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)

Sun tracking

Sun tracking project

The project can follow the sun and maximize the solar energy output by using a light detector resistor as a sensor, a servo motor as the output mode, and Arduino as a brain.

Tool Chain

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

I used Tinkercad to simulate the circuit

After that, I used the breadboard to see how the circuit worked.

LDR sensor kit , servo motor, breadboard, and Arduino are tools used.

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?

Design circuit in Tinkercad

Components:

Servo motor
Used PIR sensor instead of LDR sensor kit because no LDR in Tinkercad
Arduino uno

Steps:

Connect the servo motor to the Arduino
Connect LDR to the Arduino
Writing the code block

Screening from Tinkercad

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?

Connect LDR sensor to Arduino

Conncet servo motor to Arduino

Screening of the sun tracking project

Arduino code

// C++ code
#include <Servo.h>
Servo servo_9;
void setup()
{
pinMode(2, INPUT);
servo_9.attach(9, 500, 2500);
}
void loop()
{
if (digitalRead(2) == 1) {
servo_9.write(90);
} else {
servo_9.write(0);
}
delay(10); // Delay a little bit to improve simulation performance
}

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?

During this week, I worked with the team which made a great effort and we helped each other. We Build a Smart Waving Hand using Arduino.

The lantern combines two parts:

Manual work using the potentiometer.
Automatic mode using Ultrasonic sensor.

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?

When I got stuck, I asked Ahmed or Farida to help me.

Challenge

When I did my assignment, I faced a challenge connecting the servo motor and LDR sensor kit to Arduino. I forgot to connect the source 5V to the circuit. So after checking the connector, I saw this problem and finally connected the circuit to the source power 5V from Arduino.

We can avoid this problem when we do the assignment.

Final Project

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

Focusing on how to combine analog sensors and output motors are the skills and knowledge that I have acquired this week 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 coolest thing that I have learned this week is how to combine digital and analog input to actuator output.

Revision connections of the inputs and the outputs of the Arduino is the thing that I 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.
