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 about designing, simulating, and building a simple electronic device that performs two actions.
I chose (Water Level Indicator)

My water level indicator is a simple circuit that senses water levels in a container to indicate whether a body of water has a high or low water level according to whether the circuit is closed or open. The concept of this circuit is conductivity. This circuit depends on the water as a good conductor, so it can make a closed circuit.

Tool Chain

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

Software

Tinker CAD
Tinkercad is a free software for 3D design, electronics, and coding,
I used it to design and simulate my circuit.

Components

LEDs

Buzzer

Resistors

Breadboard

Connecting Wires

5v Adaptor

Tools

Glue gun

Scissor

Avometer for troubleshooting

Material

Cardboard for the enclosure

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?

Circuit Design On TinkerCAD

First, I used 3 LEDs to represent 3 levels in the container (OUTPUT).
I used a 220-ohm resistor for each LED.
I put a buzzer to be an alert before flooding (OUTPUT).
I used a switch to be the device's On/Off switch.
I used three other switches to be an alternative to the water by making a closed circuit.
The voltage source in my circuit is a 5v adapter.

Circuit Simulation On TinkerCAD

The 3 LEDs are connected in parallel.
The buzzer and the third LED are connected in series.
The switch is connected with the circuit in series.

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?

Prototyping On Breadboard

Enclosure

Using Cardboard I made a device that has an on/off switch, buzzer, and LEDs.
On the back of the device I made the wiring.

Final Result

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)

(1)

(2)

As shown, the third LED and the buzzer didn't work at GIF(1). But in the GIF(2) it worked, but with low brightness.

I added some salt to increase the conductivity of the water.

Final Project

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

My final project is an electronic kit. Basically, it depends on electronic circuits.

WOW!

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

It is just mind-blowing how we can control things using electricity alone and without coding.

Weekly Digest

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.
