//Programming:
int relay1 = 8;
int relay2 = 9;
int relay3 = 10;
int relay4 = 11;
char val;
void setup() {
Serial.begin(115200);
Serial.begin(9600);
pinMode(relay1, OUTPUT);

pinMode(relay3, OUTPUT);
pinMode(relay4, OUTPUT);
}
void loop() {
while (Serial.available() > 0) {
val = Serial.read();
Serial.println(val);
}
//Relay is on
if ( val == '1' ) {
digitalWrite(relay1, HIGH);
}
else if ( val == '2' ) {

}
//relay all on
