Medical & health related projects & systems.

Power supply and charger based applications.

Solar powered machinery and applications.

Industrial machinery controlling systems.

Some of the applications for the chip are as follow. Every day we see a new application built using the this chip by electronic students, engineers, hobbyists, tinkerers. There are thousands of applications for Atmega328P also more to come in near future depends on how creative one can think. The EEPROM and the flash memory are the memories which saves information and that information still exits every the power is disconnected or off but the SRAM is a memory which only saves the information until the power is supplied and when the power is disconnected all the information saved in SRAM will be erased. The chip contains 32 kilobytes of internal flash memory, 1 kilobytes of EEPROM and 2 kilobytes of SRAM. The internal circuitry of ATmega328P is designed with low current consumption features. It is a microcontroller from the Atmel’s megaMVR microcontrollers family (Later in 2016 the Atmel is obtained by Microchip Technology Inc, the microcontrollers manufactured in megaMVR family are designed for handling larger program memories and each microcontroller in this family contains different amount of ROM, RAM, I/O pins and other features and also they are manufactured in different output pins which are from 8 pins to hundreds of pins. It is one of a famous microcontroller of Atmel because of its use in arduino UNO board. This pin also used as serial interface clock line.ĪTmega328P is a very advance and feature rich microcontroller. This pin can also be used as serial interface connection for data.Īnalog input digital value channel 5. This pin is act as a master clock output and slave clock input for SPI.Īnalog Reference voltage for ADC (Analog to Digital Converter)Īnalog input digital value channel 4. This pin is act as a master clock input and slave clock output. This pin is used as a master data output and slave data input for SPI. Pin 11 is used for external counter source Timer1 This pin should also be connected to another pin of the crystal oscillator to provide external clock pulse to the chip This pin should be connected to one pin of the crystal oscillator to provide external clock pulse to the chip Pin 6 is used for external counter source Timer0 When this reset pin goes low the microcontroller & its program gets reset.
