At first we will think that it just be a multi-colored office lighting unit, but this is not like any lighting unit because when you see it from the first moment you will smile despite you because it contains a sentence with an optimistic meaning and is designed in a fun way.The words of this sentence move outward and inward in the manner of Kinetic art, along with distinctive lighting. We can control its colors by telephone.

the design

my design contains 3parts

( 2.5d wooden+acrylic body , 3d words .3d mechanisms parts(rack and pinion) )

process of 2,5d wooden body

2,5d lighting unit with fusion360 (cad) / laser cutter (cam)

dimensions 2,5 model (130mm*130mm*340mm)

dimensions mdf board (600mm*425)

dimensions acrylic board (100mm*120)

cut (25 speed,50 power)

took (15m) fabrication

# fully defined sketches

#design sketching with dimensions (130mm*130mm*340mm)mm

3- design a 2d sketch with different tools such as spline, circle, rectangle, and some features such as constraints and circular pattern .

4- after that, I add T- a slot and interlocks to assemble later, fully defined all elements I designed by dimensions and added 2d pattern

# adding pattern

#extrude the sketches to assembly

I finished the sketch and extruded all faces to get 2,5d design then I assembled all parts to get my shape

# render

# version 1

# version 1 inside body with components

Fritzing is a great open source tool for anyone to teach, share, and prototype their electronic projects! It allows you to design a schematic, and thus a part, which can then be added to very professional-looking wiring diagrams. You can even design your own PCBs and have them fabricated from the files you design

the main reason for using this software because tinkercad didn't have more components and fritizing has advantage (downlaod component file which you want)

Arduino is a coding software use c++ language for code and its communication language between Arduino board and electronic components by coding language and i connect board with software by USB cable

materials (electronic components)

my inputs

slide switch

push button

bluetooth module

my outputs

3 servos

rgb strip

circuit describtion

my flow is run 3 servos one after one from zero to 180 angle and lighting rgb strip and control it by bluetooth module and phone app

circuit connection describtion

-5v regulator has 3pin (input power,gnd ,out power) so i put it in breadboard to put servos after that with it

-servo has 3 pins (gnd,power and pin connect with Arduino) so i put servos (gnd,power) pins in common (gnd,power) of 5v regulator in breadboard pins and put their third pins in pwm pins in Arduino

-adapter has 2 pins (gnd ,power) so i put them in pins in common (gnd,power) breadboard pins

-Bluetooth module has 6 pins but we need just 4 (vcc,gnd,rx and tx) i connected rx pin with 2000 ohm resistor pin by using 2 resister (1000 ohm) connected with each other by sires way and another pin of resistor with tx pin in Arduino , tx pin in blu connected with rx pin in Arduino , gnd pin in blu with 1000 ohm resistor (connected with 2000 ohm resistor by parallel way) another pin of 1000 ohm resister with common gnd in breadboard ,vcc pin of blu in common power in breadboard

-rgb strip has 4pins (common anode,red,blur,green) so i connect 3 colors of it with h bridge and anode with common pwer pin in breadboard

-h bridge driver has more pins but i used (vcc,gnd,en1,en2.en3,n1,n2 and n3)pins to connect rgb strip with 12v adapter and arduino so i connected vcc and gnd pins in common (gnd,power)in breadboard , en1,en2and en3 pins of h bridge with red,blue and green pins of strip , n1,n2and n3 pins of h bridge with pwm pins in arduino

-finally in connected slide switch and push button wtih pins of arduino and gnd pins with common gnd pins in breadboard

the arduino should be powered by from 7 to 12 volt so that he can regulate it to 5v

so i used arduino to powerd 3 servos ( which need 5v to work) with common gnd and regulater with adapter to help them get the current they needed

my flow is run 3 servos one after one from zero to 180 angle and lighting rgb strip and control it by bluetooth module and phone app

area before (void setup) uses to define any initial character which Arduino doesn't save in its programing language

-so i summoned libraries of Bluetooth module and servo and tell arduino they are exist by (#include) function

-The (SoftwareSerial library) allows serial communication on other digital pins of an Arduino board, using software to replicate the functionality and { (0,1); } are tx and rx pins of bluetoothmodule

-then i define servos , switches , rgb leds pins by (servo,#define) functions

-finally i define angles of servos by (int) function

The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup() function will only run once, after each powerup or reset of the Arduino board.

