LED Wiring
The LED strip has three inputs: +5V, Gnd, and data input. The data input has to come from one end of the strip, indicated by the arrows. The power for the strip can come from any end. The +5V needs…
Capacitive Touch Sensors in a Grid
It is also possible to take the idea discussed in Why Keyboards Matter post and tailor it for capacitive touch. This way it also possible to represent 900 individual user inputs with far less microcontroller pins. The main idea behind this…
Peabody Overall Report
Peabody project involves making a physical version of Peabody’ alternative timeline representation. The main components will include 30 NeoPixel strips, Arduino Mega microcontroller, and some kind of touch sensors. The project can be subdivided into four parts: crafting the actual…
