I am a computer programmer and not an electrical engineer so please pardon my ignorance in your field. I am interested in turning a knob 5 times per day, the fifth turn is for returning to the neutral position at the end of the day using a servo (unless you know of another method). I basically want to set a programmable timing device capable of 5 settings in a 24 hour period (alarm clock maybe?) that will deliver the correct voltage and pulse length(s) to a servo and cause the servo to turn x number of degrees at each time setting. The fifth setting returning the servo to the neutral position. Any ideas how I can achieve this? It is meant to turn a small knob on an electronic ballast for a set of lights to simulate the phases of sunlight throughout the day without opening the ballast and messing with the internal circuitry. Thank you.
