The IoT (Internet of Things) Smart Bulb Project is a captivating endeavor that allows you to create a cutting-edge smart lighting system that can be controlled remotely using a mobile app. This comprehensive guide will delve into the key components, technical specifications, and step-by-step instructions to help you bring your IoT smart bulb project to life.
Hardware Requirements
NodeMCU ESP8266
The heart of this project is the NodeMCU ESP8266, a low-cost microcontroller board with built-in Wi-Fi capabilities. The ESP8266 features a 32-bit Tensilica Xtensa LX106 CPU, operating at a clock speed of 80MHz, and comes equipped with 128KB of RAM and 4MB of flash memory. This powerful yet affordable microcontroller is perfect for IoT applications, as it allows seamless integration with various sensors and actuators.
Relay Module
To control the bulb, you’ll need a relay module. Relays are electromechanical switches that can handle high-voltage and high-current loads, making them ideal for controlling devices like light bulbs. The relay module used in this project typically features a 5V coil and can switch up to 10A at 250VAC or 30VDC.
LED Bulb
The LED light bulb is the primary component that will be controlled in this project. It’s important to choose an LED bulb that is compatible with the voltage and current specifications of your setup. A standard 5-10W LED bulb should work well for most applications.
Power Supply
To power the NodeMCU and the relay module, you’ll need a 5V power supply. This can be a USB power bank, a wall adapter, or a dedicated power supply module.
Breadboard and Jumper Wires
A breadboard is used to easily connect the various components, while jumper wires are used to make the necessary connections between the NodeMCU, relay module, and the bulb.
Software Requirements
Arduino IDE
The Arduino IDE is the software used to write and upload the code to the NodeMCU ESP8266 board. It provides a user-friendly interface and a wide range of libraries to simplify the development process.
Blynk App
Blynk is an IoT platform that allows you to create a custom user interface to control your IoT devices remotely. The Blynk app provides a drag-and-drop interface for designing your control panel, and it seamlessly integrates with the NodeMCU board.
Circuit Connections
- Connect the positive and negative terminals of the 5V power supply to the breadboard.
- Connect the positive and negative terminals of the relay module to the breadboard.
- Connect the “IN” pin of the relay module to the D0 pin on the NodeMCU.
