Is ATmega32 and atmega328 same?

They only differ on the hardware features and can be programmed in more or less the same way. It is up to you to choose which one you want to use. The only nearly identical ones are 328 and 328P.

What is the difference between ATmega16 and ATmega32?

ATmega32 is very much similar to ATmega16 microcontroller with certain differences which are discussed below. ATmega32 is an 8-bit high performance microcontroller of Atmel’s Mega AVR family. Atmega32 is based on RISC (Reduced Instruction Set Computing) architecture with 131 powerful instructions.

What is AVCC pin?

AVCC is the supply voltage pin for the A/D Converter, Port C (3.. 0), and ADC (7.. 6). It should be externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC through a low-pass filter.
