mdot Analog in: how to connect Grove temperature sensor?
Your Grove temperature sensor is made to be connected to an ADC input of your microprocessor.
Then you need to configure your microprocessor to use an ADC pin, and convert the voltage in input in a data by softawre.
So, pin described as "PB_1/AD0/DIO0" means that the same pin as three distinct function that can be used : PB number 1, ADC number 0, and Digital input/outpu number 0. But you can only use one function at a time by configuring it by software.
