Topic: Stepper Motor Not Turning with EasyDriver and Arduino, Only Vibrating (Read 6621 times) previous topic - next topic

It turned out that the power supply was the problem. I connected the EasyDriver power supply to a laptop charger and the motor turned nicely. Now my only question is: What is a good portable power supply (preferably not too expensive or heavy)?

Today, I tried the laptop charger again, but a spark came, so I guess that's too much voltage? Anyways, I still need a portable power supply. Preferably one that I can power all 4 stepper motors with one instead of having to buy 4 of that power supply.

I am changing the stepper motor I am using to this: https://www.pololu.com/product/1206. May you please post a good power source (connected to EasyDriver) for this motor?

That's good.

If it worked before, it isn't. Sparks happen when you have a short circuit.

What, exactly, are you building? Stepper motors are not really intended to be driven by batteries.

I'm building a robot that climbs stairs, so the power source will need to be portable.

Also, I would prefer it to be rechargeable, but if that isn't available, then I don't need it. Do you think lithium polymer batteries would be a good idea? Do you think this would work?: https://www.amazon.com/HitLights-Rechargeable-Lithium-Battery-Strip/dp/B007RQW5WG/ref=sr_1_2?ie=UTF8&qid=1487906283&sr=8-2-spons&keywords=12v+rechargeable+battery&psc=1

I was wondering: can I use ordinary 12V batteries, or do those not work with EasyDrivers and stepper motors? Also, can i use a battery pack with multiple batteries in one like this one?: https://www.amazon.com/CO-RODE-Battery-Holder-Wired-Switch/dp/B00VE7HBMS/ref=sr_1_8?s=electronics&ie=UTF8&qid=1487991928&sr=1-8&keywords=12V+battery

Could I use 2 9V battery holders and combine the outputs together to attach to the EasyDriver?

Here is the battery holder:

Here are the batteries:

If I can you that, what would be the best way to connect metal wire to the barrel plug?

Yes. Just don't expect anything useful to happen.

What part of STEPPERS NEED A LOT OF CURRENT don't you understand? 9V batteries are a good deal - for the manufacturer and the retailer. They are a crappy deal for the consumer - they offer the lowest current/dollar ratio of any battery on the market.

In that case, can I use 8 AA batteries like I mentioned before?

You are welcome to try. I have my doubts about you being satisfied with the performance.

What's wrong with AA batteries? Do they also have low current?

geko_arduino

had same problem, wiring ok, separate elec supply.
solution was to import the Libraries
from menu ( sketch ? in french Croquis), include library, import a zip , take it from CD
then libraries again, find the new imported library

#include <Stepper.h>

#include <IRremote.h>
#include <IRremoteInt.h>

in my case was missing the last one.
works ok now...
good luck you who enters here, there is still hope!
