Pe ecran, informatiile se prezinta asa:
Am facut un film, numit indicator date mediu - masina in care am simulat toate situatiile, care am crezut eu ca pot exista, ca valori:

Deoarece am reusit "performanta" de a strica 2 placi Arduino (partea de interfata USB + microcontroler ATmega328P-PU) din cauza consumului mare pe ramura de 5V, recomand utilizarea unui stabilizator extern pentru 5V...
