In this tutorial we will set up and read the temperature from LM35 using ADC of Atmega32 AVR breakout.
Basics
Initially we will read a raw data from ADC. Atmega32 comes with 10-bit 8-channel inbuilt ADC. We will connect 10k Pot to channel 0, vary it and read the raw voltage. After that we will connect the LM35 temperature sensor to channel 0 and read the temperature as shown in hook up. We will display the converted value on terminal.
Refer Reading Temperature with AVR ADC for basics of Atmega32 ADC and LM35 temperature sensor.
