Most industrial power supplies have a fine-tuning knob or dial, which allows the voltage to be set precisely, and the 5V supply was adjusted to less than one-percent error with no load. This may change once the LEDs draw power, but for now, it is suitable.
The H-bridge, which controlled the motors, was mounted to the side of the base near the top. First, the temporary Arduino Nano controller was removed after recording all the pin numbers and wire colors. The mounting hardware included four wood screws and four brass standoffs.
Not much care was taken to mount the device levelly, but this part will be hidden during operation so it should not be vital. IO wires to the controller were not secured.
Both power supplies were connected to the strip and turned on. The plug for the green 12V power supply was unpolarized, so care was taken to plug it in and maintain the hot and neutral connections. This may not make any difference to the supply.
12V wires terminated on the H-bridge. This was provided higher voltage and more available current than the 9V battery on top of not being likely to run out of power during a presentation.
