Help Needed for Solar Panel Project

Click For Summary

Discussion Overview

The discussion revolves around a project involving a heliostat skylight system, which utilizes mirrors to reflect sunlight to a specific target. The project incorporates an 8051 microcontroller, photodiode sensors, and stepper motors, with a focus on interfacing components and power supply considerations, particularly using solar panels.

Discussion Character

  • Technical explanation
  • Homework-related

Main Points Raised

  • The project involves using an 8051 microcontroller to manage inputs from four photodiode sensors and outputs to two stepper motors.
  • The participant inquires whether one ULN2003 driver can be used for two stepper motors.
  • There is a question about how to connect a solar panel as the power source for the project.
  • One participant suggests that connecting a solar panel would be similar to connecting any other power source, with some variations depending on the setup for direct powering or energy storage.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the first question regarding the use of one ULN2003 for two stepper motors, and the discussion on solar panel connections remains open with varying perspectives.

Contextual Notes

The discussion does not clarify specific electrical requirements or configurations for the components involved, and assumptions about the solar panel's specifications and integration are not detailed.

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).
