Ok, I've always been more of a software guy than an electronics man. Haven't really done any electronics for a year either and tonight I'm understanding why I didn't miss it that much...
My servo battery pack died this evening and I figured slaughtering a 6V adaptor and connect the whole thing to my breadboard would be piece of cake but boy was I mistaken.
Here's the setup:
Vanson Regulated 6V AD/DC 400mA
Power and ground connected to Vanson adapters power and ground, signal connected to PORTD on MCU (stk500 board)
Ground from PORTD to ground from Adaptor and Servo. Signal from PORTD to servo.
I must be missing something in the setup here, since the servo refuse to move. If I plug in a batterypack instead of the adaptor (same setup), everything is fine. I've checked voltages with multimeter and it's the same for batterypack and adaptor. Also checked with respect to both ground on adaptor side and from stk500 side to make sure ground is common. Any ideas? I'm going nuts here...
