Relay
Embedded Files
Relay sebagai saklar untuk mengotrol beban yang besar seperti pompa air, lampu, dll
NO (Normaly Open) --> arus terputus saat relay off
NC (Normaly Close) --> arus tersambung saat relay off
note: prinsip penggunaan Relay, sama dengan penggunaan LED
Rangkaian
in (Relay) --> 8 (Arduino)
GND (Relay) --> GND (Arduino)
VCC (Relay) --> 5v (Arduino)
NO (Relay) --> Pompa Air
COM (Relay) --> PLN
Arduino Relay
void setup() {
pinMode(8, OUTPUT);
}
void loop() {
digitalWrite(8,1);
delay(1000);
digitalWrite(8,0);
delay(1000);
}
Rangkaian
in (Relay) --> 22 (ESP32)
