Transcript of introduction to microcontrollers and the Arduino

An introduction to
microcontrollers uses history limitations how to use them why would you want
to use a microcontroller? cheap autonomous rugged robust examples of use low power small more examples 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. what? 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 went commercial in 1974 Cost has plummeted over time, with the cheapest 8-bit microcontrollers being available for under $0.25 in quantity (thousands) In 1993, the introduction of EEPROM memory allowed microcontrollers (beginning with the Microchip PIC16x84) to be electrically erased quickly allowing both rapid prototyping, and In System Programming. Intel developed a computer system on a chip optimized for control applications, the Intel 8048, with commercial parts first shipping in 1977. This chip would find its way into over one billion PC keyboards, and other numerous applications 1971 1977 1993 2009 common useful features I/O ADC Timers Interrupts Flash memory I2C/SPI UARTS Comparitors Watchdogs temperature
