How TO Clean Up

Ken_tn

·· Now that I have my LCD Working. I have a servo that I also control, but wheneve I make the servo move to a new postion the LCD Blinks during the movement. Is there something I do about this? As you can tell just a beginner and still have lots to learn. I was thinking maybe some kind of filter to keep the voltage to the LCD Constant?

··· Any help would be greatly appreciated.

You need a better or a separate power source for the servo. Servos can draw a lot of current when they're just starting to move, on the order of 1 Ampere each. Best thing to do is to have a separate 6V power supply for the servo, capable of delivering at least 1A. Connect the negative side of the supply to the ground of your Stamp / LCD supply.

You can use a large electrolytic capacitor as a filter for the servo, something like 1000uF or more connected across the power supply leads of the servo, close to it. Remember that the capacitor has to have a voltage rating modestly larger than the voltage of the power supply for the system.
