My selected idea is a circuit takes the first input from a button as ON/OFF to open a box using the servo motor horn as the first output. When box is opened the buzzer play a sound as the second output. I have a potentiometer as the second input to enter a variable time period can be a delay period to open the box.
I try to implement an idea inspired from my final project idea to build a box open with a timer and here we can set the time using the potentiometer.

Design/Preparation Process
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?

- The circuit has 2 action component (1 Buzzer) && (1 servo motor).
- The circuit has 1 input component (1 potentiometer) && ( 1 button).
- The breadboard will connect components with Arduino.
- The circuit scenario.
* When pressing button ON the servo will move to 45 to close the box.
* The potentiometer will feed the circuit by a variable value as the variable timer period .
* When pressing button OFF the servo will move to 130 to open the box after period identified by potentiometer and play a sound on buzzer to mention the box is opened.

- Firstly I included <servo> library to get ability of working on servo capabilities.
- I firstly also declare a constant with initial value identify the delay value with 0.
- The setup part contains my declaration for used components to use it with Arduino for both input and output.
- The logic part is simple. Firstly I read value from push-button to move servo to 45 degree and close the door at same time to mute the buzzer.
- Secondly If I want to open the closed door:
* I get the passed time since Arduino started and store in a variable.
* I built a comparison condition to compare difference between Arduino passed time and time to begin timer regard to the time I set as a timer time through potentiometer move ( 30000-60000).
* IF the condition had been met it will move servo to 130 degree and is the door will open, and same time play a sound from buzzer.
- Making wiring for servo motor with both breadboard and Arduino.
- Writing code to test motor movement and identify the suitable horn positions in open and close status.
- Adding buzzer and making wiring for it with servo motor
- Adding code to play a sound on buzzer with servo positions in both close and open.
- The buzzer sound will be while the box is opened and will be muted if the box is closed.
- Adding potentiometer and making wiring for it with servo motor and buzzer.
- Adding code to map potentiometer analog value into values can be used as a timer interval for close the box.
- Testing the whole code to ensure working well and do functions as plan.

Some of points within videos were not clear and I have to use a written tutorial as it is better for me to read more than watching videos.
I did not receive expected values from circuit specially when moving potentiometer to change the value that will be mapped into timer period. I tried tracing the code many times without solving the problem. But when tracing the wiring I noted that I am using GND bin instead of input bin as they are adjustable and the bins are very close. Next times I tried to make sure that wiring is in correct bins.

Every time before begin making process like in assignment, I feel anxiety and I can not do it and I still need a lot of study. But after two or three minutes from beginning alone or with a team I feel better and it was not as bad as I thought at beginning.
