Servo Functions

Servo Fuction

The Servo library has a few main functions, but students usually need only attach() and write() for most projects.

Here are the important ones:

Function	Purpose	Example
`attach(pin)`	Connect servo to a pin	`lid.attach(9);`
`write(angle)`	Move servo to an angle (0–180°)	`lid.write(90);`
`read()`	Read the current angle	`angle = lid.read();`
`detach()`	Disconnect the servo	`lid.detach();`
`attached()`	Check if servo is attached	`lid.attached();`
`writeMicroseconds(us)`	Control servo using pulse width	`lid.writeMicroseconds(1500);`
`attach(pin, min, max)`	Attach with custom pulse limits	`lid.attach(9, 500, 2400);`
