P.Com Midterm and Final Project Proposal

For our P.Com midterm my partner, Gladys Chan and I created an RGB Color Mixing game. The game consisted of a specialy made controller comprising of 3 Force Sensing Resistor pads for each player. Each pad corresponded to an RGB value and the goal of the game was to mix colors an attempt to match a target color displayed on the screen.

In revision two the goal is to refine the UX. There were many complications in revision one we wish to improve. by redoing the mapping algorithms that control the FSR sensors we will make it easier for uses to hold values, we will also me instituting rubberization techniques into the physical component to further ease the ability to hold values. The UX will have a minor overhaul, creating clear goals for both players. We hope to have this running in the web browser and eventually have it running on an iOS tablet. Therefor we must convert the controllerto bluetooth LE.

Physical Bill of Materials:


– Wooden enclosure (container store)

– Acrylic top (custom cut)


– LightBlue bean – Bluetooth LE

– Multiplexer ( add extra analog input)

– Breadboard

– 3 FSRs

– 3x LED (RGB) // dim as fsr is pushed

– Button/switch – to turn on and off

– Molded rubber for buttons
Clip wires to connect FSR to board for easy replacement

    You don’t necessarily need Bluetooth LE. There is a a nice BluetoothSerial plugin for PhoneGap/Cordova that works fine as a plain old Bluetooth 2.0 serial port. See https://github.com/don/BluetoothSerial

    Hey Tom, Thanks for this advice, the Bluetooth LE/multiplexing has been getting fairly complex! I think I will be switching to the traditional bluetooth serial for the final.
