Final Project Journal

I started by drawing the basic parts in Fusion 360 and extruded them into 3mm "the wood sheet thickness", then combined and assembled the last parts, then installed the components after getting familiar with how they were integrated into the enclosure with a help from tutorials.

At first it was a big challenge for this part to be extruded like the next pic, however research and watching tutorials teaches how a living hinge part can be sketched and fabricated into Laser cutter machine. But thanks to Ahmed Ibrahim, one of the instructors who guided me through the first steps into this part at an actual moments in lap space, since i get back to google and after changing keywords of search and links of sources, i could finally achieved to a close way of how living hinge can be modeling in Fusion and to be honest it was more than helpful and achievable to the main point i searched for. So, thanks god :) It was a pleasant end as I guess, to reach to this level in the modeling pic.

LED CUP schematic diagram in Fusion 360, customization of materials and physical appearance of 3D printing

Prusa i3 and Laser cutting machines are what i used in this project.

I used the prusa i3 machine to print a cup for the LED strip into 3D, it designed to contain the LED strip by fitting it in a base hole.

After designing it using Fusion 360, i went to Ultimaker Cura software to set up an STL design file.

Next, as I did in the LaserWorks software, I have to set the required dimensions and whether there is any supports needed to estimate the grams consumed and the time that will be spent in the 3D printer. (In my case with the LED cup, I didn't need to put in any supports in that position as it normalize the cost of time and grams consumed)

Therefore, I converted the final design to G-code and uploaded to the Prusa i3 machine to print the cup.

I should note that when working on a 3D Printer machine, I have to let the machine (Nozzle) configure the dimensions of the bed to be worked on so that it does not print in a place outside the specified area.

Also, Let us DO NOT forget setting the Filament to Generic PLA means that Nozzle temperature will be 215°C and if was not that I need to check it.

Finally, I sliced the model to estimate the cost of time and grams involved, then I converted the final design file to G-code with a new name as following: “Prusa i3_LED CUP_5g_22min_PLA_0.3Q” and downloaded it to the Prusa i3 Printer by SD Card.

Well, at first, I went to the Arduino IDE app to text the code required to run the circuit in a hands-on state using the list of components including basically the Arduino Uno board and push-button switch.

Then it's time for the electronics kit to get the tools required to build the "hands-mode" circuit and test the circuit with the previous mentioned code.

The electronic circuit for hands mode contains:

• Breadboard

• Arduino Uno board

• Jumper & Crocodile wires

• Pushbutton toggle "Input"

• 5v Relay module

• LED strip "Output/Action"

• 9v Adapter

• Selector Switch "Input"

• Servo motor "Output/Action"

The breadboard and Arduino Uno board host the plugging wires of all components, while a 5v relay module is used to emit light from the LED Strip and 9v Adapter is used to power the LED with the voltage. Selector switch and pushbutton are used as inputs as when a message is delivered, the expected action component/s receives the order and performs the desired function, which is in our circuit a role of emitting light throughout click on toggle push button and the selector switch to turn on/off manual mode. Servo motor is working parallel to the LED strip as it rotates 120° with the LED on and rotates 0 parallel with the LED off

Jumper and Crocodile wires were the "invisible soldiers" as they were like the main bridge to all the components of the linked circuit.

Now it's TinkerCad's turn to rebuild and simulate the hand mode circuit with the same components I used on the real circuit.

TinkerCad is a flexible tool for building and testing wiring with components in case the user has to run trials before using a real circuit. The ethical scene behind this is to protect real ingredients from burning or spoiling. It's a tip I've learned that says "feel free to go with trials and unexpected results in tinkercad but be careful with real ingredients"

int Pushbtt = 6;

int relay = 3;

int trig = 8;

int echo = 9;

int Ultra;

int cm;

int Selector = 7;

#include <Servo.h>

Servo Servo1;

int ServoPin = 11;

char action = '0';

int angle11 = 0;

boolean oldPushbttState = LOW;

boolean newPushbttState = LOW;

boolean relaystatus = HIGH;

long read (int trig, int echo) {

pinMode (trig, OUTPUT);

digitalWrite (8, LOW);

delayMicroseconds (2);

digitalWrite ( 8, HIGH);

delayMicroseconds (10);

digitalWrite ( 8, LOW);

pinMode (echo, INPUT);

return pulseIn ( 9, HIGH);

}

void setup()

{

pinMode(relay, OUTPUT);

digitalWrite(relay, LOW);

pinMode(Pushbtt, INPUT_PULLUP);

pinMode (Selector, INPUT);

Servo1.attach(11);

Serial.begin(9600);

}

To implement the idea of the lamp I need to mount the components initially I found myself trying to get and setup a 5V relay module to hook it up to the LED strip which would be connected to a 9V transformer to power the LED using the necessary voltage and the relay would act as a bridge between the Arduino board and the LED, which means giving the command to LED to turn on/off while receiving its request from the Arduino board uploaded to script code before using the Arduino IDE app.

Now, it remains push-button to control the LED action either emitting or blanking the LED, and the selector switch that will turn the whole state from manual to auto mode and vice versa, so i entered all these gadgets in a text code as input except relay one which considered as output.

I can not forget the servo motor and ultrasonic sensor so, i integrated them as well to the las components and write the required code for them as follows:

servo motor has no action in case of Hands_Auto_Mode until the user click on a toggle pushbutton that has a 0 state and with one click it turns the light on and by one another click it turn the light off and so on, so pushbutton is integrated as input and i wrote a PULLUP in the code to inform the Arduino that this button has tow terminals only but if i have a button of 3 pins like a s elector switch i use, then there will no need to write PULLUP.

boolean oldPushbttState = LOW;

boolean newPushbttState = LOW;

boolean relaystatus = HIGH;

in the text code it means that i am giving an order to the pushbutton to not do anything without my permission which means without clicking no action will be no taken "the start point/state is zero".

Now, time of TinkerCad software to simulate the circuit using the same component and wiring methodology

I faced challenges in integrating and assembling parts for manufacture in which some fractures were happened unfortunately during assembling the enclosure, while another one were happened in the lap space after fabrication like the next pic.

The upper part was due to a sketching error while the lower part could not bear the bending enough.
