Butterfly CPX

We made a butterfly that is on top of a lit up CPX board. The purpose of this is to spin and flash different patterns of light.

-CPX 3-D printed base/holder

-3-D printed butterfly

-servo motor

-cpx board with wire to connect to computer

-battery

-wires

Print 3-D butterfly and CPX holders.

Create the code to allow the CPX board to light up with specific patterns and functions. Use python for this step.

        cp.play_tone(1000, .5)

        time.sleep(.5)

        my_servo.throttle = -1.0

        time.sleep(.5)

    else:

        my_servo.throttle = 0.0

Glue the servo motor to the bottom of the CPX holder. Solder the red wire to VOUT and A2 to orange. Then attach brown to the ground.

Attach the wings to the body of the butterfly. Then, attach the whole butterfly onto the top of the CPX board.
