  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. ...

  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 off. Relay Control: The relay a...

 Nutrients in Foods (Using Arduino and Scratch with Bluetooth Control) 1. Introduction ● Introduction: Nutrients in Foods Nutrients are essential substances found in foods that are necessary for the proper growth, development, and functioning of the human body. They provide energy, build and repair tissues, and regulate various bodily processes. A balanced diet containing the right amount of nutrients helps maintain overall health and prevents diseases. There are six main types of nutrients found in food: Carbs – The main fuel source for the body, commonly found in grains, fruits, and vegetables. Proteins – Crucial for body repair, muscle growth, and overall development, present in meat, eggs,                          legumes, and dairy products. Fats – Provide long-lasting energy, support cell function, and aid in absorbing key vitamins, found                    ...

Project Name : Making a keychain with your name using Tinkercad... Step 1: insert the box in workspace. and then resize it     length:60mm.     width:15mm.              and then thickness of the box is 3mm.               It looks like the picture below. Step 2: insert the cylinder on the workspace.  and then resize it.    length:6mm.    width:6mm.              and height of the cylinder is 3mm.              It looks like the picture below.              We are going to use the cylinder to make a hole in the kitchen.            then align the box and the cylinder in one line. Then align the cylinder            where you want the hole for the keychain to be. and then the select the        ...
