Write an arduino code in order to make this car work:

$-$ P$1.$ The car shall travel forward when there are no obstacles within $\backslash (\backslash$sim $\backslash$beta $\backslash )$ feet of its forward$-$travel direction.

$-$ P$2.$ The car shall display one or more glowing green LEDs when it is traveling forward and there are no obstacles within $\backslash (\backslash$sim $3\backslash )$ feet of its forward$-$travel direction.

$-$ P$3.$ The car shall execute an avoidance maneuver so as to avoid collisions with obstacles within $\backslash (\backslash$sim $3\backslash )\text{'}$ of its forward path.

$-$ P$4.$ The car shall light up a red "obstacle$-$detect" LED when obstacles $($including walls, people, other cars$)$ are detected within $\backslash (\backslash$sim $3\backslash )\text{'}$ of its forward$-$travel direction and the car is executing a collision$-$ avoidance maneuver.

$-$ P$5.$ The car shall be demonstrated according to the following plan: you will apply battery power to your car, and set it moving forward, heading toward an obstacle $($such as a person, a wall, or another car$)$ placed $\backslash (>6\backslash )\text{'}$ away. A green forward motion indicator LED will be demonstrated. When the distance decreases to $\backslash (\backslash$sim $3\backslash )$ the car shall detect the presence of the nearby obstacle, light up a red obstacle$-$detect LED and perform a collision$-$avoidance maneuver. After performing the maneuver, the car will turn off the obstacle$-$detect LED and resume forward motion in another direction. You need to demonstrate a minimum of $4$ collision$-$avoiding maneuvers during the required demo.
