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)

This week's assignment is to make a simple device that has 2 outputs.

after lots of searching and brainstorming, I decided to make a doorbell that works in parallel with a light bulb.

the cardboard design is inspired by an animation movie called "monsters inc." It has the same door, i chose it to be my special door.

Tool Chain

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

For simulating the electric circuit before installing i used Tinkercad software.

And for the device body, i used cardboard.

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?

I took some time to imagine my circuit connections & components on paper then started drawing them on TinkerCad software.

Components:

1- mini breadboard.

2- 220 Ω resistor.

3- push button.

4- on\off switch.

5- LED.

6- buzzer.

Circuit description:

my circuit is designed to perform 2 actions together (outputs) which are light & sound.
I used the 5v adapter as a power supply as the buzzer operating voltage average 4 to 8 V so it's within the value and the LED operating voltage is 2V. so I used a resistor to receive the extra voltage.

Simulation Description:

first of all I connected the (+ve) & (-ve) power supply to 2 points (columns) so these 2 columns took the same charge of the wire connected to it.
next step is connecting the buzzer, push button & LED so, I put a resistor between the 2 sides of the breadboard, connect one of its sides to the cathode of the led and the anode to the +ve power source (on the same column).
jumping to the buzzer, i connected the +ve side to the +ve power supply (on the same column) & the -ve side to the -ve power supply (on the same column).
now connecting the -ve leg of the LED left so, I connected the other side of the resistor to any point on the same -ve power source column.

So far: the buzzer & LED are fully connected from both (-ve) & (+ve) sides. push button and on\off switch are left.

regarding the push button: i connected it towards the positive side from one side and from the other side i loaded the 2 components on it (the buzzer & LED).
The last step was connecting the on\off switch by putting it in front of the power supply points so it can control the whole circuit.

circuit working brief: turning switch on ➡️ pressing push button🟰led lights & buzzer on.

Electric Circuit Simulation

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?

connecting 2 points by the power supply.
connected the buzzer legs with 2 crocodiles & jumpers and put the jumpers` negative & positive sides on the power supply sides.
the lamp and push button is connected with the same connection as in the simulation circuit the difference is that I didn`t connect them directly on the breadboard but i used crocodiles and jumpers instead so i can move them freely.

I used 20*10 cm cardboard parts for both the back and front door sides and made 2 holes in the front side to fit the LED & push button in it.
3 (10*10 cm) parts for the door sides and base, one of the sides has a hole to fit the on\off switch.
and for the door picture, I downloaded one, printed it, cut then glued it to the cardboard.

Whole prototype components.

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)

most of my challenges in this assignment were the connections and why a component is not working with the real breadboard but with the same connections in Tinkercad it's working.
I used maybe 3 or more ways to solve the issues, trial, and error, tracing the wires again & again until I find the problem, also used the AVO in one of the challenges to make sure that the wire is working.
while connecting the buzzer at first i wanted to connect it directly into the breadboard but something wasn`t right and it didn`t work so I replaced it with crocodiles and jumpers at the same place i put the buzzer legs in it before and it worked somehow.