-i initialize (servos,switches,rgb leds) pins in arduino,tell arduino what is input and what is output by (pinmode) function

-i specify the angle positions which the servo will start by (myservo.write (0)) function

-(Serial begin) establishes serial communication between your Arduino board and another device,That number(9600) is called the baud rate. for serial communication to work the baud rate in Serial.begin() and the baud rate set on the receiving device need to match , so i used (serial.begin and blu.begin) functions to matching baud rate of them

- The println() method writes data to the serial port. This is often helpful for looking at the data a program is producing or to write data to other devices connected to the serial port. The println method works like print, but sends a new line character for each call to the function. Data can either be a single int, float, byte, long, char, char[], String or a number in decimal (DEC), hexadecimal (HEX) , octal (OCT), or binary (BIN) base , so i used (serial.println ) function to initialize bluetooth mdule to control from another device

NOTICE use cotation marks to initialize any initial you but in this function

-(setcolor) function It takes 3 parameters, about the values to be written to each clored LED

-(delay) function Pauses the program for the amount of time (in milliseconds) specified as parameter. (There are 1000 milliseconds in a second.)

the loop() function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. Use it to actively control the Arduino board.

-The ( if()) statement allows you to make something happen or not, depending on whether a given condition is true or not. so i used it to controlling (push button ,slide switch) modes

-The (for statement) is used to repeat a block of statements enclosed in curly braces. An increment counter is usually used to increment and terminate the loop. The for statement is useful for any repetitive operation, and is often used in combination with arrays to operate on collections of data/pins. so i used it to control servos angles (limits,motion speed )

-(digitalread) function Reads the value from a specified digital pin, either HIGH or LOW. so i used it to read (swtches)

- An (else clause) will be executed if the condition in the if statement results in false. The else can proceed another if test, so i used it to stop servos in zero pos if i off slide switch

-A (while loop) will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Something must change the tested variable, or the while loop will never exit. This could be in your code, such as an incremented variable, or an external condition, such as testing a sensor. so i used it to control (blu.available) function

-The Serial.available( ) function in Arduino gets the stored bytes from the serial port that are available for reading. It is the data, which is already stored and arrived in the serial buffer. The serial buffer in Arduino holds the 64 bytes. -constrain() Constrains a number to be within a range.

-Serial.flush() Waits for the transmission of outgoing serial data to complete. (Prior to Arduino 1.0, this instead removed any buffered incoming serial data.)

(void) The void keyword is used only in function declarations. It indicates that the function is expected to return no information to the function from which it was called. so i used it to declare pins of rgb strip to light

1-i print rack and pinion mechanism to test it with servo with sweep code

www.thingiverse.com/thing:3170748

3-print i element and cut by laser cut (shelf with part of front) to test mechanism with this element

4-i connect rgb strip with bluetooth module and phone app

5- connecting servos together by code

code of servos drive.google.com/file/d/1ng4wjuLooLRwB5DZ_ChKOAA9w733pLUL/view?usp=sharing

6- combine rgb with servos

7- assemble body

finallyyyyyyy

say hi to elfeel_dya2

look to cool lighting

look who is here!

• in code i was confused how can i control 3servos controlling (speed,angles) and combine it with rgb code so esraa and mahmoud hepeld me in this situation to fix code and combine tje 2 codes

• i don't know how i can connected 3 servos which needs 5v with 12v adapter so sherif tell me to use 5v regulter to protect them from burning

• and the way to connect rgb with arduino and giving it 13 v from adaprrt in the same time so esraa tell me using h bridge driver to do that

• i have an eror when i combine controlling 3servos code with rgb and bluetooth module code in scoop of (setcolor don't declared) so esraa discover that i must change the position of this scoop to write it after viod loop area not in it
