Steps
- Build a gantry with the linear rail and stepper motors above the water tank.
- Mount the waterproof ultrasonic sensor on the gantry facing down into the water.
- Program the Arduino to move the sensor in a grid and record distance at each point.
- Place objects in the tank and scan them.
- Process the distance data into a 2D image in Python or Excel.
- Compare the image to the real objects and document the rig for your portfolio.
What to photograph for your portfolio
