Start Arduino

Witam wszystkich formowiczów Arduino.
Nie dawno zacząłem przygodę z arduino i zaczynam od podstaw.
Mam pytanie i to mój pierwszy problem.
Jest to projekt do zasilania awaryjnego gdzie w przypadku zaniku napięcia sieci załączany jest ups z akumulatora 120Ah. Chcę by na wyświetlaczu wyświetlane dane typu napięcie prąd moc pobierana oraz czas do rozładowania akumulatora.
Napisałem już część programu i wyświetlają mi się dane. I tu mam problem gdyż za wyświetlanymi danymi pojawiają się nie pożądane dane /dziwne znaki prostokąty itp/.
Proszę o podpowiedź. Pozdrawiam.

This is the English language part of the Forum. I don't know what language you have posted your question in.

Google translated from Polish into my language.

@PiotrMk71:
Please read and follow the forum rules first.
When posting code:

  1. put your code in code tags - and not as an attached picture
  2. let us know about ALL your code and not only a snippet - to help you, we must know the whole contextual information
  • Firstly you should tell us about your display and
  • how you connected it to your Arduino.

Did you run the simpe basic example with "Hello World" on your display and did that work without errors and strange characters? If that fails already, then you should fix that first before you transfer your measurements to that display.

AND: pls use English language in your reply - let Google or another translator assist you if you have problems with the non-native language.

Hi,
OPs google translated.

Hello all Arduino Formers.
I have not been to Arduino for a long time and I'm starting from scratch.
I have a question and this is my first problem.
This is a project for emergency power supply where in the event of power failure, the power is turned on the 120Ah battery.
I want the display to display voltage data, current, power input and time to discharge the battery.
I have already written a part of the program and the data is displayed to me.
And here I have a problem because the displayed data does not show the desired data / strange rectangular characters etc.
Please give me a hint. Regards.
