Troubleshoot for ultrasonic sensor
In this week, I am deciding to make improvement for my prototype. For ultrasonic sensor i am deciding to make it sense obstacle at 18cm far. This value is a good value because when the sensor detect the obstacle in front of it, the controller can send data to motor driver to decide where to move next. so, the 18cm is a good distance to stop and avoid any collision of the prototype and the obstacle in front of it.
if the sensor detect more than 18cm than it is means the obstacle is far with the prototype.
