Arduino is an open-source physical computing platform designed to make experimenting with electronics more fun and intuitive. Arduino has its own unique, simplified programming language, a vast support network, and thousands of potential uses, making it the perfect platform for both beginner and advanced DIY enthusiasts.

Circuit 1 Blinking Led Light

Process

This schematic is an average symbol visual of how an LED will light up. The schematic shows electricity ,(volts) travel through the Arduino board. This specific one shows how an LED is lit up as the code allows electricity o travel through pin 13 to the LED light(lighting up ) to the register, to the ground, this is how major of LED (light up ) circuits work.

(Pin 13 is a specific to this circuit but it could connect to any of the pins (2-13) but it is mandatory to have it connected to one of the pins, otherwise you will not be able to call it on your code.)

Circuit 1 original code CODE BY V.P

Product - Changed circuit 1

I changed the first digital write from HIGH to LOW and the 2nd digital Write from LOW to HIGH .The delay has been changed to 10 millisecond ,So the blink was so quick you couldn't see it

The changed quicker circuit

the changed quicker code

Circuit 2 Circuit with Potentiometer

Process

Code for Circuit 2 - Potentiometer to work

The original definition of a potentiometer

Circuit 3 Circuit with RGB LED

Process

The showspectrum code and below the showRGB code

I used the RGB LED to create this circuit and the showspectrum

Circuit 4 Circuit with Multiple LEDs

Process - RandomLED 1

Circuit 4 - random led

One of the functions I did was teh random LED's

Process - MarqueLED 2

Circuit 5 Circuit with push Button

process 1 - (no product)

The code for the circuit using 2 push buttons

Circuit 6 Circuit with photo resister

Process

The actual circuit wiht the photo resister gif

The Pros and Cons

Manual tuning uses fixed numbers that you type into the code yourself, making the LED behave exactly the same way every time you turn it on. It is reliable and won't get confused by sudden flashes of light, but you have to guess the numbers and rewrite the code if you move the circuit to a different room. Auto-tuning lets the Arduino find the room's light levels on its own, so you never have to guess numbers or change the code. It adapts to any room instantly, but it can act glitchy right when you plug it in and will get confused if a sudden bright light flashes on the sensor.

Circuit 7 Circuit with a Temp Sensor

Process - TempSensor +Led

The main code for the program to work (original already there)

The code I added to make the led blink when the temp gets over or below a value

The cirucit I made for this project to work

Circuit 8 Circuit with a Servo Fan

Process- Circuit with the servo

The changed codeI delayed the seconds in between the fan would move to 1,which made my fan move quicker

Here is my circuit after changing the speed and now its quicker the actual circuit

Circuit 9 Circuit with the Piezo element

The orignal circuit with the orignal code for the song take on me

My new changed circuit wiht the piezo element for the supermariobros song!

My changed code to make the supermariobros song

Circuit 10 Circuit with a spinning motor

The motor function code that makes this circuit to work properly

The code I had to turn off and turn on to make it work

The circuit with the spinning mototr,diode and transistor with more speed

Circuit 11 Circuit with relays

The main code needed to make this circuit using the relay

Circuit video with relays.The red and yellow light blink one after another like the traffic light

Circuit 12 Circuit with the Shift register

Process- Perform 2 functions

This void loop functions keeps in all the different functions where I coudl enabel or disabel them accordign to which one I want to use

Oneof the function was one after another

Here is my circuit setup but an error occured in one of my appilances(board,led,wires).The circuit was buitl right btu there was a fault in the board whch cannot be fixedTo fix the problem I step by step looked at my cricuit with the original crcuit and after that allgned I looked up the cod which was perfect too.But afetr finding no problems wiht that I realsed there was a fault in of the appliance

Another function was the One at a time
