power toggle) and analyse it ok. But when I press transmit the LED's on the board flash but the TV will not power on or off. I believe the SFH4544 & SFH4546 IR sending LED's are connected correctly (as I see a small infrared receive LED flicker on my old Media Center PC receiver when I press transmit in IrScrutinizer).

I have tried the same thing with different remotes on different devices but I'm having no success. I'm sure I'm missing something obvious.

Any ideas?



Many thanks
