Final Project Journal

I worked in many different programs to finalize this project and to make the idea is real between or hand and the first program is Fusion 360

I was used it for make the design (CAD) I make the sketches then I make the extrude and other process for each part as it need to reach the best image of my imagination about it and also it is depended on measurements for component like Stepper motor and its driver and where I well put them in the project and I used GrabCad.com
to get the designs for this parts (Arduino Uno-Stepper motor-driver A4988-Ultra sonic sensor-on/off switch -lead screw and its nut-linear bearings-coupling )

I was make a sketches for all parts separately in a new tab and I go in a Base part and I insert all of them and make a projections for some and joint each part with the related part and bulled the design as I want and here a Video for the sequence

Also I was used a
makercase.com
to make a boxes as a cover for wiring and electronic component in back of the design and as a holder for the bottle of soap or sanitizer

• After I finished my CAD design on Fusion 360 I export two types of files for fabrications
  
  

• The First one it was with extension STL and that for 3D printed parts (4 Parts)
  and I was toke it to Prusa Slicer to print it on the 3D printer M/c (Prusa i3MK2S) that was in the Fab lab
  after I put the parts on the program I change the print settings to 3.5mm & infill to 15% then I click on Slice now to knw how much Grams and time they will toke and they toke as in the picture around 3 hours & half and 66 Gram of filament then I click on Export G-code and the program gives me another file it was have the coordination for the m/c I put it on SD card with the m/c and I make the configurations for it like preheated the nozzle and the bed then select my file from the SD card to print it
  and for the material I chose the black PLA filament
  
  

• the second files was with extension DXF and this extension is for the cutting parts on the laser cutter M/c and my design was needed to cut 14 parts
  I toke them on program called Laser Work V6
  by Importing them file by file and alline between them and make sure that each part is inside the working area boundary then I select all the parts and chose one color then go to the cut settings on the top right and make sure that is a cut not scan or something else then select Max power 65% and speed 22 or 23m/s
  and this sittings and values because I used a 3mm thickness plywood

In my circuits I used :

1. Arduino Uno as a controller

2. Stepper motor as an output

3. ultra sonic sensor as input

4. Pushbutton as input

5. On/off switch

6. 9v adaptor as a power source

7. Data cable for uploading code to the Arduino and also as source of power for Arduino

8. Stepper motor driver A4988 With its expansion board

9. Mini bread board

10. Jumpers

11. Connector for power cable

• I was wire between them like in the schematic in the picture
  and I cant't used tinker cad for wiring or simulation because it didn't have stepper motor or its driver
  

• I used Arduino IDE for compiling the code and here it is like in the photos here and the code is in GP folder inside Assets
  

• The device work when the user but his/her hand under the sensor to get the liquid from the bottle or he/she can use the device by clicking on the bush button on the left

I used the:

• 9v adaptor as a power source for motor and its driver after I added a connector for it in the design body
  

• data cable for uploading code to the Arduino and also as source of power for Arduino
  
  

• also I can use a 6V adaptor to feed the Arduino by power
  

• I made an on/off switch to reduce consumption and to save the component in the emergency cases

its work perfectly but some times the ultra sonic sensor doesn't respond to my hand moves and I need to go up and down with making my hand straight and its work good with a straight services like a ruler or a plate
but in another level it is response good with the push button without any lag or problems

and I think the cover need to have more size in the future because the wires does not make any problems

also the push plate that are pushing the bottle need to be from PLA not wood

Yes of curse and I want to thank every one helped me specially

Eng. Mohaned and its efforts with me in last two days in CAD and Fabrication and He was told me about makercase.com this site is like an automatic box maker just by given them the dimensions this site helped me a lot to reduce the design time because I was make the holes and tabs of the covers and the boxes in my design manually
also
Eng. Menna She helped me in a fabrication

Eng.A.Saeed ,Sherif & Mego for your efforts and patience with me along this happy & useful journey

I stuck A lot of time with CAD
And I Asked the specialist in the lab and Instructors and my peers and by see videos on Youtube
I learned from every one in this diploma something new in each time
And the mistakes was happened because I am work under pressure And with a little sleeping time in my day because of my work and the diploma are taking all my time.

so I need to mange my time more and more to avoid any thing like this in the future.
