Phonix V1.0 (A Bluetooth Controlled Car)

Phonix v1.0 is a bluetooth control car. I had made it to participate in the "Speed Racing" competition of my university. It is mainly a arduino based project. It's unique chassis design enables it to operate in both normal and upside down position. Speed and Direction of the car can be controlled by a android app, which is also designed by me.

Supplies

1. 1000rpm DC gear motors
2. L298N motor driver
3. Arduino Uno R3
4. HC-05 Bluetooth module
5. Li-ion Rechargeable Battery
6. Battery Holder
7. Jumper Wire
8. Wheel
9. Hex Coupler
10. Switch
11. Motor Mounting
12. Custom made chassis
13. Nut-bolts

Step 1: Make Chassis and Mount Motors

A custom-made chassis was made and motors were mounted on the chassis with the help of motor mountings. Wheels were connected with motors through hex-coupler.

Step 2: Electric Circuit Design and Connecting Components

All electric components were connected with the help of jumper wires according to our circuit design.

Step 3: Coding

Uploaded the arduino code (attached here) to our micro-controller (Arduino Uno).

N.B: Rx and Tx pins must be disconnected while uploading code.

Step 4: Application Design for Controlling the Car

I made an app (Phonix_V1) with the help of MIT app inventor to control the car with an android device. Block code for MIT app inventor is attached here.

Step 5: Test Drive

I tested the car to drive with an android device and it was working perfectly.
