Sometimes, we use depth-measuring machines to measure the quantity of a beverage or mixtures of liquid materials poured into a glass. The fundamental variable that needs to be known for these machines to measure depth is the depth amount measured when the container is empty. After defining this information to the measurement devices, the device performs the measurement process by using various sensors such as ultrasonic distance sensor, IR sensor, etc.

In this project, we will control the water pump connected to the motor driver based on the value measured by the ultrasonic distance sensor we connect to PicoBricks. We will transfer the desired amount of liquid from the container filled with liquid to the empty one. To determine the depth of the glass, we will use the potentiometer & button module.
