I have been having trouble with a part of a project i am undertaking. The project title is using a thermistor for temperature control. I have reached a stage in the project where i am confused.
I am using an 18X chip ( first time picaxe user also ) and the circuit consists of a potential divider which has a 5k thermistor and an Xohm resistor (havent decided what resistance this needs to be yet). I understand the ADC works in such a way that the 256 signals are split up to approximatly give 0.02 volt incriments. Now does this mean that when i hook the potential divider to the chip that it can only read 256 temperatures?
If this is not the case then a kick in the right direction would be much appreciated. Thankyou.
