Servo Contoller, Timed Multiple Servo Control, (TIPS ONLY)

Forum topic

Anyone got any tips on how to do this?

Any idea?

I'm trying to make a servo controller which can control at least 12 servos, and it's timed with a 555 timer IC.

Any idea how I'm able to do that?

I'm only asking for tips, no solid information.

I'm doing this in DIY.

‹ I found this website while searching for stepper motor control schematics. I/O expanders, instead of having only 8 outputs, are there any of them which have more than 8 outputs? ›

1 555 can control 1 servo but you might be pushing it to control 12 servos without 12 555s.

Why can`t you use a micro? An atmega168 costs about $5 and can control 12 servos with the right code.

Dont think it´s a rich mans toy, not that expensive... And why a 555 timer???

I told you, (Not litterally) I'm from a small village as in I've get AU$20 a week.

I can't afford shipping lol!

or work extra in a gas-station... Think you will get your servo motions quicker working extra then try to figure it out yourself...

Oups- sorry, did´nt mean to be rude...

It´s based on a micro-controller. You can program any microcontroller to do the job, and if it´s not enough with one, take two and make them talk to each other, either through i2c, rs485, plain pulses or serial. Any microcontroller is up to the job.

• Does each servo need independant control?
• What exactly will be providing input for the servos? A micro controller? Sensor input? Direct user interface?

I want servos to be moving simultaneously instead of one at a time.

TIPS ONLY.

Will they all move in sync, or will each be able to move in a different way to the rest?

Well obviously you can connect all the servo control inputs together if they're all doing the same thing.
If they're independant you could use a demultiplexer to split your control signal into many outputs, effectively giving you the ability to control many servos from just a few outputs.
