Sometimes, my work requires a soundtrack, because of this I didn't hear people approaching me as I'd be too focused to notice.  causing many awkward moments and one memorable left hook, (no worries I missed, and my co-worker laughed)  So I came up with the idea of a cube bell; visitors push a button and a group of LED's blink. Then I ran across a small version of the WOPR from "Wargames", and I had my case.  Video of LED's in action here: https://youtu.be/zWpbHMqR2c0  Instructions:  Print (note I ended up scaling the WOPR to 105 %)  , sand, paint -- I used acrylics. except for some parts that were metal on the original, then I used Testors  "Brushed Aluminum"   and or a silver paint pen. For the electronics you will need: Arduino Nano or Adafruit trinket or other Microcontroller that fits on 170 pin breadboard.    USB cable  7x 5mm LED's  6 RED 1 Amber  5x 330 ohm resistors  1 10k resistor  1 button, I used this one from Adafruit (https://www.adafruit.com/produ...) they are out of blue but have other colors avaible. 1 5x7 CM perfboard and a bit of scrap perfboard ribbon wire I got mine at Amazon (https://amzn.com/B007R9SQQM) header pins or dupont connectors  starter kit for dupont here (https://amzn.com/B012EOO9Q0) Code:
