Provide codes and tinkercad simulation

Steps for Tinkercad Simulation Setup :

And so$,$ position the Arduino Uno on the datasheet of the virtual work space.

Let the pushbuttons be connected to the digital pins for illustration, pushbuttons $2,3$ and $4$ respectively to be connected with pull$-$down resistor.

Attach LEDs to digital pins $($e$.$g$.,8,9,10)$ through $220$ resistors.

Set up the limit switches to digital pins $($e$.$g$.,5,6,7).$

Connect the DC motor to the L$298$N motor driver:

Attach the motor to the output terminals of the driver.

Solder the input leads such as IN$1$ and IN$2$ to electric pins on the L$298$N to Arduino such as electric pin $11$ and $12.$

Tie the L$298$N power and ground pins as required.They are the pins passing with high current carrying capacity through two rows from IN$1$ and IN$2$ to OUT$1$ and OUT$2.$

To control motor, connect the motor driver with a $12$ V external power supply $.$

Make sure that the Arduino, motor driver and other components have a common ground.
