I'm thinking to buy a Nano 3 IoT together with the DS18B20 temp sensor and a Humidity sensor so I can monitor my Vivarium continiously. This all works fine with my Mega 2560 but as I read that the max voltage for the Nano 33 is 3.3V for the digital and analoge ssignals I was wondering if this goes fine?
The signal wire from the sensor to pin4 (pwm) is connected with a pullup resistor connected to the 5Vdc.
Anybody has exerience with this Nano and sensor combined?
Thanks in advance
