Week 5 # - 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)

Buzz wire is a steady hand game that is well known to many as a table top amusement. Buzz wire is a challenging and competitive game where you are playing the number of touches against time. The player has to get the right balance between speed and skill in order to obtain the a successful score.

describe of the design process

1- i used Tinkercad software to simulate the electric circuit components and make sure it work like my design and also help me to fix any problem easily

2- integrate all parts on components very easy and give my image about how it will be look in real

3- i used the push button in the circuit as loop cable replacement

I used a 5V power supply because the LED works with 2V while the buzzer needs 5V and by connecting them parallel, each component will receive 5V.

The LED is attached to 220-ohm resistance so it can take the 3V that excess. I chose 220-ohm by applying ohm's law (Voltage= Current*Resistance). The maximum current in the circuit is 20mA. The excess voltage that the resistance will receive is 3V so the optimum resistance is 150-ohm. Thus I chose the resistance with the nearest value which was 220-ohm.

The components that appear in the design are:

Power supply (adaptor), white breadboard, switch , Jumper wires, RGP LED, motor r, and resistors.

I connected the +ve terminal of the power supply with the breadboard.

I connected one side of the switch with the +ve terminal of the power supply. And the other side of the switch is connected with +ve terminal of RGB LED.

Then I connected the resistor with -ve (ground) terminal of RGB LED and power supply.

I took a jumper wire to connect the +veterminal of the pushbutton with the motor. Then I connected the -ve side of the motor with the -ve of the power supply

(parallel cercuit)

why parallel parallel

because parallel circuit comprises branches so that the current divides and only

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?

The electrical circuit is prototyped on a breadboard

1. Negative wire from dc 5 v source

2. Positive wire from dc 5 v source

3. Negative jumper for RGB led common ground

4. Positive jumper for RGB led for green color

5 . Negative wire for Yellow dc motor

6 . Positive wire for Yellow dc motor

7. Bridge to connect the two parts of the breadboard

8. 220 ohm resistance to keep the rgb led from high current

1- I made two towers to be the basis for the design and to carry the cable

2- I designed the hook to make a loop and connect the negative end to the rest of the circle

3- I connected the circuit that I tested on the Tenker CAD and confirmed the connection by testing a lamp

4-I used the yellow motor to hold the flag

5-I used a compass to make a flag stand

6- So I connected the entire circuit including the yellow motor and the lamp

7- After that, I added a switch to disconnect and operate the circuit and be a safety factor

After that I connected the final shape of the circuit and do a cable management and maked sure that the circuit worked

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?

This week's project was individual and I did it at home and the thing that helped me the most was the tutorial videos on the portal, the advice and feedback which I took from Esraa my instructor ,I shared my idea with her and she thought it's a nice idea. I want to thank here again

Also Salma help me the different between the natural colors and

and the light colors to use it with RGP LED

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?

1- I had a problem installing the yellow motor inside the body of the design, so I put it outside the body because I could not integrate it , but Mohab suggest put the motor out of frame and kept using it

also i burned a lot of led do realize the i should use 220 ohm resistance at list to keep it at safe side by using this eq.

Final Project

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

This project will benefit me because I have been trained to implement an idea from scratch and do it with the tools that I had in addition to learning how to connect electrical circuits and implement ideas. All these skills will help me in the 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?

every thing in this week was very cool starting by learning tinkercad, through show a purple light on the RGB LED and write number 7 and all number on the "7-segment display"

But the coolest thing was the buzz wire, I really was happy when I managed to do it and gives my a noise sound at first but i deal with in the end

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.
