Rotating display with light for miniatures/jewelry

thingiverse

This is a very small rotating display case with Neopixel lamp post. The diameter of the rotating plate is 43 mm. The rotational movement is random within 180 degrees servo limits. The lamp utilizes one LED from a Neopixel strip. The light is normally quite close to white with occasional periods of more saturation to rainbow colors. https://www.youtube.com/watch?v=uQkgh-B6lkY In addition to the printed parts, the following components:are needed: Arduino Nano SG90 micro servo one LED from a Neopixel strip pushbutton switch 1010 type The pushbutton switch is used to toggle servo motion on/off. It is not necessary. By default, the servo is on, but it can be changed in the sketch by changing servoOn = true to servoOn = false. *Note:* Use ServoLimits sketch in the Arduino IDE examples to figure out the real limits of the servo you are using. By default, min and max limits for the servo are 1000 and 2000, but I had to change them to 550 and 2400 for my servo! Attach the servo with screws, and the button switch and Arduino with double-sided tape. *Connections* The components are connected to the Arduino as follows: Neopixel data in to D4 (also +5V and Ground) Servo data to D9 (also +5V and Ground) Button switch between D2 and Ground The system can be powered via the USB connection of Arduino Nano.
