I am considering simulation of temperature returns to a picaxe from multiple DS18B20s with the temperature set by PWMing through a resistor potted to the top of the DS18B20.
The module, with 6 or more DS18B20s would be placed in a freezer, so I could, in theory, get temperatures from -18C to 35C.
With good thermal isolation between the DS18B20s, what sort of R would I need when running off of 4 or 6 or 8 AA batteries?
With a 20M2 can I get 6 PWMs with the same rate (say 1kHz) but different duty cycles?
