Placa releu SPDT 5VDC
Placa 1 releu Placa este compatibila cu Arduino,Raspberry PI si BeagleBone Arduino Cod Sursa (cel mai simplu) int relayOne 2; int relayTwo 3; void setup() { Serial.begin(9600); pinMode(relayOne, OUTPUT); pinMode(relayTwo, OUTPUT); } void loop() { setRelayState(0,1); delay(1000); setRelayState(1, 1); delay(1000); setRelayState(1, 0); delay(1000); setRelayState(0, 0); delay(1000); } void setRelayState(int relay, int state) { if (relay 1) digitalWrite(relayTwo, state); if (relay 0) digitalWrite(relayOne, state); } Cod Sursa (din tutorial) int relayOne 2; int relayTwo 3; String inputString ; boolean stringComplete false; int led 0; int whichRelay 0; void setup() { Serial.begin(9600); inputString.reserve(200); pinMode(relayOne, OUTPUT); pinMode(relayTwo, OUTPUT); } void loop() { if (stringComplete) { if (inputString relay 1 onn ) { setRelayState(0,1); Serial.println( RELAY 1 ON ); } else if (inputString relay 1 offn ) { setRelayState(0,0); Serial.println( RELAY 1 OFF ); } else if (inputString relay 2 onn ) { setRelayState(1,1); Serial.println( RELAY 2 ON ); } else if (inputString relay 2 offn ) { setRelayState(1,0); Serial.println( RELAY 2 OFF ); } else if (inputString relays onn ) { setRelayState(0,1); setRelayState(1,1); Serial.println( ALL RELAYS ON ); } else if (inputString relays offn ) { setRelayState(0,0); setRelayState(1,0); Serial.println( ALL RELAYS OFF ); } else { Serial.print( Unknown command: ); Serial.println(inputString); } inputString ; stringComplete false; } } void serialEvent() { while (Serial.available()) { char inChar (char)Serial.read(); inputString + inChar; if (inChar 39;n 39;) { stringComplete true; } } } Exemple de situatii: setRelayState(0,1) - releu 1 cuplat; setRelayState(1,1) - releu 2 cuplat; setRelayState(0,0) - releu 1 decuplat; setRelayState(1,0) - releu 2 decuplat; void setRelayState(int relay, int state) { if (relay 1) digitalWrite(relayTwo, state); if (relay 0) digitalWrite(relayOne, state); } Un alt exemplu de proiect (tutorial video, aprindere lumina la bataie din palme). Foloseste in plus un microfon . Raspberry PI Actionarea bobinelor releelor se face prin tranzistoare (incluse pe placa), care se conecteaza la pinul 5V Raspberry PI, ceea ce inseamna ca placa nu solicita aproape deloc pinii GPIO Raspberry PI din punct de vedere al curentului consumat de aceasta (curentul necesar este tras din pinul de 5V, iar pinii GPIO dau doar comanda). Vezi filmul de mai jos pentru detalii de conectare.
