Hi, i am working on a button controlled car. It has 4 push buttons for direciton and 1 button for start. I want the user to create a route using 4(forward, backward, right, left) buttons and then press the start button to move the car on the specified route. I am using an arduio uno, L293B motor driver and 2 dc motors. Here is my code.
`//MOTOR PINS
int ena = 6; //alt motor
int in1 = 7;
int in2 = 5;
int in3 = 2; //üst motor
int in4 = 4;
int enb = 3;
int ileri = 8;
int geri = 9;
int sag = 10;
int sol = 11;
int basla = 12;
//#define ileri_pin false
//#define geri_pin false
//#define sag_pin false
//#define sol_pin false
//#define basla_pin false
int i = 0;
int hareketler[30] = {};
int uzunluk = 30;
bool basladimi = false;

I am new to programming but i don' think there is problem with my code because i checked the value of the variables in the code depending on the state of the buttons
The problem is that the motors are not working. I know there could be many reasons for this. Do you have any idea how can i solve it?
