Week 8 - Journal

Ideation

Tell us about your assign ment'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 was to build a simple smart circuit that contains at least TWO action components that you can control wirelessly. and to use either the Android GUI or PC GUI to control the action components. And as it was the last week of MD and it was time to go rock the world with our projects. I was inspired by the traffic lights and how cars move to their destination by just changing lights. So here we goo.

Tool Chain

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

The software used for the assignment:

TinkerCad circuits building and simulation online tool

Arduino IDE

The Hardware:

Arduino UNO
Bluetooth module
Jumpers wires
Buzzer (5V)
RGB LED
3 1k ohm resistors
3 330 ohm resistors
Cardboard

Design/Preparation Process

I dragged and dropped the components of the circuit in the design workspace in Tinker CAD

1- I connected the GND and 5V of the Arduino to the breadboard.

2-I connected the three anodes of the LED to three 330ohm resistors and the Arduino pins (3,5,6). And the cathode to the ground.

3- I connected the buzzer negative part to the ground in the breadboard and the positive one to pin 11.

4- I then connected the bluetooth module to the breadboard where I connected the GND to the ground, VCC to the 5V, TXD to the TX, and RXD to a 1k and 2k resistors then to the RX of the Arduino.

Coding:?

Serial . begin 9600
- Specify the output : ( RGB LED , buzzer )

void setup :

{ while serial avaliable =0} to the clarification that output will not work without value

{ incoming data = serial read } the value that will come from the Arduino control app will save on it

Specify every button what will do :
button1 : blue led will work
button2 : green led will work
button3 : red led will work
button4 : buzzer will work

and delay (1000)

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 wiring the Bluetooth module as I didn't fully understand it from the videos, and I aactully burned one trying to wire it. So I asked Twancy; an MD alumni who told me the right way to wire it.

Final Project

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

I got more confident with writing code and debugging and I guess it will really help me later with my final project .

Weekly Digest [OPTIONAL]

I worked with my friends SALMA and AHMED to make the coolest robot arm. It was really fun and delightful project that got me excited for my final project
