Started to spin 8 servos at a time ...it went really slow and even had to unplug the other 8 cause nothing was working anymore...powersupply was hanging at 2A.
I have some questtions:
Is the Uno capable handling the data ?
Am i using too heavy load servo's ?
Is it because i didnt use a capacitator ?
The guide writes i have to use a 1600 uF capacitator. if so ...should 1600 uF do the trick or which one is safest to use. Is see a lot of different capacitators dont really know which one to use....I found 6.3 volts and 1500 or 1800uF.
A servo is pretty power hungry, it can draw 1A with ease. And a stall current of 2A isn't even weird for a small servo. According to this your MG995 has a stall current of 1,5A. So for 16 servo's you're going to need a beefy beefy power supply if you want to control them at the same time. A cap isn't going to fix that... It may need a little if you're on the edge but with 16 servo's on a 2A supply you're wayyyyyyyy over that edge
aa thx for your reply ...so the best way is to use lower power servo's... or is it weird to use them with a minus 16amp powersupply as i already bought them.
I doubt you want lower power servo's because I imagine you bought them with a reason (aka, could do what you want). So unless you want to use super tiny servo's just use these but:
a) or get a bigger PSU
b) or don't move them all at the same time*
c) or don't move them that quick (only take small steps)
d) or all of the above
If you really need to drive 16 of those servos at the same time you need a power supply that can deliver around 20A and I'm not sure if that servo board can handle that much current.
Even if you switch to lower power servos like SG90s for 16 you're still going to need around a 12A minimum power supply.
Unfortunately most of the tutorials and videos show lots of servos just sitting on a desk not connected to anything. But as soon as you put a load on a servo, like making it move something, then the current it takes goes right up. As it is just trying to start moving from rest the current is effectively the Stall Current for a short while.
