Ocigledno ti ne radi prijemnik kako treba. Malo se pozabavi sa njim. Na njegov izlaz mozes cak
spojiti i slusalicu pa da cujes signal (ako ga on uopste prima).

Schematics of a transmitter and a receiver for data communication (suitable for alarms) on 433 MHz.
The big fat lines on schematics are actually PCB traces with specific dimensions as noted.

Napravio sam uvaj uredjaj ali imam jedan problem podatke salje i prima samo ako korisiti isti
izvor struje ako se prijemnik i predajnik nakace na baterije ili na neki drugi izvor energije
prenos podataka je nemoguc. kada pokusam da posaljem bilo sta na predajniku blica led a na
prijemniku stalno svetli.

mislim, svaka cast shemi, ali za nest pouzdano nije vrijedno maltretiranja. 20 eura nije bas
tak strasna lova.

postoji integrirani tx i rx, cijena oko 10eura. sto se tice komunikacije kontrolera, skinite
datasheetove za HT6014 i HT6034 (ili neke alternativne integrirce). to su enkoder i dekoder,
paralelni ulaz serijski izlaz s rolling kodovima (obrnuto kod rx)

TX radi, ali RX ne znam podesiti. LED-ica ponekad zasvjeluca (kad vrtim trimere, a ne zbog
predajnika). TX radi stabilno na frekvenciji 363 i nešto sitno MHz, mogu ga podesiti na oko
450 MHz ali nije tako stabilna frekvencija. Trebalo bi malo smanjiti zav
