We wanted to build a hardware hack with materials we had on hand. Our goal was to build a arcade style game that is easy to learn but hard to master. This resulted in a RGB LED color strip race game assembled and coded entirely at the hackathon.
What it does
The goal is to clear the run as fast as possible. To advance the run, press the button that matches the first LED on the rainbow strip. Be careful! An incorrect color will set you back in the run! When you reach the end of the run, check your time, if the clock is blinking you have set a new High Score. Try all 4 levels to set your best times!
How We built it
Internally the game runs on an Arduino Mega, coded in ArduinoC. We control the clock display and LED strip via digital buses on the Arduino. The buttons are interfaced directly with digital logic so that we can use hardware interrupts for accurate game play.
Our enclosure is a prototype we built out of foam core board for the hackathon. We have plans to take it apart and laser cut each piece out of acrylic for a finished product.
Challenges we ran into
We encountered issues with buttons registering twice during the game. We thought it was a debouncing issue with our interrupts but an oscilloscope proved that the issue was more complex. We spent several hours diagnosing this issue and determined that the hardware interrupt configuration was to blame.
Accomplishments that we are proud of
For our team of 2, this is a first for: Joe - His first hardware hack Lucas - His first submitted hack ever
What we learned
Projects can take longer than expected, but watching them come to life is worth the effort.
