Need help with my new project !

Projects General Guidance
1

will begin by thanking you for accepting me to this amazing community.

I am currently in the early stages of the project and I am faced with the challenge of connecting 24 LED types: RGB LED Bead IC Built-In APA106
When I want to control each one separately including light intensity and color and ability to run one by one, group by group or everyone together!!
And 12 engines of the bipolar stepper motor, on which I have to control the direction (clockwise or counterclockwise) and the motor speed.
And I want to connect them to Uno Arduino.

Here are some things I've learned:

  1. I have to provide a separate power for all the components.
  2. I need L298N Dual Motor Controller Modules or similar to connect to each motor.

Here are my thoughts:

I think about Multiplexing and I understand that it is better to use SPI rather than I2C because it is faster and you can give several Parallel commands but I need to use all of them in Digital pin (not analog pin).

I think that for the LEDs there is an IC built-in solution that can receive a digital pulse and change the light intensities Am I right?

I do not have a solution right now about the engine, please your advice.

Sorry for the length of the post I tried to be as accurate as possible and give the right background.

I would appreciate your help

Look for WS2812 LEDS. They come in strips and individual pixels.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

What is your project that requires so much hardware?

Can you tell us your electronics, programming, Arduino, hardware experience?

What size are the stepper motors?

Thanks.. Tom.. :slight_smile:

Number 2 is almost certainly a bad learning. Have a look at Stepper Motor Basics

Hi Tom

Thanks for your welcome response

My goal is to make a mockup for a new project that involved with a 24 RGB LEDs and 12 stepper motors.

I"m a very technical person with a lot of experience in mechanical software computer hardware and a little

a bit in electronic.

The stepper motors are small they are NENA 14 Stepper Motor: Bipolar, 200 Steps/Rev, 35×36mm

Appreciate your help
