Week 5

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 idea is to make a small device with simple things, and design the circuit yourself on Tinkercad before implementing it on the breadboard.

My idea for this week was inspired by cars and robots, and I found these ideas that I really liked while searching on Google. I will do something similar in my own way.

Tool Chain

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

For circle design

I will use Tinkercad to simulate the circuit before you send it to the breadboard

For the electrical circuit

Jumper Wires.

Pouch Botton

on/of switch : To open and close.

Adaptor 9V :The source of electricity.

Hobby Gearmotor: To move my small car.

Small breadboard: To connect the circuit.

Resistor 220: For the LED.

LED: I will use 2 LEDs, one lights up when moving forward and the other when moving backwards.

For the body

I will use a hot glue gun to glue the cardboard and make the body.

I will use scissors to cut the cardboard to make the body.

I will use cardboard to make the body.

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?

First, I opened Tinker cad and created a circuit, then I chose the circuit component I mentioned earlier.

Then, I started by connecting the power supply to the board, then I connected the positive of the motor to the power supply and the negative to the negative, and I did the same with the LED. Before connecting the negative of the LED, I connected a resistor between the power supply and the negative leg of the LED to reduce the voltage to protect the LED from damage.

After connecting the circuit in parallel, I moved to the next step.

Second, I had to connect the switch button, so I put it in the circuit and connected its middle leg to the negative of the power and connected an external leg to the on and off button and connected the other leg of the stop button and the other leg to the resistor and thus the circuit became complete.

Then I tried the simulation to make sure the circuit works.

Simulating circuit

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?

First I started by gluing parts of cardboard to the motor to make the body of the car.

After I covered it from all sides, I started making the wheels and used cardboard to make the front wheels and for the rear wheels I used water bottle covers.

After that, I connected the front wheels by gluing toothpicks to them and then placing them in the small gap in the motor arms.

Controller (electrical circuit) (:

Glass covers for rear wheels

For rear wheels

As for the hidden wheels, I cut a small part of a suction cup and glued it using a glue gun and passed a toothpick through them.

After that, I moved to the electrical circuit, which I had connected as I explained previously, and made a shape like the shape of the remote control from cardboard and glued it to it.

Then I connected the motor to the circuit

Connect the circuit as shown above to the board.Connecting the circuit as shown above on the board, I started with the LED and the buttons.

Then I connected the positive and negative voltages.

The last step was to connect the positive terminal of the adapter to the electronics and the negative terminal to the internal terminal of the switch button to control the circuit.

Now my little car is ready, along with the remote control.

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?

Working with my team members Arwa and Farah to make the car helped me a lot when working on my project.

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?

The problem I faced this week was that after I connected the circuit to the board, one of the LEDs did not work, so I started to check the connections to make sure if everything was connected correctly, and it was connected correctly ,The other solution I thought of was that maybe there was a wire that was not working or something, so I brought the Avometer and started to check all the wires and components, and it turned out that the led was not working from the beginning, so I replaced it with another one, and yes, it worked.

Final Project

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

What I learned this week designing on Fusion to make a cart that will move while taking into account all the space for components and connections will help me when I make my 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?

Working with my team to build a car to compete against the other team was the best thing this week

(we won by the way) :)

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.

Here is other cool Mini Project i have done this week
