In this instructable I am going to show you how to make Bluetooth controled car with 2 DC motors.
Step 1: Materials
1.2x DC motor
2.L298N (motor controler)
3.Arduino Uno (or clone)
4.HC-05 (bluetooth module)
Step 2: Chassis Editing
I cut off Middle plastic part and replaced it with wood, then I added 4x1.5V battery pack in the middle of it.
Step 3: Wiring Scheme
Connect one motor to the OUT1 and OUT2 pins of L298N, connect second to the OUT3 and OUT4 pins.
Connect positive wire of batteries to +12V pin and negative to the GND of L298N, then connect same GND to GND of arduino.
Pins of HC-05 are conected to arduino like this: GND to GND; VCC to 5V; RX to TX and TX to RX.
Pins of arduino 8,9,10,11 are connected to IN1,IN2,IN3,IN4 of L298N.
Step 4: Connecting
Connect wites like in prevous step.
Step 5: Upload Code to Arduino
Connect your PC to Arduino and upload this code.
Step 6: Download App
You can download app here:
Step 7: App
Open app, turn bluetooth on and connect it to the HC-05.
Step 8: Done
