Building Array
1. Hot glue servos to board
2. Center Servos and attach an arm
3. Hot glue another servo on top
4. Attach servo wires to PCA9685 board, watch orientation of plug and start with the side with servo 0
5. Attach i2c lines, GND and 5V to Arduino
6. Find external 5V source, and use screw terminal
7. Be sure and attach Arduino and external 5V source ground together
8. Route and tape down servo wires so they will reach end and yank on the cable, and also not to catch on anything.
9. Attach the Laser Diode power and grounds (use external 5V source)
10. Install Adafruit Servo Library. Start with example code and add features and test.
