Hello there, this is my first time ever working with the Proffie Board or motors. I am currently working on a project that requires a very, very fast DC micro motor (about 2,000 rpm) I am wondering if a micro controller is need to control the motor or if it can be done natively on the proffie board. I don’t know how to code or do anything like that. If anyone can help that would be great. If you are able to help try to make it as simple as possible. Thanks a lot everyone one that may help out with this project.
It depends on the motor. If it’s just a DC motor with a positive and negative terminal, you just wire it up like it’s an accent LED, and control it accordingly. Doesn’t matter what color you pretend it is, so long as you use that same color in the blade styles that control it.

Would I be able to spin it both ways and have multiple fonts and be able to switch bc this is for a lightsaber project
No, proffieboards do not have an H-bridge, so you would need additional components to do that.
You can however control the speed of the motor.
Appreciate it man once I get the materials do you think you could write a code for it for me since I have no idea what I’m doing
It’s literally the same as driving a LED.
Black = off, gray = slow, white = fast
would a micro controller be needed or could it be done with just an h bridge. for this use I would want it to spin one way for a certain time and then spin the other at the same amount of time
There are lots of options. Some would require some coding, some is simple enough to just do some styles to control it.
Someone used a chip that had one “direction” input and one “speed” (where speed used PWM for control.) something like that would be very simple to hook up.
PS, you might want to check out this thread:
They are using this driver I think:
since i need to power both the board and motor and have limited space would i be able to use 14250 3.7v li ion batteries or possibly 23a battery since they are 12v and still get same or close to same performance if i were using like an 18650 battery or with the 23as would the board get fried or just not work and perform well or long enough
or also like 2 18350 batteries
You can’t give the board itself more than 5 volts (the actual limit is 5.5 volts, but you have to have some margins.) A 3A buck converter would work for feeding the board from a 12V battery.
So the 2 18350 batteries would work if one powered the motor and one powered the board
Why not just one at that point?
Unless you’re saying to wire them in series and split in the middle for the board? You’d need a balancing charger then, at least.
Lithium ion cells have a 3.7v nominal voltage.
I am using a micro motor that is 1.5-3.7v so I was thinking to use one 3.7v battery for each the lights and motor but are you saying I could just use 1 for both or should I use something else like a 9v or something.
Oh I thought you were saying to use two because the motor needed ~7v
Yeah definitely just use a single cell if all your voltages are around what it’ll output.
You’ll need some sort of step-down for that motor it sounds like, but if you’re going through the trouble of adding a driver board to be able to control direction that won’t be much more of a hassle.
Thanks so much bro but just want to make sure you said only one battery and it should work
Well, I said “One cell.”
A battery may be made of multiple cells. You want a single-cell battery. But yes, it sounds like a single(-cell) battery would work
You literally just saved my project thank you so much RyRyog25
