Dance Dance Revolution or DDR for short is a rhythm game that is played with a directional pad made for feet. Coordination and rhythm is tested by watching on screen dance notes making steps to the keys of the beat. It’s a simple step on up down left or right and sometimes even combinations of steps. DDR has been very popular in arcades and on game consoles. Now-a-days, however, the game can be enjoyed with a clone games like “Beats” for android, “Stepmania” for the desktop, or even FFR (flash flash revolution) online. This tutorial generally explains how to go about building a wireless game pad on the cheap to avoid buy expensive adapters or pads. Bluetooth control with Bluefruit EZ-Key honestly works so easily for that there is very little to explain about the controller beyond what is covered in the Bluefruit tutorial. No programing required! As opposed to using a HID emulating micro like the Arduino Leonardo which would require some small bits of code and a wire. Materials
A number of different materials could be used in this project for the dance pad component. Its all a trade off between reliability/quality, portability and cost. This tutorial prioritizes portability and cost. Using materials that might be found around the house or are affordable to get from the hardware store.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
