I have been experimenting with the servo sweep example, however I am about to undertake a much larger project where I wish to run a sequence of 20 servos that will basically rotate in step to a controlled amount of degrees.
However I am unsure about the best way to do this and was hoping that someone could advise.
I am using a arduino mega board and the servos are HS-322HS Standard Deluxe servos.
If more information is needed just let me know.
Cheers
If they have to rotate exactly in step you should be able to drive them from one pin (fanout permitting).
Sorry I should of explained more clearly, there needs to be a delay between each servos movements
Checkout the Servo library documentation - I think it can do several servos per timer, the Mega has about 6 timers, so it all depends on what 'several' actually is...
The standard servo library can do 48 servos on an Arduino Mega so you should have no problem.
Due to space i am unfortunately down sizing the project to 12 servos. However I am hoping someone could give me advice on the best way to power this.
Each servo requires 6V to be able to run at its full speed. I have never tried connecting a external power to arduino and would really appreciate some guidance on this and the best way to power all 12 servos.
The servos have three wires: Power, Ground, and Signal
Connect your 6v power supply to Power (+) and Ground (-). Connect the Arduino to Signal (data pin) and Ground (ground).
And that 6V supply will be enough to run all 11?

Maybe, maybe not. You've told us which servos you have, which defines how much current you need to supply, but you haven't told us anything about the power supply, except that it is 6V.
sorry my mistake, im currently using a regulated bench power supply, with output voltage adjustable range between 1.0 - 20Vdc and a output current adjustable range of 0 - 5A . If i have missed anything just let me know.
