Automatic LED Control Using Solar Power and Battery Backup

Image
  Introduction With the growing emphasis on renewable energy, integrating solar power into everyday applications is a step toward sustainable living. This project demonstrates how to build an  automatic LED control   system  using a solar cell, diode, switch, LED, photoresistor, and an NPN transistor. The system ensures that the LED glows when solar power is available, while the battery remains off, effectively managing energy usage. Components Required Solar Cell (5V or higher, depending on LED requirements) Diode (e.g., 1N4007 to prevent reverse current) Switch LED (Light Emitting Diode) Photoresistor (LDR - Light Dependent Resistor) NPN Transistor (e.g., BC547) Resistors (as per required values) Battery (Rechargeable, 3.7V or 5V) Connecting Wires Breadboard How It Works Solar Power Supply: The solar cell converts sunlight into electrical energy, providing the primary power source for the LED. Photoresistor (LDR) Detection: The LDR detects ambient light levels. Dur...

USING MOBILE BULB IS [ON/OFF].

Image
  Introduction In today's era of smart homes, automating appliances has become easier and more accessible. This project demonstrates how to create a simple yet effective  smart bulb control system  using an   Arduino , ,   HC-05 Bluetooth module, a relay , and a   custom smartphone app . The goal is to allow users to control a bulb remotely through Bluetooth communication Components Required Arduino UNO Breadboard HC-05 Bluetooth Module 5V Relay Module Bulb with Holder Smartphone with Custom App Connecting Wires Power Supply How It Works Bluetooth Communication: The smartphone app sends an ON or OFF command via Bluetooth to the  HC-05  module. The  HC - 05  transmits this data to the  Arduino. Signal Processing by Arduino: The  Arduino  reads the received signal and processes it. If the signal is "ON," the relay is triggered to turn the bulb on. If the signal is "OFF," the relay disconnects the circuit, turning the bulb of...
