Hello, in this project I will show you how to transform a simple RC boat to Bluetooth controlled through your Android smartphone!
In my rc boat I chose to build my own Arduino-based circuit because Arduino uno board doesn't fit inside it! But, in this tutorial, you can find an Arduino uno breadboard schematic so you can build it very easy ;)
Before starting, make sure that you have:
- Arduino uno board
- L293D motor driver
- HC-06 Bluetooth module
- RC Boat that can fit all the above !
Optional you will need 1x1MOhm & 1x100KOhm resistror to add a battery level control function.
For power, you can use the existing batteries (4x 1.5V AA), or replace them with a LiOn rechargeable battery pack.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Two Propeller Navigation System
On simple RC boat toys you will find a "two propeller navigation system".
That means you don't need a rudder for changing directions. You can find more details here
Step 2: Breadboard Schematic
Make sure to build your circuit first on breadboard to test it ;)
You can use battery from 6V and adove.
Step 3: Code
Download and open file with Arduino ide. Read every line of code (+comments) to understand how it's working and then upload it to your Arduino uno board!
Step 4: Android Bluetooth Controller
To control your new Bluetooth Boat , download and install this android application:
Tip: First enable Bluetooth and establish connection with BT module. (ex. HC-06, password 1234)
Use "Help & info" button if you can not understand how it is working.
Accelelometer function is under developing, use with attention!
Step 5: And Final...
Now you can put your circuit in RC Boat!
Hope that you like it!!!
