Bluetooth RC Car Kit with Arduino Uno & HC-05 - Build a Smooth, Phone-Controlled 2WD Robot

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Turn your smartphone into a precision steering wheel. This kit lets you build a two-wheel-drive car that responds to every tilt of your thumb - not just start/stop. The HC-05 Bluetooth module receives analog joystick coordinates from any Android app, and the Arduino Uno converts them into smooth, variable-speed commands. Instead of jerky on-off control, the L298N motor driver delivers graded PWM signals to each TT gear motor, giving you real-time speed and direction control that feels natural.

What You'll Build

A responsive remote-control car that actually drives like one. You'll assemble a sturdy 2WD chassis, wire the HC-05 to the Arduino's serial pins, and program the logic that maps X-Y joystick values to independent left and right motor speeds. Forward, reverse, smooth turns, and on-the-spot pivots - all handled with code that reads a continuous stream of data, not just single button presses. The result is a vehicle that accelerates gently, corners precisely, and stops without overshooting.

What You'll Learn

• Reading real-time serial data from a Bluetooth module and parsing delimited values inside Arduino code.
• Generating PWM signals on digital pins to control motor speed, and using L298N enable pins to implement forward/reverse.
• Mapping analog joystick ranges (0-255) into differential left-right motor values for smooth turning curves.
• Filtering Bluetooth dropouts and building a robust communication loop that fails gracefully.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11-12 students tackling Arduino in IT or physics practicals will find this a substantial step beyond blinking LEDs. First-year B.Tech ECE/EEE students can use it to solidify concepts of serial communication and PWM before diving into semester projects. ATL Tinkering Lab mentors and Smart India Hackathon participants will value how the kit moves from theory to a tangible, controllable robot within a single afternoon.
