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)

Design, simulate, and build a simple electronic device that performs two actions. The device may serve a need at your home, or just fun to build!

Railway game

The Railway game is one of the toys that I dreamed of owning when I was young, so it was fun to make it myself.

I tried to implement a similar idea with my design by using pepper to make the model of the train and connect the motor and RGB LED in the circuit which, when we were on the circuit, the light was turned on with a green light. when we switched the switch button, the light turned on a red light and the motor started to work and move the train.

Tool Chain

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

Tinkercad to design the circuit

paper to make a prototype

Electric Component:

on\off Switch

5V adaptor

Slide Switch

Jumper Wire

motor driver

RGB LED

resistor 220 ohm

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?

STEP 1

I designed my circuit on Tinkercad.

I used Mottor and RGB LED as the output component.

I simulate the circuit on Tinkercad.

First I tried to connect the device without an on-off switch to test the circuit with a 5V source.

when we are pressing "on" the circuit, the light is turned on with a red light.

when we switched the switch button, the light turned on a red light and the motor started to work.

then I connect an on-off switch to open and close the circuit.

I connected the switch and the on and off switch in series together and I connected the motor and the LED in parallel.

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?

STEP 1

in this step, I made this circuit with my kit component.

First, I tested all components which used.

then I connect them according to the simulation.

After testing the components, I connected the circuit individually to test it.

1- I prepare the component to be ready to connect with instruction and other components.

started to connect components on a small board.

I started connecting the power socket

and then the opening and closing switch, so that on the positive side of the power socket there is one of its wires, and the other end will connect to the rest of the components.
then I connected the switch so that the middle pin was connected to the second end of the open and close switch, and each of the other two ends was connected to a separate row on the board.
After that, I connected the RGB LED so that its negative is connected to the negative power socket the red pin and resistor on one of the two rows of the switch, and the green pin and resistor on the other.
Finally, I connected the motor so that the pin on the negative power socket and the other pin was on the same row of red.

STEP 2

Design and make the game.

First, I drew people for the train car on paper, then cut it out.
On a piece of paper attached to a cardboard, I installed the motor in the center of the paper, then attached a stick to it with a pen at the end and connected it to outline a circle that would help determine the path of the motor.
I made train track runs like paper rods on either side of the line.
I ensured that the bars' width matched the train car's width.
I made this axis so that it could hold the two carts and attach them to the motor blade by attaching two sticks to a piece of plastic that I cut from a straw.
I prepared the LED to look like a lamp post by twisting the wire onto a stick and placing it in a suitable place where all the wires are close together so that it is easy to connect them.
I prepared a control unit with slots for the on/off switch, power socket, and switch.
In the end, I connected all the components.

Finally ly my Train🚄

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)

When I designed the circuit it didn't work as I wanted the RGB LED worked but the motor wasn't working.

It worked in Tinkercad but did not work with my components.

After research and investigation, I discovered that there was an error in how the components were connected to the electrical switch.

Final Project

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

Tinkercad software

my new skill this week is knowing that it can simulate and test circuits without damaging my components.

WOW!

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

With an awesome team "Lina&Hussien", we could make and control this fantastic car.
