Topic: Project 10 with a Bigger Motor not Working (Read 5029 times) previous topic - next topic

So I just finished Project 10 (Zoetrope) in the Arduino Projects book, and I wanted to see if I could use a larger motor. I tore apart my cordless drill and got an 18 V DC motor. The battery I'm using is also from the drill, 18 V and 1.3 amp-hours. I plugged them in the same way that the project specifies. When I try running the program the motor will turn on, but it won't begin spinning no matter how far I turn the potentiometer. I'm thinking it's more of a coding issue? I've got a picture of the setup for reference. Could really use some help!

Oh please stop.
Unless you like letting out the magic smoke that makes electronics work.
The chip that you are using probably has a max of about 1a per channel.
That motor pulls MUCH more than one amp.

You need to look into motor drivers that can handle the larger current draw.

So you think it's a coding issue...but you haven't posted any code?

But that's o.k. because as vinceherman says it's a power problem, nothing to do with coding. You have a motor driver IC that can handle less than 1A and motor that needs a lot more than that.

Many modern cordless drills use brushless DC motors.  Those need to be controlled with a dedicated driver chip, not like a regular DC motor that just takes power

Thanks for the advice, this is all pretty new to me and I was unaware of how essential a motor driver is.
