Advance Microcontroller AVR
- Microcontrollers are small computers contained on a single chip that contain a processor core, memory, and input/output interfaces. They are used in automatically controlled embedded systems. - The AVR is a family of microcontrollers developed by Atmel in the 1990s. It uses RISC architecture and is commonly used in hobbyist and commercial projects due to its low cost and availability. - Code is burned onto AVR microcontrollers using a software program called Atmel Studio, which allows writing code in C or assembly language. The program is then loaded onto the microcontroller through its pins.

- 4. Microcontrollers A microcontroller(sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.
- 5. Microcontroller Basics CPU–CPU is the device which is employed to fetch data, decode it and at the end complete the assigned task successfully. Memory –Memory chip stores all programs & data. Input/output ports – I/O ports are basically employed to interface or drive different appliances such as- printers, LCD’s, LED’s, etc
- 6. Microcontroller Basics ADC(Analog to digital converter) – ADC is employed to convert analog signals to digital ones. DAC (digital to analog converter) – this converter executes opposite functions that ADC perform. This device is generally employed to supervise analog appliances like- DC motors, etc. Serial Ports – These ports give serial interfaces amid microcontroller & various other peripherals such as parallel port. Timers – A microcontroller may be in-built with one or more timer or counters

Need of microcontroller periodically read the temperature (analog value, is digitized by sensor; uses 4-bit interface), control heating according to the temperature (turn heater on/off; 1 bit), display the current temperature on a simple 3-digit numeric display (8+3 bits), allow the user to adjust temperature thresholds (buttons; 4 bits), and be able to configure/upgrade the system over a serial interface.
- 12. History of Microcontrollers The first microprocessor was the 4-bit Intel 4004 released in 1971, with the Intel 8008. The Smithsonian Institution says TI engineers Gary Boone and Michael Cochran succeeded in creating the first microcontroller in 1971. The result of their work was the TMS 1000, which became commercially available in 1974.
- 13. Advance Microcontroller AVR AVR was developed in the year 1996 by Atmel Corporation. The architecture of AVR was developed by Alf- Egil Bogen and Vegard Wollan. AVR derives its name from its developers and stands for Alf-Egil Bogen Vegard Wollan RISC microcontroller, also known as Advanced Virtual RISC. The AT90S8515 was the first microcontroller which was based on AVR architecture however the first microcontroller to hit the commercial market was AT90S1200 in the year 1997.
