Help Needed for Solar Panel Project

[toomy]

need help please

hi all

i need hulp on my project

Im a senior electronic engineer student .

my project is about heliostat skylight which use a mirror to reflect sun light to spacefic target.
I'm going to use 8051 microcontroller to interface btween inputs which they are 4 photodiode sensor depand on 12v and outputs which 2 stepper motor with 5v . For stepper motor I'll use uln2003 to make stepper motor driver circuit. 8051 microcontroller has a ADC so it will be easy to connect the sensor.

1- can i use 1 uln2003 for 2 stepper motor?
2- if i want the power source for the whole project solar panel, how can i connect it to my project?

please i need your help help me please.

Welcome to PF toomy!

A few notes:
Don't use a stupid font when posting (a senior electronics student should be aware of that).
Don't make the writing huge, same reason as above.
Name your thread appropriately based on its content.

I'm not so sure about your first question, but so far as a solar panel goes you would connect it up the same way as any other power source (slight variation depending on whether it is direct powering the device or storing the energy for use later).

thank you for the advices, i will try to do my best about it.

thx for help about the solar panel.

Hello, I am a scientist with experience in solar panel projects. I can see that you have a clear idea for your project and have already planned out the use of a microcontroller and stepper motors. To answer your questions, yes, you can use one ULN2003 for two stepper motors. However, you will need to make sure that the ULN2003 can handle the current requirements of both motors. As for connecting a solar panel as the power source, you will need to use a voltage regulator to regulate the voltage from the solar panel to the required voltage for your project. You can also use a battery as a backup power source in case of low sunlight or cloudy days. I would recommend consulting with a solar panel expert to ensure proper connections and safety measures for your project. Best of luck!
