δυο project σε ενα arduino mega
0
καλησπερα και παλι.
ποσο εφικτο ειναι σε εναν arduino mega να ''κουμπωσουν'' δυο διαφορετικες κατασκευες?????
το ενα ειναι ενα μπαρομετρο που μετραει την πιεση της τουρμπινας του αυτοκινητου και εχουμε απεικονηση σε μια οθονη lcd 20x4 χαρακτηρων και το αλλο ενας θερμοστατης που εχουμε απεικονηση σε μια οθονη lcd 16x2 χαρακτηρων.ανεβαζω και τους κωδικες

δεν ξερω εαν ειναι δυνατο να γινει κατι τετοιο,το ευκολο για μενα θα ηταν να κανω δυο διαφορετικες κατασκευες αλλα αυτο σημενει δυο arduino και μεγαλυτερο κοστος
