Help Needed for Solar Panel Project

AI Thread Summary
A senior electronic engineering student is seeking assistance with a heliostat skylight project that utilizes a mirror to reflect sunlight to a specific target. The project involves using an 8051 microcontroller to interface with four photodiode sensors and control two stepper motors via a ULN2003 driver circuit. The student inquires whether one ULN2003 can drive two stepper motors and how to connect a solar panel as the power source. Responses suggest connecting the solar panel similarly to other power sources, with variations based on direct use or energy storage. The student appreciates the advice and plans to improve their post formatting.

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.

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...
Hi. I noticed that all electronic devices in my household that also tell time eventually lag behind, except the ones that get synchronized by radio signal or internet. Most of them are battery-powered, except my alarm clock (which runs slow as well). Why does none of them run too fast? Deliberate design (why)? Wrong temperature for quartz crystal? Decreasing battery voltage? Or just a coincidence?
