Week 7 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What were you inspired by?

I got inspired by connecting multiple things together
DC motor speed Control using potentiometer with L298n - YouTube

Doppler Radar motion sensor RCWL-0516 + Arduino – SURTR TECHNOLOGY

Unfortunately this project I failed to do even how much I tried there is something wrong also I am concerned with time.

So I tried to stop poo and his friends from sneaking to kids rooms I will try to explain more.

In this week I discovered Arduino in a better way and I did code betters than using building blocks

The Idea behind the project is when The Light is off and Motion Detected a Buzzer + LED takes and Action

Tool Chain

Which software/machines/materials did you use this week? Why?

Arduino IDE software

Tried to use Fritzling I couldn't use it good within the time frame

Design Process

Explain the design process of your assignment. How did you use the tool/software to design and/or simulate your assignment?

Objectives
1. to make 2 inputs which are ( LDR sensor and Microwave Sensor)

2.to make 2 outputs which are buzzer and LED

Components:

1.RCWL-0516 sensor

2.LDR module

3.Buzzer

4.Breadboard

5.LED

Steps:

1.Connect the circuit as shown in the schematic
2.both sensors have been gone for an individual trial
3. start defining the pins on the IDE
4. we upload the code
5. we try to move around the Microwave sensor while it is dark and while it is light and see the difference.

Fabrication/Implementation Process

Explain the fabrication/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

The sequence of the Code:

1.We define pins function

2.We start asking the sensor if it is light or dark and if there is a move or not

3. while it is dark and there is a move then it will trigger the LED and the Buzzer

4. in Case of light nothing will happen

#define Sensor 2

#define LED 3

int LDR = 7;

int Buzzer = 9;

void setup() {

pinMode(Sensor, INPUT);

pinMode(LDR, INPUT);

pinMode(LED, OUTPUT);

pinMode(Buzzer, OUTPUT);

}

void loop() {

bool Detection = digitalRead(Sensor);

if (Detection == HIGH && digitalRead( LDR ) == 1) {

digitalWrite(LED, HIGH);

digitalWrite(Buzzer, HIGH);

}

else {

digitalWrite( Buzzer, LOW);

digitalWrite(LED, LOW);

}

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?

I asked for a lot of help from my instructor at my first try with the DC motor and I had the right code but it didn't work with my Arduino

My group mates helped me a lot to debug and check my code

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 project?

A lot of challenges this time:
I had my Arduino damaged

I had to learn more about using bool function also and statement

I learnt a lot about if statement

I tried a lot of projects and most of them failed

I was bad at managing time for week 7 and 8

Final Project

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

I learned to use the If statement better and also it was great to use more than one condition

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: Pre-activity, examples, exercises, or any mini-projects.
