Prin toamna am facut un termometru cu 2 senzori LM335 si afisajul LCD 16x2, pe care l-am prezentat in 2 articole:
- Termometru dublu cu LM335Z si un afisaj LCD cu 16 coloane si 2 randuri
- Termometru dublu cu LM335Z si un afisaj LCD cu 16 coloane si 2 randuri (II)
si foloseam schema de conectare, care include si un LED multicolor pe post de indicator de confort:
Pentru inceput a trebuit sa iau la mana sketch-ul anterior si sa-l inteleg si, eventual, sa modific ce nu-mi place si ce am eu nevoie. Am creat si un caracter pentru unitatea de masura (grad Celsius) si am facut o numaratoare a temperaturilor de la +99 la -99 grade Celsius, pentru a aranja si cifrele, cand sunt cu o singura cifra, sau cu 2 sau e zero fara semn.
Rezultatul se vede in 2 filmulete, primul in romana si al doilea cu ceva engleza (am facut asta pentru a multumi si partea romana si cea externa, sa zic asa):
- testare afisare caractere mari pe LCD16x2
