Hi,
Hi again everyone. I want to connect a thermistor to the ADC port of a PICAXE 28X-1. But on looking at the 'Interfacing Circuits' data sheet i discovered that you have to add a resistor after the thermistor and connect it to 0V. I am fine with doing this but was just wondering what it was for and if the value of the resistor mattered. If you don't know what i mean then a diagram is located on the interfacing circuits datasheet and is on page 29.
Thanks,
Daniel
