Week 8 - 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)

RGB lamps

This week's assignment idea was to build a simple smart circuit that contains at least two action components that you can control wirelessly and use either the android GUI or PC GUI to control the action components.

I love lights and lamps very much so i think that it will be cool to control a lamp lights wirelessly.

Inspiration

Tool Chain

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

I used Tinkercad to design the circuit , the resistor calculator to calculate the ohm of resistor , Arduino IDE to write and download the code on the Arduino UNO and

Materials : I used a 9 volt adapter , Arduino UNO , Bluetooth module (HC-05) , RGB led , 3 resistors 220 0hm , 1 resistor 560 ohm , 1 resistor 1000 ohm, buzzer, large Breadboard , Jumper wires.

Arduino IDE

Arduino Bluetooth Control

Tinker cad

Resistor calculator

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?

Tinkercad circuit

My circuit in Real

I start to design the circuit using Tinker cad .

1- I connect the 5v pin of Arduino to positive of the breadboard and the GND pin to the negative of the bread board.
2- I connect the buzzer directly to the Arduino the negative terminal to GND and positive terminal to pin 11.
3- I connect the RGB led negative terminal to GND , Red terminal with 220 ohm resistor to pin 2 , Green terminal with 220 ohm resistor to pin 3 , Blue terminal with 220 ohm resistor to pin 4 .
4- I connect the TX of the HC-05 to the RX of the Arduino.
6- I connect the TX of the Arduino with 560 and 1000 ohm resistor to the GND then i take a wire after the 560 ohm resistor and connect it with the Rx of the Hc-05.

First : I define my pins to make it easier when i call them and incomingdata that will come from the Arduino Bluetooth control.
Second : Then in Void setup i define the pins output.

In Void Loop : I used while condition means that while there is no incoming data there is nothing will happen.

Then I use if and else if and else conditions :

if serial read is 1 the RGB led will be blue and if serial read 2 the the RGB led will be purple and if serial read 2 the the RGB led will be purple and if serial read 3 the the RGB led will be cyan and if serial read 4 the light will turned off .

In void loop (Finally) : If serial read anything else the buzzer will turned on.

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?

I connected everything like i made in Tinkercad

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?

Micheal Henry and Yasser Hassan helped me to figure out how to upload the code because there was an error that i didn't understand . They told me that to remove TX and Rx pins from the Arduino before uploading because Arduino use this pins while he upload the 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 assignment?

I got stuck three times first i didn't know how to connect the HC-05 but when i followed the circuit in videos wire by wire i make it finally .

second time when i upload my code and everyone helped me in slack community.

Third i didn't find the HC-05 Bluetooth name and Micheal told me to pair it first with my mobile.

Final Project

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

Honestly my final project against using mobile because my idea to stay away from mobiles not to use them.

WOW!

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

we made an arm robot in the end of week session and it's very interesting and fun to me.

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.
