Jak wyświetlić V zamiast stopni w woltomierzu?
"Do V jest kanał „licznik energii” - tak podpowiedział mi pzygmunt.
Nie bardzo wiem jak to zrobić. To szczegół, ale byłoby pięknie - woltomierz i V.
program:
Code: Select all
//Wemos D1 mini
//A0 - pomiar napięcia (max 3,2 V)
//Dzielnik 90k+10k(potencjometr)/10k (max 30 V)
