RC Boat With HC-06 Bluetooth Module

I will show you how can you make a RC BOAT but it just for 25 meters distance! i use bluetooth module but if you want to use Nfr it would be healty for long distance.

Here is a list of parts that i used to make this project:

• DC motor and propeller
• L298 motor driver
• Arduino UNO
• HC-06 Bluteth module
• 18v battery and voltage regulatör
• Servo Motor
• Jumper Wires

ı use a battery which output is 18v so ı use regulator for decrease the voltage !

The code has explanations of code functions. You will easly understand it. If you have a problem , you can contact me.
