An Unordinary Keyboard

In construction

This page is still being written.

I wanted to make a set of quiz buttons for quiz nights and other events. It is a set or four buttons connected to one central hub, which can mimic a keyboard when attached to a computer. The buttons send signals for alphanumerical buttons 1, 2, 3, and 4 when pressed. When a button is pressed, it will light up for 5 seconds and prevent other buttons for activating during that time.

Materials

PCB

• FR4 PCB board
• Arduino Micro
• 100 &Ω resistor
• 4 TRRS audio sockets (PJ320E)

Buttons

• ULN2003A darlington array transistor
• Button with lights
• “Super bright” LEDs

Weeks when I Worked on this Project

• Restarting the Project Making the domes. Programming
• Making the PCB Logic and PCBs PCB

Button Boxes

These boxes were made during a separate woodworking class using a lathe and a drill. Their sturdiness and the cupola shape makes them a bit tricky to do with any of the digital manufacturing methods that are taught in Fab Academy.

The boxes were made to house the button, a light and the TRRS female connector.

Lights

Light bulbs to LEDs.
