Array Storing multiple OneWire addresses with Teensy (Arduino)

Three DS2413 1-Wire breakout boards with ID captured into Arduino array

I am looking at using the OneWire (1-Wire) protocol to build a string of switches for Teensy (Arduino). The OneWire protocol is a communication Bus System that sends and receives data over a single wire. It is meant for low data rates, and so using it for addressable switches, when all I need is to know off or on, seems perfect. I looked at the DS2413 chip as it has two IO pins that can […]

I did this for many reasons, but primarily I was extremely dissatisfied with the locked down nature of the standard iphone/apple experience. I wanted control over the phone as an interface with my microelectronics projects. Android allows […]
