good morning or afternoon or night
is to see if they could help me with a code; which is a display 4 digits 7 segments with 4 buttons and on the display must show the amount of keystrokes per button. that is to say in each digit a button ..
Yes, can be done.
Do you actually have a display? In which case, give us the web-link which describes it, and tell us what Arduino you want to use.
If you do not, I can advise what one to get, and which Arduino.
OK, well that one is a decent Arduino UNO "clone" or faithful copy of the original, and I gather a reputable company.
The display is quite straightforward. I realise there are various tutorials - I can not find one on the Arduino site proper - describing multiplexing this display directly from the Arduino but I really feel this is a complete waste of time for a poor result.
Perhaps you should explain by the way, what projects and exercises you have done so far with the Arduino before we get too involved with the present project?
In any case, I advise you to get a display with a proper driver; if fact these are best purchased as an integrated module such as this:
Link to store
or with less flexibility in use,
I rather prefer the first - you have eight rather than four digits, but I am sure you can manage.
These have libraries or examples to work with them which makes it very easy.
How about this tutorial to get you started, which I found by following a link from this sparkfun page.
You could also look through the LEDs and Multiplexing section of the forum to look for ideas.
