Electrical Noise and Servos
August 21, 2010
"Warning! - Servos generate a lot of electrical noise. The PICAXE microcontrollers WILL NOT run correctly if a single power supply is used. This is because the electrical noise will disrupt the operation of the PICAXE microcontroller, constantly resetting it. If noise affects your circuit try soldering a large electrolytic capacitor as close as possible to the microcontroller power pins." - From the AXE030 Datasheet
I am quite confused. Is it saying to use a two power supplies AND a capacitor, or is it saying to use two power supplies OR a capacitor? I noticed that on the AXE024 there is not a seperate power supply used. I apoligize for my large number of forum posts, I am just trying to work out a circuit design.
