general idea

• servo connected to pin 19 on the pi
  • it will allow the camera to look up and down
• use go-rpio
  • it has a hardware PWM implementation
• mechanical design will have limits
  • set the limits in roverd config
• control the servo from the web browser
  • expose both a slider and buttons for "nudging" it up and down

verification of functionality before full implementation

• make sure that the go program can properly use the GPIO correctly before full implementation
• modify the roverd installer to add the needed stuff to enable PWM access
