Hi all. I'm very inexperienced with Arduino. I've made a small submersible. It has a magnetic switch that turns on a motor for a set length of time. To do this I've used a very simple if statement with a delay to time it.

sketch here  
#include \<Servo.h\>

Servo esc;  
Servo servo;  
void setup()  
{  
esc.attach(3);  
servo.attach(2);

Serial.begin(9600);  
// Since the other end of the reed switch is connected to ground, we need  
// to pull-up the reed switch pin internally.  
pinMode(Reed, INPUT\_PULLUP);  
esc.writeMicroseconds(1000); // send "stop" signal to ESC. Also necessary to arm the ESC.  
delay(5000);  
servo.write(90);  
}

void loop()  
{  
esc.writeMicroseconds(1000); // send "stop" signal to ESC. Also necessary to arm the ESC.  
int proximity = digitalRead(Reed); // Read the state of the switch  
if (proximity == HIGH) // If the pin reads low, the switch is closed.  
{

```
esc.writeMicroseconds(1000); // send "stop" signal to ESC.;       

```

delay(15);  
}  
else  
{  
delay(1000);  
esc.writeMicroseconds(2000); // send "stop" signal to ESC. Also necessary to arm the ESC.; // sets the servo position according to the scaled value  
delay(60000);  
}

}

I've since added a servo connected to a rudder that uses an HMC5883L magnetometer sensor to keep the sub in a straight line.

So my question is, how do I time the esc to turn off after a set amount of time while allowing the programme to routinely check the magnetometer and adjusting the servo accordingly

Take a look at the blink without delay example in the IDE, without delay.
