I want to read multiple DS1820 sensors using a Due. I have circuitry and sketch working happily on a Mega: but I wanted to check that it would be safe for my Due. Clearly, the data pullup needs to be to 3.3v rather than 5v. But there are several suggestions that the Vdd for the Onewire network coul…

DS18B20 Temperature Sensor - 5v supply, 3.3v data?
