Week 8 - Journal

Nobody move!

This week our assignment is to build and program a smart circuit using an Arduino UNO & control it using Bluetooth module and programming it using Arduino C code.

My inspiration came from a smart alarm system that used to secure a house.

Code Braking Down

I start by install and including the libraries needed for the LCD Screen, then defined the pins numbers and some variables that I'm gone need during writing my code.

Then I start by creating some functions that would make my life easy as It would reduce the line of code by write the function code once and re-use it every time I need it instead of writing it all over again when I need the same part of code.

setup() : It start by initialize communication between the Arduino and the LCD screen, then set pin mode and set the serial communication speed and print some text on the LCD Screen.

loop(): It start by while loop that as long as it's condition true it keep working until the condition is become false then read form the serial port and assign it value to a variable then a bunch of if conditions everyone of it check for specific condition and based on the condition it execute a part of code related to that condition.
