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)

This week's assignment is about building and programming a smart circuit using an Arduino UNO which reads a signal from an input component to control an action component using code blocks on TincerCAD.
I chose (Jolly Chimp monkey)

I designed my Jolly Chimp monkey to use the ultrasonic sensor to measure the distance between the monkey and the object and take an action depending on this distance.

The action will be a FATAL NOISEEEE

Tool Chain

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

Software

Tinker CAD
Tinkercad is a free software for 3D design, electronics, and coding,
I used it to design and simulate my circuit.

Components

Arduino Uno

Buzzer

Ultrasonic Sensor

Breadboard

Connecting Wires

5v Adaptor

Tools

Glue gun

scissor

sellotape

Material

Cardboard for the enclosure

Long screw

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?

Circuit Design On TinkerCAD

  1. First, I used an Arduino Uno board to control my circuit.

  2. I used an Ultrasonic sensor to detect the objects at a distance of 10 cm.

  3. I put a buzzer to be an alert if any object enters the ultrasonic sensor range.

  4. The same thing with the servo motor, it will rotate with a stick to make noise.

Block Code on TinkerCAD

  1. Ultrasonic sensor was programmed as an INPUT.

  2. The Ultrasonic detection range is 10cm.

  3. Buzzer was programmed as an OUTPUT.

  4. Servo motor was programmed as an OUTPUT.

Circuit Simulation On TinkerCAD

When the ultrasonic sensor detects an object at a distance of less than 10 cm, the buzzer will peep and the servo motor will rotate to 90 degrees for 0.3 second and then return to 0.

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?

Prototyping On Breadboard

  • The positive terminal of the buzzer is connected with pin 13 in Arduino.

  • The negative one is connected with the common ground.

  • The red wire of the ŮŤservo motor is connected with the 5v pin in Arduino.

  • The black one is connected with the common ground.

  • The orange wire is connected with pin 7 in Arduino.

  • The Vcc terminal of the ultrasonic sensor is connected with the 5v pin in Arduino.

  • The GND is connected with the common ground.

  • The Echo pin is connected with pin 5 in Arduino.

  • The trigger pin is connected with pin 6 in Arduino.

Enclosure




  • Using Cardboard I was trying to make a monkey.

  • I mounted the ultrasonic sensor and buzzer to look like a monkey's mouth and eyes.

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

I had a problem understanding the map() function, but with the instructor's help, I understood it.

Here is a nice tutorial that explains the map function.

Final Project

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

  • Using Arduino to control my project.

  • Using Arduino IDE.

WOW!

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

Weekly Digest

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.
