I am currently working on a project where I need to measure the resistance of a material with increasing temperature (35oC to 100oC). Presently, I am measuring the resistance using a Keithley 2002 multimeter and varying the temperature using a setup containing a voltage controller. The drawback of the current way of measuring is that I have to be present throughout the experiment and note down the corresponding resistance reading for each 5oC increase in temperature, which is quite hectic. So, I was thinking of developing an ohm meter using Arduino mega and interfacing a temperature sensor with it. Therefore, can anyone of you guys can help me building the code for measuring the resistance for every 5oC rise in temperature. And, also I need the output of the result in excel format.
Note: Using ADS1115 ADC, I have already build ohm meter which can accurately measure the resistance of the material.
