  1. Connect Pin1(3.3v) (or pin17) of raspberry pi to a 1k resistor.
  2. From the 1k resistor take three wires and connect to three different switches
  3. Connect from switches to pin 11(GPIO 17), pin 12(GPIO 18) and pin 13(GPIO 27).
  4. Now the switch connected to
    • pin11(gpio 17) acts as forward button if evince pdf reader is not running. If evince pdf reader is running then this switch acts as show next slide .
