Week 7# - 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 to build and program a smart device using an Arduino UNO that perform a certain function and read signals from multiple input components to control multiple action components using text code

I decided to implement part from my final project idea, and used a Potentiometer (input) to control Servo motor motion (output), and a LDR sensor (input) to control DC lamp (output).

Final Project Idea

Tool Chain

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

TinkerCad

I used Tinkercad to build and test the circuit connections and ensure everything was functional before installation.

Material used in Tinkercad

1 Breadboard

1 Arduino UNO

1 Servo motor

1 PIR sensor (Simulaties LDR Light Sensor)

1 Potentiometer

Materials for the device's enclosure

I used Cardboard, Glue gun, tape, cutter

Materials for electric circuit

1 Breadboard

1 Arduino UNO

1 Servo motor

1 LDR Sensor

Wires

1 potentiometer

9V adaptar

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?

I used Tinkercad to build and test the circuit connections, ensuring everything was functional.

I connected the 5V from the Arduino to the positive rail on the breadboard.

Connect the GND from the Arduino to the negative rail on the breadboard

connect the servo motor's ground to the Arduino's GND and its power to the positive rail on the breadboard, with the signal pin connected to Digital Pin 9.

For the PIR sensor, I used the same connections as the servo, with the signal pin connected to Digital Pin 2 on the Arduino.

Connect the potentiometer's ground to the breadboard's GND and its power to the positive rail on the breadboard, with the signal pin connected to Analog Pin A0.

Connections

For the code, I used text-based coding. I followed the 'baby steps' method, working incrementally to ensure each part functioned correctly.

At first, I tested each component separately and then added them together.

For the servo motor and potentiometer, I used the code from examples. (example-> servo -> knob) and it worked nicely.

For the LDR, I tested it using a serial monitor.

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?

Building the circuit

I recreated the Tinkercad circuit using hardware components.

*steps:

connect the 5V from the Arduino to the positive rail on the breadboard
connect the GND from the Arduino to the negative rail on the breadboard
connect the servo motor's ground to the Arduino's GND and its power to the positive rail on the breadboard, with the signal pin connected to Digital Pin 9.
For the LDR sensor, I used the same connections as the servo, with the signal pin connected to Digital Pin 2 on the Arduino.
Connect the potentiometer's ground to the breadboard's GND and its power to the positive rail on the breadboard, with the signal pin connected to Analog Pin A0.
For the Relay, I followed the connection shown in the pic

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)

LDR on breadboard

I wanted to mount the LDR module outside the enclosure so that it could easily detect light, but I didn't have enough crocodile wires to connect it, so I left the top of the device open to allow it to detect light easily.

Final Project

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

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.
