Bluetooth Controlled Car Kit with Arduino Uno + HC-05
Bluetooth Controlled Car Kit with Arduino Uno & HC-05 – Drive It from Your Phone
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 remote control and command a custom 2WD car with variable speed—no prior robotics experience needed. The HC-05 Bluetooth module listens for commands from any Arduino-compatible app, while the L298N motor driver translates them into smooth forward, reverse, and turning movements. The kit includes everything you need, from the Arduino Uno brain to the durable chassis and long-lasting 18650 batteries. Perfect for CBSE Class 11-12 computer science projects or simply exploring Bluetooth-controlled robotics at home.
What You'll Build
A fully functional 2-wheel-drive robot car that responds instantly to direction and speed commands sent from your phone via Bluetooth. Assemble the sturdy 2WD chassis, mount the motors and caster wheel, wire the L298N driver and HC-05 to the Arduino Uno, then load the code and watch it zip across the floor under your control. You'll gain the confidence to tweak the chassis design, add sensors later, or even turn it into an obstacle-avoidance bot as you master the fundamentals.
What You'll Learn
- How to establish wireless serial communication between a smartphone and Arduino using Bluetooth (HC-05 module)
- How to control DC motor speed and direction with an L298N driver through PWM signals
- How to manage power distribution from 18650 Li-ion cells to motors and microcontroller safely
- How to debug a multi-component embedded system using the serial monitor and Bluetooth AT commands

Who This Kit Is For
This intermediate kit is built for Class 11–12 CBSE students tackling Bluetooth-based computer science projects, B.Tech ECE/EEE undergraduates prototyping for hackathons like Smart India Hackathon, and ATL Tinkering Lab mentors looking for a ready-to-assemble robotics module. It’s equally suitable for hobbyists who have dabbled with Arduino and want to move into wireless control.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the kit for instant access to our AI build companion, or message us on WhatsApp for expert help within hours.
Do I need to solder anything?
No soldering is required. All connections use jumper wires and screw terminals on the L298N, making assembly completely plug-and-play.
Which phone app should I use?
Any Arduino Bluetooth controller app (available on Play Store / App Store) works. We provide a recommended app name and configuration instructions inside the kit.
Can I power the Arduino directly from the 18650 batteries?
Yes, the kit includes a 2-cell 18650 holder. You can power the Arduino via its Vin pin (7–12V), and the motors through the L298N's supply input, all from the same battery pack.
HC-05 receives phone app commands. L298N drives 2WD car at variable speed.
