Hello all!
I proudly present my Arduino calculator project called ARC (Arduino RPN Calculator).

Hi,
Good to see some success, but you need to post this in Exhibit and Gallery section of the Forum..

Hi,
I watched you YouTube, I have no idea what you are doing, you need to talk us through what keys you are pressing.
You need to do a simple 3 + 2 calculation..

Sorry but the fine text on the screen that I resume shows keyboard navigation is not clear.
Good project mate, just constructive criticism , need some video production.

Hi,
sorry for being not "customer oriented" enough - but producing a video is such a pain (for me).
But have a look at the comment below the video where I described the calculations I made - ie I start calculating 22/7 (PI approximation). That for I type 2, 2, ENTER (green key), 7 and the operation / (yellow function key f and key 9).
To get a clue how I managed the key assignment (I only have 4x3=12 keys) see the end of the readme at github (ie / equals function key f and key 9). There is an onscreen help (bad quality on the video) that shows which keys to press.

What happens if you try to divide by zero?
Nice!
Hello odometer!
Every function which leads to infinite values show +INF or -INF.
Wrong arguments (i.e. ASIN(2)) will print NAN.
This messages are not managed by my code but from the used function that prints a variable.
