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)
In this week I learned how use Bluetooth module to control the actions of the components.
My assignment idea is a limited counter which count form 0 to 9 according to plus button "P" and minus button "M" and the buzzer is on when I press "M" and the number is 0 and when I press "P" and the number is 9.
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
I used tinkercad software, Arduino 1.8.15 and Arduino BlueControl App.
The materials which I used is Arduino, 7 segments, Resistors, buzzer, Bluetooth module breadboard and jumpers.
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?
1- I make the circuit in tinkercad and I used photoshop to put Bluetooth module with my circuit.
2- I used 2 action components (7 segments and buzzer), Arduino, Resistors (220 ohm connected with the 7 segment and 1K ohm and 2K ohm connected with Bluetooth module), buzzer, and jumpers. I made this circuit in real.
3- I made the code in steps:
Step1: I made the 7 segment count from 0 to 9
Step2: Connect buzzer and Bluetooth module
The concept of the code is:
I made x=0 to make the start number is 0. thin when I press "P" the action is (x=x+1) plus 1 above x to make it 1 then the light make number 1 and so on.
when I press "M" the action is (x=x-1) minus 1 from x.
When x=0 and I press "M" the buzzer on and print Error.
When x=9 and I press "P" the buzzer on and print Error.
Note: each no of x is contain a code to display the correct number in 7segment by high and low the correct pins.
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?
1- Pair my Bluetooth module on my mobile and open the app.
2- connect the Bluetooth module.
3- Go to settings to change Buttons input.
4- Change button A data to "P"
4- Change button B data to "M"
5- The app is ready to check the circuit

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?
My idea is like the hackathon idea.
My team in hackathon was Ramie and Esraa.
Esraa helped me to understand the hackathon connections and how to connect the Bluetooth module to the circuit.
Ramie helped me to understand the concept of the hackathon code.

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?
In the EOW session at the hackathon the Bluetooth is lost the connection more than one time and the solution was turn off the Bluetooth and thin turn it on again and repeat the connection again.
Lost connection.mp4In the first when I test the circuit the button plus is work but the minus not .
problem.mp4
Serial read is read only one time so it read plus but didn't read minus.
The solution is make the serial read is variable and put it in "char"
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
Now I know how to attach Bluetooth module in my final project.
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
The hackathon competition although we are lose because the connection was unstable but it was soo cool and fun
