I made a 3d sonar
I used two servos and ultrasonic sensor. Ngl its kinda bad for the reasons ill get into. Sound is bouncing off the barriers and the measures are a mess. Also it has a precision of +-1cm which means it cant really measure distances super precisely. But it is what it is. I didnt want to buy a lidar. If i ever do buy it ill redo this project. I might post code if anyones interested.
