L298N, HC-05 Simple Bluetooth remote car not running in Arduino Arduino board type used in this session is Arduino Uno R3 DIP/SMD CH340

Below is the description of wiring and code in Arduino to assemble a Bluetooth RC car using android smartphone:


Tested the motor dc result both of wheel works (can spin forward and or backward). power direct from the battery.
Tested HC-05 bluetooth moduled. The phone can paired the bluetooth module.
Tested out1 out2 out3 and out4 on L298N using direct power from the battery the wheel spinning (forward and or backward).
The code for the Bluetooth rc simple car used below as described.


The car failed to move (forward, backward, turn left/right). how to make the motor dc and or the motor stepper works remotely. thank you

sorry for my careless. finaly its works....wrong pin assign the main problem....should be IN1, IN2, IN4 and IN3 not IN1, IN2, IN3 and IN4. thank you for all hands for help before
