+# 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
