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.
