Week #8 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

arduino controlled servo door lock

I was inspired from this idea, a way to lock and unlock your door through your smart phone

link: https://www.hackster.io/raghavdaboss/arduino-controlled-servo-door-lock-1c2239

i thought of making a full control of the door (to open it till 180 degree and close it).. i also thought about controlling buzzer to work and stop through the smart phone

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

I built a simple smart circuit on breadboard that contains a TWO action components that i can control wirelessly
I used servo motor, jumper wires, breadboard, buzzer, arduino uno, USB cable and bluetooth module.

I used arduino ide software to write code and upload it on arduino and tested my circuit to make sure it's working first using serial monitor

I used Arduino Bluetooth Control (GUI) to control the action components and display calculated distance values of US sensor

I used fritzing to make wiring diagram needed

software/machines/materials needed

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

my project

Code

At the beginning, I used my breadboard and electrical components to build my circui

1-first, i made 2 lines on small breadboard on the corners one for positive and other for ground and connected them to 5v and gnd of arduino.

2- second, i connected the buzzer (first action component) short terminal to ground of breadboard, long terminal to digital pin 2 on arduino

3- third, i connected the servo motor (second action component),it has 3 terminals, i connected red wire to positive on breadboard ,brown wire to ground in breadboard, and orange wire to pin 9 on arduino

4- At last, i connected bluetooth module, it has 4 terminals, vcc to positive in breadboard, gnd to gnd in breadboard, rx to tx in arduino and tx to rx in arduino (pins 1,2)

second, i started coding my project on arduino IDE, i coded it that if the data coming is "1 " the servo will rotate clock wise from 0 to 180 degree (by adding 10 degrees each time) and if the incoming data is "2" the servo will rotate anti clock wise from 180 to 0 degree (by subtracting 10 degrees each time)... if incoming data is "3" the buzzer will work and if it's "4" the buzzer will stop

first i displayed values on serial monitor so i removed bluetooth module

Then I connected the bluetooth module, connected it to my mobile's bluetooth, used Arduino Bluetooth Control app to remotely control the buzzer and servo by pressing on buttons from 1 to 4

At last, I used fritzy to make wiring diagram needed

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

I made the code that if the data coming is "1 " the servo will rotate clock wise from 0 to 180 degree (by adding 10 degrees each time) and if the incoming data is "2" the servo will rotate anti clock wise from 180 to 0 degree (by subtracting 10 degrees each time)... if incoming data is "3" the buzzer will work and if it's "4" the buzzer will stop

first i displayed values on serial monitor so i removed bluetooth module and it was working

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

yes, i have iphone, so i couldn't find mobile app to make my assignment... so i borrowed an android mobile from my colleague to complete the assignment

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

i got stuck at 2 points

first, when trying the led with bluetooth module code on serial monitor (tutorial video) , i had an error, so i sent this video to my instructor yassin, he told me to unblug bluetooth module, then upload the code, the plug the blue tooth module, and it worked

second, uploading the code on iphone bluetooth mobile app. i downloaded several apps and no one could read the bluetooth module
so i asked on communoty troubleshooting on slack and i knew from Mr. abdelrahman that it won't work on iphone
so i borrowed an android mobile from my colleagues to complete the task

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

I can use the bluetooth module to control the servo motor (control amount of candies the child can take) by smart phone

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

I attended an extra session with our instructor mohanad about 3D scanning.. it was so cool 😀

We used the kinect 360 to 3D scan ourselves

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

I adopted a persian cat, his name is SOKAR 😍
