LDR base solar light tracking system using Transistor DIY project
Project Title: LDR-Based Motor Driver Circuit using Transistors Objective: To implement light tracking solar system. Components Used: Component Quantity Description LDR (Light Dependent Resistor) 2 Senses light intensity BC547 NPN Transistor 1 Used to switch current based on LDR1 BC547 PNP Transistor 1 Used to switch current based on LDR2 Resistors (100Ω) 2 Limits current to base of transistors DC Motor 1 Rotates when either transistor conducts Power Supply 1 +5V Battery or adapter Circuit Explanation: This is a dual-LDR sensor-based motor control circuit using two NPN transistor (Q1 ,Q2- BC547) . The two LDRs (LDR1 and LDR2) act as light sensors that detect ambient light levels and contr...
