Thanks Robin2. Maybe i'll try a motor dc with motor shield someday for safety
Any ways to make a servo continue it last pos after power off.
what is yoru servo's interval ? i am using 2-10 V servo for turner. when the 2 v output from pwm to servo, the servo is closed, (or 0V) , when 10V, servo opened.
1000us to 2000us for 0 and 180 degrees.
I think that would normally result in ~90 degrees of rotation in a hobby servo, at least that is my experience.
That's not how servos work, at least not here in Arduino-land with hobby servos that I've seen. The pulse is always 5V (ok, 4.8 to 6V), and at a length of 1000us to 2000us for 0 and 180 degrees.
