sir can you give me the programming of 12 channel temperature scanner i can't understand what to do.. plz help me... thanks mital
The best recommendation is that you talk with your teacher.
You may already have received information about what sensors to use. 12 analog sensors to a multiplexed ADC. Or 12 I2C or Dallas one-wire sensors. Or maybe 12 pulse-length-encoding sensors.
The type of sensor will decide the next required steps.
But the first three steps: Read datasheet for temp sensor(s). Read datasheet for processor. Once more read project description.
