My knowledge in electronics is very basic right now because I have just started to take an interest in it so I can learn how things like RC vehicles work better.
I found a tutorial of making a servo controlled LED on/off switch online from http://www.zerorc.com/how-build-servo-led-driver and have used that as my starting point.
What I want to be able to do is use a 3-way switch on the radio for off / low / high (0v / 2v / 3.3v white LEDs being used) and this is where it goes beyond my knowledge.
I am using a Futaba S3004 servo and have found the following websites containing information about the servo:
http://www.seattlerobotics.org/encoder/200304/Futaba S148 Servo mod for PWM.htm
http://www.teamkiss.com/antweight.html
Before I cut off the potentiometer, I measured the DC output at -4.5v, 0, 4.5v depending on the position of the switch. I then cut off the potentiometer, used jumper wires from the 3 posts to a breadboard so I could experiment with different resistor values to accomplish my goal.
The closest I reached with the limited number of resistors I have on hand was -1v / 4.8v / 4.5v.
Any help would be greatly appreciated
