SUN Tracker Using PIC Microcontroller & Stepper motor

Hi to all today here with a new one Important Project of PIC microcontroller & stepper motor, that is SUN Tracker. Its very useful application for students and as well for Solar penal installation companies (means Industrial application).

Students Learning:

Here is some Learning for Students also like

1. Interface LDR with PIC Controller

2. How to initialize ADC in PIC for different application 

3. How to read analog signal using PIC Controller

4. How to interface Stepper Motor with PIC controller

5. How to use ULN2003A (Motor Driver)

Components list: for Project

• 2 LDR 
• 2 Resister 10k  
• 1 Resister 1k
• 1 PIC16F876 (you can use any PIC controller having ADC)
• 1 ULN2003A
• 1 Stepper motor 6 wire
