- 4. Introduction In this project, we make use of Bluetooth technology to control our machine car. We do not call this a robot as this device does not have any sensors. Thereby, senseless robots are machines. In this we write a program into the Arduino microprocessor. Arduino car contains an Arduino microcontroller with basic mobility features. In this project, we make use of Bluetooth technology to control our machine car
- 5. After doing this only we can say that we have been able to create as per our goal described.The device can be controlled by any smart device with android The major reason for using a Bluetooth-based tech is that we can change the remote anytime – mobile phones, tablets, and laptops and physical barriers like walls or doors do not affect the car controls. 01 02
- 6. Tools Required: Chassis of Car Arduino UNO L293D Motor Driver Jumper wire Battery Switch Bluetooth Module LCD Display
- 7. The main body of the car consists of the chassis. there will be four motors for the four wheels which will lead down the car. Chassis: The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino. cc. The board is equipped with sets of digital and analog input/output pins that may be interfaced with various expansion boards and other circuits . Arduino Uno:
- 8. Jumper wire: A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of thcable, with a connector or pin L293D Motor drive H-Shield: The Motor Driver is a module for motors that allows you to control the working speed and direction of two motors simultaneously. This Motor Driver is designed and developed based on L293D IC. L293D is a 16 Pin Motor Driver IC. This is designed to provide bidirectional drive currents at voltages from 5 V to 36 V. Rotation of a motor depends on the enabled pins.
- 9. A battery is an energy source consisting of one or more electrochemical cells and terminals on both ends called an anode (-) and a cathode (+). Here for the project, a 9V battery has been used. Battery: A switch is used for turning on the power of the vehicle. It controls the battery connection of the vehicle. Switch:
- 10. 7 HC-05 6 Pin Wireless Serial Bluetooth Module is a Bluetooth module for use with any microcontroller. It uses the UART protocol to make it easy to send and receive data wirelessly I2C LCD is an easy-to-use display module, It can make the display easier. Using it can reduce the difficulty of making so that makers can focus on the core of the work. Bluetooth Module: LCD Display:
- 11. Basic Structure Building: we have connected this 4-wheeler with Arduino and Bluetooth Module/ There is an Android application that is already installed in the remote device. We send our instruction to the vehicle with that application, that application is connected with the module in the vehicle. Bluetooth module transfer that instruction as a signal to the Arduino, and Arduino works with that signal. In the Arduino, we have installed the code which can work with the signals and convert those instructions to the pre-defined signals. Signals were transferred to the motors, and the car started running.
- 12. Pin Daigram & Connection:
- 13. Wireless Control: Bluetooth allows you to control the car remotely without any physical wires. You can operate it from a distance, enhancing convenience and flexibility. 1. Wide Range: Bluetooth provides a decent range for communication (typically up to 30 meters or more). This means you can control your car from a considerable distance. 2. Ease of Use: The project utilizes an Android device with an inbuilt Bluetooth module as the remote control. Most people are familiar with using smartphones, making it user-friendly. 3. Cost-Effective: Arduino boards and Bluetooth modules are affordable components, making this project accessible for hobbyists and students. 4. Advantages:
- 14. Limited Range: While Bluetooth offers decent range, it’s not suitable for long-distance control. Walls, obstacles, and interference can affect the signal quality. 1. Latency: Bluetooth communication introduces some latency due to data processing and transmission. Real-time applications may experience slight delays. 2. Power Consumption: Bluetooth modules consume power, which affects the overall battery life of the car. Efficient power management is crucial. 3. Security: Bluetooth connections can be vulnerable to unauthorized access or interference. Ensure proper security measures to prevent unauthorized control. 4. Complex Pairing: Pairing the Bluetooth module with the controlling device can sometimes be tricky, especially for beginners. 5. Disadvantages:
- 15. Conclusion This project consists of a basic prototype of a Bluetooth control car above stated. The prototype car can recognize commands from users and can turnthe car left, right, and stop with great accuracy. It can be further improved by using different sensors like ultrasonic or infrared and with various levels of coding. Our Bluetooth control car has a range of 10-20 meter with the mobile Bluetooth controlling system.
