Microcontroller PIC 18F8720 microcontroller in an 80-pin TQFP package. A small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. designed for embedded applications (remote controls , appliances, power tools…) Interrupts - real time response to events in the embedded system. שליש או רבע מהזמן Two ATMega microcontrollers   PIC 18F8720 microcontroller in an 80-pin TQFP package.

Microcontroller Today – 32bit Microcontrollers as cheap as 1$ 1971 - Gary Boone and Michael Cochran succeeded in creating the first microcontroller, TMS1000. Contained: ROM, R/W memory, processor and clock on single chip 1976 - Intel develops Intel 8048 with massive success 1993 – EEPROM introduced (Replacing EPROM & PROM) & Atmel introduces first microcontroller with flash memory Today – 32bit Microcontrollers as cheap as 1$ שליש או רבע מהזמן Intel 1702A EPROM

Single-board microcontroller A microcontroller built onto a single printed circuit board (PCB)  Provides all necessary HW:  microprocessor, I/O circuits, clock generator, RAM Cheap, especially for development Emphasis on IO (digital/analog) Real time programming & embedded programming – response to signal/interrupts opposed to traditional embedded The Make Controller Kit with an Atmel AT91SAM7X256 (ARM) microcontroller.

Example (if there’s time…) Bread board

Ex1 PWM – Pulse width modulation Light a led using PWM and video it – you will experience aliasing. Use the Aliasing to flash your ID & record it. Have something to indicate time units Be creative! Submission- Email to Amit on behalf of team containing ID’s and a video with your solution.
