obstacle avoiding car >> this car stop when it found a wall or any obstacle ,,the output of it is an anglar velocity ,,my question is  "how we use this anglar velocity  feedback for motor and pid controller or the feedback be 1

this project without arduino

I don't know how to make this without an Arduino. the ultrasonic sensor output are pulses and you need to count the time between the pulses in order o detect the distance. Without a microcontroller with a timer, I don't know how you could measure time...
