Final Project Journal
Project Ideation
1- Tell us about the idea of your project. Why do you care about this? What were you inspired by? Include images and videos of similar projects
The main idea is to have lampshades for kids to light automatically when the light in the room is off and the lampshades shaped like two dinosaurs breathe the fire from their mouths reciprocally.
Project Construction
2- Explain the CAD process of your project. How did you use the software to design your project? (List the softwares/tools/materials...etc that you used)
Sketch Design
1- after choosing the design I started to draw the first sample on the paper and I cut it.
2- building a cardboard model with same dimensions of the paper sample
CAD Process Steps
3-Then I started to build the design on the fusion 360
4-build an accurate design for the side face
5- extrude the design
6- duplicate the side
7- drawing the mouth side
8- extrude the design
9- duplicate the side
10- adding the bottom part after extruding it and adding the t slots and the joints
11- adding the front part after extruding it and adding the t slots and the joints.
12- adding the Top part after extruding it and adding the t slots and the joints
13- adding the Back part after extruding it and adding the t slots and the joints
14- adding the component cover part after extruding it and adding the t slots and the joints
15- Adding the components (Arduino) from the Grape cad website
16- Adding the components (H bridge) from the Grape cad website

17-All parts assemble
18- Exporting all parts as DXF files
Tools
Fusion 360
Grabcad website
Cutter
Cardboard
3- Explain the fabrication process of your project. How did you use the machine to fabricate your project? (List the softwares/tools/materials...etc that you used)
Laser Cutting
Laser.mp4After exporting the DFX files I uploaded the exported DXF file to Laser-works & sat the parameters I adjusted the setting of the laser cutter machine to 25 speed and 65 power, opened the DFX file, then named the files & downloaded them to the machine.
After that I set the origin point of cutting & tracked the design space frame, then I started the cutting process which took about 5 min to finish the design.
Tools
Project Electronics & Power Management
4- Describe your electronic circuit. What are the input and action components? What is the function of each? How do the components integrate together to form your smart system? (List the softwares/tools/components...etc that you used)
as shown in this circuit, I am controlling two lamps in manual mode with on/off switch controls and in automatic mode with an LDR sensor.
the LDR sensor sends the light state to control two different lamps.
When the Two lamps light reciprocally with fade.

9v Adaptor
LDR sensor
Crocodile Clips
Arduino Uno
12v lamps
on/OFF Switch
jumper wires
5- What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)
in the beginning, I used the 9 v adapter as a power source because the Arduino needs from 9- 12 V. And finally I used a 12v adapter because I need more power for the 12V lamps.
Project Programming
6- Describe the code of your project. How did you program each function of the project?
I started by identifying the pins (9-11) with the H bridge, then the on/off switch with pin 4.
I set the function of every pin I connected (9-8-7-12-11) for the Tow lamps from the H Bridge and 2 as input from the LRD sensor. and for pin4 made it as input pull-up to make sure the state stays HIGH. When we press the button, the states become LOW.
I added the if condition to control the effect of the on/off switch.
to make a variable value use a value range from 255 - 5 to make the fade effect reciprocally between the two lamps.
when the LDR sensor takes an input ( the room light is on ) it turned the Lamps off and when the LDR sensor takes an input ( the room light is off ) it turned the Lamps on.
I added the else condition to Complete the If condition, so when the button is off else started.
Project Integration & Testing
7- Demonstrate with text and visuals how did you integrate the project’s modules together? What are the testing results? (Include a Demo video separately, showing a proof of functionality)
in the beginning, I connected the circuit and test it to make sure all functions are working.
the on/off switch opens and closes the circuit and the LDR sensor takes an input ( the room light is on ) to turn the Lamps off when the LDR sensor takes an input ( the room light is off ) it turned the Lamps on.
the second stage is to build a cardboard model and create a suitable place for the circuit component and test the overall look and note the problems to fix them in the final stage.
the final stage was to design the final shape in fusion 360
and convert the file to DFX files and cut it with a laser cutter machine and assemble all parts and make the final test to make the last edits

8- 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?
I asked many times for feedback from my colleagues and the instructors the best one came from yousra, she suggested adding a whiteboard and colors and I think this will be a very good feature, Mohamed Hussein suggested adding a servo to control the mouth movement and I added all of this to nice to have stage .
Overcoming Challenges
9- 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 project?
I got stuck when I saw my proposed final project had been executed by the instructors - I turned to Amany ( my instructor) and she told me it was OK to have the same project with different features.
I paused when trying to draw the first side of my project in fusion because it was so difficult to make it a fully defined shape and after some research, and many experiments I learned how to define the arc and line.
there is a big mistake to depend on the accuracy of grapcad component's dimensions so take the real dimensions by yourself, I downloaded two components from grapcad the H bridge and the Arduino UNO , and both of them are not accurate.
Future Work
10- If you had more time, what is one thing you would change/ Do next in your project?
I will build a small body for the dinosaur and add a whiteboard on its side also will add some colored pencils.
I will add a servo motor to the mouth to give it the ability to open and close and build a direct correlation between the servo and the mount of lights ( when the mouth is fully open we have a higher degree of lights
and when the mouth is closed we have the lowest degree of lights )
also, I will add 4 wheels to the body to give it the ability to move easily
