Ideation
The idea came when I wanted to do something like a lamp that lights different colors and makes a sound, and I can control it with mobile

Tinkercad
Tinkercad
I used Thinkercad to simulate my electronic circuit
Arduino IDE
Arduino IDE
I used Arduino IDE to write and upload my code to my Arduino.
Arduino Bluetooth Control
Arduino Bluetooth Control
The Arduino Bluetooth Control app connects a smartphone to an Arduino via Bluetooth to send commands. It is used for robotics, home automation, and wireless control.
Electric Components for the Circuit:
Electric Components for the Circuit:
Arduino Uno is a small programmable board that reads inputs and controls outputs based on uploaded code.
Connect components to the Arduino Uno and breadboard.
allowing signals to transfer.
Buzzer: Produces sound when powered.
(action component)
breadboard
helps organize connections without soldering.
Resistors (330 Ohm)
Limit current to protect the 7-segment display LEDs.
Ensure proper brightness and prevent damage.
An RGB LED is a light-emitting diode that combines red, green, and blue LEDs in a single package.
( action component )
The HC-05 Bluetooth module enables wireless communication using Bluetooth. It connects to microcontrollers via TX/RX pins and supports both Master and Slave modes. Used in robotics, home automation, and data transfer.
Design/Preparation Process
Design/Preparation Process
I designed my circuit on Tinkercad.
I used the buzzer & RGB LED as the output components and the Bluetooth module as the input components.
I used Arduino Uno as a controller.
I simulate the circuit on Tinkercad.
start writing the code
This Arduino code controls RGB LEDs and a buzzer using Bluetooth commands received through the serial monitor.
1. Setup Section (setup())
Serial Communication: Serial.begin(9600); starts communication at 9600 baud rate.
Pin Setup: pinMode() sets pins 4, 5, 6 (LEDs), and 9 (buzzer) as output.
. Loop Section (loop())
Waits for Input: The code waits until data is received via Bluetooth (Serial.available()).
Reads Input: Stores the received character in incomingData.
Actions Based on Input
Actions Based on Input
If '1' is received, the red, blue, and green LEDs flash in sequence three times.
If '3' is received, the buzzer turns ON.
If '4' is received, the buzzer turns OFF.
If any other input is received, "enter a number from 1 to 4" is printed on the serial monitor.
Development/Implementation Process
Development/Implementation Process
VID_20250311_092035.mp4I made the same connection in reality as Tinkercad; I used jumpers for the wires.
I uploaded the code by USB to Arduino
I connected the Bluetooth module to send and receive data through the mobile app.
Video from Rana🐱I connect the mobile app to the Bluetooth module
and control the Arduino with it
Overcoming Challenges:
Overcoming Challenges:
I face some challenges when I write the code: I have some language mistakes, so I try to detect the mistacks. like geen , should be green
Also, when uploading the code in Arduino, should take off the wires of Tx and Rx, which makes the connection better, and then return the wires in their place
