Week 8 - Journal

Communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) on your phone or PC. 

I've got my inspiration from this project it will be coolest thing when you just click on your phone to raise and lower your roller curtain.

first i simulate simple circuits on Tinkercad one of them shown is that motor drive L293D then i wire it in reality and check it's running well.

second simple circuit is that RGB LED.

so i test it by Osama Ahmed code to run different colors on it after that i've added extra colors later.

// *Interfacing RGB LED with Arduino

// * Author: Osama Ahmed

then marge two simple circuits together and write code on Arduino IDE.

i put motor turn off and led turn on while there isn't any input sending from Android phone.

when user input send it will work depends on what user's sent :

here if user sends 1 it will turn motor up and led on RED color,

and  if user sends 2 it will turn motor down and led on green color.

measure the diameter of inner hollow,

then cut small cardboard with the same diameter

assemble them in enclosure was the challenge cause the project easily work on table but when i try to fix it in enclosure or in window, but the link between roller and shaft of motor has broken up many times.
