HANDS-ON PROJECT
PROJECT NAME: Smart Lamp Using Bluetooth Technology
Components Needed:
● Arduino Uno
● HC-05 Bluetooth Module
● LEDs (Red, Green, Blue - RGB LED recommended)
● Resistors (330Ω for LEDs)
● Jumper Wires
Objective:
Students will be able to create a smartphone-controlled lamp using Bluetooth communication.
Step-by-Step Instructions
Circuit Setup
Steps:
1. Connect RGB LED anode to Arduino digital pins (e.g., Red → 3, Green → 5, Blue → 6).
2. Connect 330Ω resistors to each LED pin.
3. Connect HC-05 module as described earlier.
Testing the Circuit
● Check if the LEDs turn on and off when controlled from Arduino.
● Verify if the Bluetooth module responds to serial data.
