 ### Signals and Interrupts
 
-The Servo Input library uses external interrupts to keep track of servo positions without delaying the rest of your sketch. In order for the library to work, you must connect the servo signal wires to [**interrupt-capable pins**](https://www.arduino.cc/reference/en/language/functions/external-interrupts/attachinterrupt/).

 Some third party boards such as the [Teensy 3.2](https://www.pjrc.com/store/teensy32.html) and the [ESP8266](https://en.wikipedia.org/wiki/ESP8266) support external interrupts on all pins. Be sure to check the documentation for your board before connecting your servos.
