Game Timer
Introducing the 3D Printed Family Game Timer, a simple and interactive tool that brings a new level of excitement to family game nights! This project is designed to make managing game time easier, helping players stay on track while having fun. This timer is powered by a Circuit Playground Express (CPX) and features easy-to-assemble 3D-printed parts and internals.
Perfect for all kinds of games, whether it's board games, card games, or quick challenges, this timer is versatile and customizable. You can adjust the colors by altering the code to match your favorite games and even personalize the design by 3D printing the parts yourself.
In this tutorial, we’ll guide you step-by-step through assembling our version of the timer.
Supplies
- Circuit Playground Express (CPX) - The microcontroller to power the timer.
- Motor - CPX compatible motor to control the CPX movement
- 3 Alligator Clips - For connecting the motor to the CPX
- Battery Pack - To power the CPX and motor.
- USB-C Cable - To load the program onto the CPX
- 3D Printed Base - To hold the CPX and internals
- 3D Printed Dome - Covers the CPX to avoid damaging sensitive components
- 3D Printed Legs- Supports the dome
- Hot Glue Gun with Hot Glue - To attach the Dome to the Base
Printing
Go into Tinkercad https://www.tinkercad.com/
- Upload each file and print them separately
- The Box
- The Dome
- Leg supports
Coding
- Using the files provided, download them onto your computer (Skip this step if the CPX is pre-loaded)
- Plug the CPX into your computer using a compatible USB-C cable
- Find the CPX in your files and drag the downloaded files onto the CPX
This code controls a (CPX) with a connected motor. When a loud sound is detected, the LEDs gradually transition from green to red, one at a time, pausing for 6 seconds between each step. After all LEDs turn red, a sound effect plays, followed by a sparkle animation on the LEDs. The motor then moves the CPX back and forth between 90° and 70°, simulating a shaking effect. Finally, the LEDs turn off, resetting the system.

Assembly
- place the motor into the blue base, leaving the wire poking out as shown
- slide the battery pack into the designated slot and connect it to the CPX
Assembly
Connect the male end of the alligator clips to the female end of the servo motor
Put the CPX on top of the motor
Attach each alligator clip to the CPX onto the following:
- V-out
- GND
- A2
Assembly
Glue the 4 support legs onto each corner of the base
Glue the dome onto the top of the support legs
