The process of this Bluetooth control boat When power On this boat, the Bluetooth module starts the data communication process. That is, data is communicated between the Bluetooth control app and the Bluetooth module. After, this data is sent to the Arduino UNO board through the Serial communication method. Then, the motors rotate according to that data. All these are done through the Arduino program.

OK, let's do this Bluetooth-controlled boat project.

You'll need: an

Arduino UNO,

HC-05 Bluetooth module,

L298N motor driver,

two gear motors,

two robot wheels,

one caster wheel,

two Li-ion batteries,

a Li-ion battery holder,

jumper wires, rigid foam,

and popsicle sticks.
