It just came to me, do you have a power supply beefy enough for all those 8 heavy duty motors? If it's enough only for 1 you have to make a controller to operate them sequentially... It is going to cost a lot.

If you choose the relays and usb, make sure to operate the motors one ar a time or you'll fry the PS.

Really big stuff for a prototype...

[elisom]

The DC power strong enough for all the 8 together.

What is the ULN2003 ?

[4Dcube]

What's the model of the actuator? Just to check its current consumption.

[elisom]

I have 8 actuators

ok, here
https://www.aliexpress.com/item/Multi-function-Linear-Actuator-Motor-DC12V-150mm-Stroke-Heavy-Duty-500N-load-mini-electric-linear-actuator/32610427135.html?spm=2114.40010308.4.9.vbmWrL
is the same motor but with its characteristics written.

Those
-Continuous Current(A):3A(max)
-Voltage(V):12v
mean that for 8 of them you need a power supply of 12V and 3*8=24A, do you have one such?

Also, now that we know the motor's characteristics and the fact that there are no electronics present whatsoever , the problem is fully defined and people can think of solutions.



PS If the idea is to have it work as modular, it is imperative that the design of the actuators driver/controller is to consider sequential driving of the actuators

[elisom]

Right now i am using 6A and it works well. however, i will put separate DC supplier to each module (each 4 actuators).

the stage now is to connect them first to the computer, but no idea yet exactly how.
