Hi,
OPs pic;
Very nice.
Servos can be a doddle.
- Servos can require more an an AMP to run, check specs.
- Servo needs separate supply from the controller.
- The Controller gnd MUST be connected to the Servo Supply gnd.
- Servos consume current even when signaled to a fixed position if the servo has to work against a load torque.
- The cheaper the servo, the less each servo behave to spec, in particular, 0 to 180, might be 10 to 170.
Tom...
I can make one spin at will...............lol
The problem is I have built a parrot. Yes a mechanical burd... It has 4 kit servos (SG90s) I had to install as the build went on and are now inaccessible. How did I know they dont actually start at 0 Lol..........
I need two to run off a joystick (look left and right/ Look up and down).
I need one to run off the press button in the joystick (mouth open and close) and one separate button to flap the wings.
The nearest I could find program wise was this with lines added for the 'W' axis but Im having trouble getting rid of the serial monitor bit. everytime I try and delete it the damn thing wont verify. If I leave it in the damn thing comes up with faults on my W axis. Its driving me to distraction.

I dont think it helped it was in Portuguese
What do you think........... Am I onto a loser
