Create a code on Arduino IDE using Arduino Uno WiFi Rev $2,$ L$298$N$,$ MPU$6050$ and HC$-$SR$04.$

Arduino Uno WiFi rev $2$ will be connected to L$298$N which will control four $12$V motors. One HC$-$SR$04$ will be placed in front of toy car and will detect obstacles. Using HC$-$SR$04,$ the distance needs to be calculated so the toy car can brake automatically and safely.

MPU$6050$ will be connected to arduino uno WiFi rev $2$ as well. They will be placed on the base of the toy car. Gyroscope on MPU$6050$ will detect when there is incline will accelerate with push assist automatically when going uphill. The speed will slow down automatically when the toy car is going on a decline. It will travel down safely until it reaches a level surface.
