Step 2: Tank Build
You will need to assemble the following:
I used nuts and bolts to create a platform above this for the Arduino, Servo and PING.
I copied the dimensions of the Universal Plate set for the plexi glass second platform.
The laser pointer can be attached to the servo horn.
But what was really tricky for me, the Arduino Motor Shield uses up a ton of pins, but you cannot see it quickly as it is wired internally. I found it helpful to just quick sketch it out.
