i have always enjoyed using 1-wire devices because i like that i can use multiple digital sensors from the same data pin. this was another fun document to write. here are further instructions on how to use a 1-wire temperature sensors with the v2 controller. the v2 controller has inbuild interface circuitry for adapting 1-wire sensors as shown below. this makes it easy to use 1-wire sensors as there are 6 pins D26, 27, 28, 29, 30, 31 on the v2 controller dedicated (have switchable parasitic resistors) for this purpose
