MICROP LESSON3

Microprocessor

Heart of a computer system, is an IC which has only the CPU inside them i.e., microprocessor find applications where tasks are unspecific like developing software games,website

Microcontroller

Heart of embedded system, has fixed amount of ram rom and other peripherals all embedded on a single chip, mini-computer

MicroChip,Atmel,intel,analog devices and more

Famous microcontroller manufacturers

Arduino

is a prototype platform (open source) based on easy to use hardware and software, was introduce in 2005 in italy, under creative common license which allows anyone to produce their own board

circuit board

can be programmed

Arduino IDE

used to write and upload the computer code to the physical board

Massimo Banzi

introduced the arduino

Arduino Uno R3

is a microcontroller board based on the ATmega328 microcontroller chip

Lilypad arduino

the lilypad arduino is designed for e-textiles and wearable projects

Arduino mega r3

based on the ATmega1280

Arduino leonardo

first development board to use one microcontroller with built in usb

Arduino nano

is small and complete and breadboard friendly board based on Atmega328

Arduino Micro

the smallest board of the family easy to integrate in everyday objects is based on the ATmega32u4

Arduino Mini

is very compact version of the nano without an on-board usb to seiral connection

Arduino Platform

Physical/output board with a programmable integrated cirucit

C programming

language it based on

Sensors ( to sense stuff )

-            Push buttons, touch pads, tilt switches.

-            Variable resistors (e.g. volume knob / sliders)

-            Photo resistors (sensing light levels)

-            Thermistors (temperature)

-            Ultrasound (proximity range finder)

Actuators ( to do stuff )

-            Lights, LED’s

-            Motors

-            Speakers

-            Displays (LCD)

USB Plug

can be the source of power, use to upload the program from the computer

External power port

Alternative power port for the source of power

Ground pins

use as ground in your circuit

5v Pin

supplies 5v source

3.3v pin

supplies 3.3v source

Analog input pins

Label from A0 to A5 used to read signal from analog sensor

Digital I/O inputs

Label is from 0-13 used for digital input for pb or outputs for leds

Pulse-Width modulation Pins PWM

act as part of no1, used to simulate analog output

Analog reference pin

Used to set an external reference voltage but most of the time you can leave this pin alone

Reset button

-            Restarts any code loaded in ARDUINO

It is very useful if your code is not repeating, but you want to test it multiple times

Power led indicator

led indicates that the device is connected to supply of a computer

TX RX LEDs

tx means transmit and RX means receive

ATmega Microcontrolle

Serves as the brain of arduino

Voltage regulator

Controls the amount of voltage is let into the board

Verify

compiles and approves your code

Upload

sends your code to the board

New

open new code window tab

open

open up existing sketch

save

saves the current active sketch

serial monitor

open up a window that displays any information your board is transmitting very useful for debugging

sketch name

it shows the name of the sketch you are currently working on

Code area

it is the area where you compose the code for your sketch

Message area

it is where the IDE tells you if there is any errort

text console

shows complete error message, when debugging the text console is useful

Board and serial port

it shows what board and the serial port selections
