Greeatings .
I need some help with my project for elevator display.
I have 2 pushbuttons , they are my inputs .
Those 2 buttons will show me number of floor.
For example if the state of input 1 and input 2 are low on my display show floor zero.
if boot input high the foor is 3 .
have some one similary code
thanks a lot
Hi,
A table showing what you want to display with ALL combinations of the 2 inputs.
| Button1 | Button2 | Display |
|---|---|---|
| LOW | LOW | 0 |
| LOW | HIGH | 1 |
| HIGH | LOW | 2 |
| HIGH | HIGH | 3 |
Does it look familiar?
What is your electronics, programming, arduino, hardware experience?
What arduino are you using?
What display are you using?

i using arduino mega , and tft 3.2 sainsmart ITDB32S .
your table is correct for my project i need hel how can i read this input and show on my display .
i can with if else but i have to much case ?
have you better idea ?
I use UTFT library
Hi,
You are counting in binary..
Can you tell us your electronics, programming, Arduino, hardware experience?

Not sure what you mean.
Please post your code.

Hi,
Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Thanks.. Tom..
