"Project 1"->CA IR-Remote-> Migration Mega2560 to Arduino Uno

[admin]

so, 
got today my Arduino "Geekcreit® UNO R3 ATmega328P" for only 3€ from

Bangood->"https://www.banggood.com/UNO-R3-ATmega32...64163.html"
(i order there somtimes, because of faster shipping times->is between 7-24 days, and it arrives (2 times now) before 3 weeks)


the "migration" from the Mega2560 to the Uno works "perfectly" (hooray !!) 

but there are some things to notice:

1. connected under Win8.1 i got first an "unknown" usb-device; knew it, but thought it will work anyway..
    had the driver (there also on the site) and u got it a million times in the web, but here again anyway..
    .exe,install,works..
    
  ch341ser.zip (Size: 178.97 KB / Downloads: 0)
2. the "irsend"-pin is on the Uno on "PIN 3" not on Pin9 as the Mega2560...


so, by that i´ve modified the sketch/.ino over the last weeks, and now we have an "initial"-sequence   (which is unneccessary for the function but funny)




and here the modified sketch (works without changes (only pin3 for pin9)) on the Mega2560 and Uno->

  bluetooth-w1-works-list-avmd-ba3-lcdprint3-fi9.rar (Size: 1.39 KB / Downloads: 0)

and here in "clear": (and now with a "Backlight off !!"-function ; means u can set the display "off"/dark).
