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

I always go to bed and forget to turn off the lights so I have to get out of my bed and turn off the switch.

so my project is about turning off the switch remotely from mobile phone

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)

using fusion 360 :

1- a mechanism of two parts is designed then extruded then assembled with servo motor to check the mechanism

mechanism + main

using fusion 360 :

2- the main part that will be mounted to the wall is also designed using fusion 360 ( this part is done by drawing a rectangle then drawing 1 circle and mirroring it many times until we reach the opposite figure )

3- the two cases will also be designed using fusion 360 ( body 1 and 2 was extruded from the shape shown and then circles are cut using cut tool)

main part

body1&2

body 1&2

body1 before extruding

assembly:

first as in figure 1 i assembled the motor with the back part using (joint)

while in fig 2 i assembled the motor head with the front part using (joint)

while in fig 3 i jointed the back part with the component i made to simulate the switch

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)

using the 3d printer:

mechanism and main part are printed

using 3d printer :

body1&2 are printed

body1

body2

3d printed parts

mechanism&main.dxf

using the laser cutter :

I used 1 wooden plate to cut the file it took 9 minutes

using 3d printer :

body1&2 are printed using 3d printer

body 1 took 2hours48 minutes

body 2 took 1houre 38 minutes

I used grey PLA

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)

the device is controlled using Arduino Uno

for the input components :

Bluetooth module is used to take input from user

for the action components :

servo motor to mobilize the mechanism and the switch

tinker CAD :

note that the ultrasonic sensor is the Bluetooth module as it is not available in tinker cad

the motor is connected to pin 12 while the bluetooth module is connected to 0 1 pins ( tx rx )

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)

the power source was 5v adaptor as the device will not be portable

i used 5 volt because the motor is weak and only applicable on 5 volt

when i used it on 9 volts it got burnt sadly

Project Programming

6- Describe the code of your project. How did you program each function of the project?

code

in this part we including servo library

defining servo pins , angle and state

a loop to take input from Bluetooth module and apply it to servo motor whe 1 angle = 0 , when 2 angle = 180 , when 3 angle = 90 ( default)

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)

demo video

as shown in video it takes input from the smartphone by Bluetooth module and moves the servo motor to move the mechanism to move the switch

Sharing & Collaboration

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?

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?

the problem that faced me is servo motor burnt in the last hour before preview

I had to change the motor in the last minutes lucky for me I had extra motor in the kit but it had a problem where the fitting places for bolts where too tight so I had to mount it with glue and sellotape as a quick solution

the motor was burned because I used 9 volt adaptor at first so I changed it to 5 volts I knew this was the reason because there is literally no other reason

Future Work

10- If you had more time, what is one thing you would change/ Do next in your project?

to use sound sensor to open and close the switch
