Generating accelerating pulse train

Development Boards Arduino
1

Hello,

Here’s what I have:

Price is right IGT slot machine wheel connected to…

K179 Stepper driver (which controls speed and direction of wheel)

Light control board (controls chasing light speed)

VLT130 AC/DC power supply

TDK-Lambda DSP30-12 power supply

As you can see by the video, the wheel spins albeit slowly. When I manually increase the stepping speed on the K179, the spinning stops and just freezes. My goal is to have this spin fast and then slow down and stop on a random number which I believe I will need some sort of a trigger for.

Goals:

Spin faster without freezing

Have the unit connected to a button when pressed would slow down and stop randomly

I purchased an arduino uno and am looking to connect it to the K179 stepper driver to generate the steps with acceleration/deceleration and random stop. Do you know how do I generate an accelerating pulse train?

Thanks.

For help with the speed problem, you need to provide the details of the stepper motor on the wheel (link to data sheet or product page). For the highest possible speeds, you will need a modern, switch mode stepper driver and a high voltage power supply.
