nice dude the reaction time is very fast

Thanks!

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

@Khalid1349

Probably, yes.. :)

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.

dude great work..can u let me into d details like the logic behind this...d circuit and the programme for the micrcontroller.am also doin a solar tracker as my project..my id is rnj.143@gmail.com

Hei, thank you for the comment. This is my main ID, wikhuuw is my sister's and she helped me uploading the video, so yeah :P...

What kind of solar tracker are you going to make? Is it also a dual axis solar tracker?

I used some electrical circuits as you can see in the video. 2 motor driver circuits for 2 stepper motors, Analog to Digital Converter circuit using LM 3900, voltage regulator circuit using LM 723 to produce output voltage of about 5 V to be used by...

... 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?
