  • @karthikpatnaik207

    Thanks!

  • nice dude the reaction time is very fast

  • @Khalid1349

    Probably, yes.. :)

  • I think the motors/electronics consume more energy compared to production from the solar cell:)

  • The most expensive parts are the solar panel and the stepper motors. They cost about $200. You will need a microcontroller, a motor driver circuit, and a signal conditioning circuit of the sensors. I used LDRs for the sensors. They are not really accurate and you might want to use photo diodes instead for better accuracy.

  • dude what was the overall cost for making this apparatus

    and just tell me what all other appararus was required

    Sorry for the late response. I used 5-phase stepper motors for this project, which actually make things much more difficult. I suggest you using bipolar or unipolar stepper motors if you want to make a solar tracker similar to mine. The problem is, using motors as the actuators in a medium size solar tracker just like mine poses some problem. You need a mechanism to hold the solar panel so it doesn't fall down when the motors are no longer supplied with power.

  • hi there.. i,m doing this project, would you please provide me a bit more info about this project like source code and schematics please.

  • ... the motors, ADC circuits, and the microcontroller..

    For the microcontroller, I used assembly language.. The logic of the program is a bit confusing because I used a multiphase (pentagon shape) stepper motor which has 5 input cables (unlike other stepper motors such as bipolar and unipolar stepper motors). If you want some simpler logic, try not using mutiphase stepper motor..

    Maybe you can tell me a bit what is your current plan with your project?
