Week #6 - 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)

Security Alarm

The assignment idea is to design an electronic circuit with an input component.

I chose the Security Alarm as an idea for my circuit components.

TOOL CHAIN

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

Breadboard

Resistor 220 ohm (2)

Reflection IR Obstacle Infrared sensor

Buzzer

Arduino Uno

Jumper Wires

Adapter 5V-2A

Red Led

Painters Tape

Scissors

Butter Paper

Paint Marker

Cardboard

Scalpel

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?

Prototype the electronic circuit on a breadboard

In this project, I used one input (IR Infrared sensor) two outputs (RGB Led) for lights, and (Buzzer) for alarm sound.

Get the power supply (5v - 2A) as the power source, I used a Breadboard to be easy

in hiding at the bottom of the cardboard house.

I used two resistors 220 ohms for the 2 LEDs.

I chose the RGB LED to make a change in output shape by using two colors (red and blue) instead of just red color also to be familiar with how to code it in the circuit.

May you check the video simulation for the Circuit shown in the video below ↓

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?

PROGRAMMING

Programming:

(Using Code Blocks)

I chose (if...else) from the control panel as I use (input) and (output).

... ~ IF~ ...

For the input:

(IR Infrared sensor), I used (read digital pin) command and chose the IR digital pin where I put it in the Arduino and put the command in the math command (smaller or bigger than), then attached the low and high drop button.

For the output:

1st- The RGB LEDs from the output panel I chose (set pin ... to low /high) command to make it like the police care light " which means you got caught".

2nd- The Buzzer from the output panel I chose (set pin ... to ...) command to make it on a switch in the horn.

Also, I used the command (wait) in both (if and else) to make a melody in the tone and the light together to be like the original Alarm.

... ~ else ~ ...

I put all the commands low or down to make the (output) stop interactive when the (input) is out of move detection.

Programming:

(Using Arduino IDE)

When I finished the Code Blocks Schema, I got the code source as shown below ↓

Then past the code source in Arduino IDE, verify the process is correct, not red notices, That's Great!

Let's connect the Arduino Uno by the digital cable to Upload the code as shown below ↓

Get all the components attached to wires like the design in Tinker CAD, then test the circuits to make sure all goes right.

PROTOTYPING CARDBOARD

The Idea:

I wanted to make a vintage Bank Building like this ← photo but there wasn't nor time, or materials, unfortunately.

As the Prototype makes the purpose of the circuit clear, I tried to make something so simple.

21x17cm (5 pieces) for the sides and roof

Balcony for decoration

added some colors

Put a handle on the door

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?

Learning from Mistakes

When I started coding, all was fine in the Tinker CAD design and its' simulation, but then I tried it with hardware components. I noticed that the alarm was ringing without stopping. I checked all the components, all was good, I checked the code and changed some Value until I realized that we reflect the reading of the sensor from high to low in (if) and its reverse in (else).

Community of Learning

It was a great session to get together as a team again designed the circuit some fast, get it wired with Arduino Uno, and get the result fast and some touch of craft ... cool!

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?

Learning Arduino Map Function was hard at the beginning but when I focused all was good, I was just exhausted. When I came back home, I made it again it became familiar.

FINAL PROJECT

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

Slider preview

I can use the IR sensor on one side of the slider to make an automatic return.

WOW !

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

The Coolest thing I have learned this week was the map block in coding, which enables me to make the circuit in 2 modes (manual with (potentiometer) or automatic with (Ultrasonic sensor).

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.
