Is it possible to select just one pattern, so every time the circuit is switched on, it only produces that pattern?

[@rengganisotofashionpekanba4933]

Can you do it with the speed button and pattern change button manually?

Can you please adjust the code and add a switch to start the whole process when it is pressed and a buzzer for a Christmas song to sing alongside the LEDs please :)

[@ashrefashref-pu3wj]

i dont have the little conecture what i do

[@Science_4U_]

Hi friend, which connector are you talking about?. Is it the breadboard where are the LED bulbs are inserted?

[@naseemaharoon165]

Sir my LED are working but it is very very low voltage didn't see at cleared in the code need to give little more voltage what can i do

[@Science_4U_]

I think you used a higher value of resistor. You have to use 220 ohm resistor only. Otherwise you can remove the resistor also and work for short amount of time. This gives maximum brightness, but can damage the LED bulb if used for a long time.

[@HaroonSidheeqpp]

Ok sir

[@CharlieLines-vg6lg]

can someone please copy the code and paste it here because i cant open both linkss by the wayyy this is niceee

[@Science_4U_]

Hi friend. I am glad that you liked the video!!! I am not sure why you are not able to open both the links. It is a lengthy code. I tried pasting it here. But only a portion of the code is getting pasted here due to character limitation. Can you give your email id? . I will send the code directly.

[@user-jd2vn9jh8e]

Where the battery negative is connected?

[@Science_4U_]

Hi friend. We are powering all the LED bulbs from the Arduino Uno. Hence, only the arduino needs to be powered by battery. The +ve terminal of battery is connected to Vin pin of Arduino and -ve terminal of battery is connected to GND pin of Arduino, which is next to the Vin pin.

[@user-jj4bj5xp7z]

Do I need to do any changes in code if I replace blue leds with white ? If yes please explain the changes in detail

[@Science_4U_]

Hi friend..There is absolutely no change required in the code. You can use it as such..

[@Producciones_Y_Sonido_Rojas]

Se puede hacer con cualquier tipo de LEDs? Soy estudiante

[@Science_4U_]

Si amigo, claro. Se puede utilizar cualquier tipo de LED y funcionará. Pero no se puede utilizar un LED grande que consuma más de 40 miliamperios porque arduino sólo puede proporcionar esa cantidad de corriente.

[@teclem8156]

no se necesitan resistencias?

[@Science_4U_]

Hola amigo. He conectado una única resistencia común de 220 ohmios a todos los terminales negativos de la bombilla LED. En realidad, es mejor tener una resistencia separada de 220 ohmios conectada al terminal positivo de todas las bombillas LED. Pero también funcionará una resistencia común conectada a todos los terminales negativos de las bombillas LED, como he hecho yo en este vídeo.

[@harsharupasinghe2808]

How use speed control (preset) ?

[@Science_4U_]

Hi friend. You can control the speed of the lights blinking ON and OFF by modifying the code. In the code you can see that under each pattern there is a constant called "int t=80". This constant 't' gives the milliseconds time delay between bulb switching ON and OFF. You can increase or decrease this value for changing the speed 🙂

[@user-du4eu2by5i]

what library should i use in this?

[@Science_4U_]

Hi friend..There is no need to install any library for this code to work.

[@robitasalingay3851]

How long the life of bulb or how many hours the life of bulb?

[@Science_4U_]

The bulb will last for many hours friend. I have not tested. I think it will definitely last for more than 1000 hours. You have to use the resistor correctly to limit the current through the led bul. Without resistor, the life of led bulb will come down due to overcurrent through the led bulb.

Hi dear friend..The code can be downloaded from the google drive link given in the description box below the video. .

[@evpa71]

hey can i put the led + to anything of digital inputs?

[@Science_4U_]

Hi friend. Sure..you can put the LED + to any of the digital inputs. There are a total of 14 digital input pins ( number 0 to 13 ) which serve as digital output pins also. You can connect led + to any of these pins. Only thing to note is that pin no. 13 has a built in resistor, so you can connect any led to this pin directly without any resistor in series. But for all other pins 0 to 12, you NEED to connect around 220 ohm resistor to the led in series, otherwise the led bulb will get burnt out due to over current..

[@Stagmike]

​@@Science_4U_Okey I asked because I have a funduino mega with a lot of dig. Ins

[@ashlygalang274]

can i use more led in this?

[@Science_4U_]

Hi friend. It is difficult to use more number of LEDs since I have already used all the pins in the arduin uno by connecting LED bulbs. However, if you want to use more number of LEDs, you can use arduino mega, which has more number of pins than arduino uno..

[@TempleGuitars]

Is the process of using the Arduino mega the same as this? @@Science_4U_

[@samiqra1538]

​@@Science_4U_ can i use shift register for more led's as same coding or need modification. Let me know what kind of modification

[@ashlygalang274]

Will it work if I just connect the LEDs in series? @@Science_4U_

[@Science_4U_]

Yes friend. Arduino mega has more number of output pins.So you can connect more number of LED to it..

[@sarahellsworth7196]

You need a separate 220 ohm resistor for every led. This is poor circuit design and can damage your Uno

[@Science_4U_]

Yes..you are absolutely correct. I have done this for simplicity only.

[@Science_4U_]

If we have a separate 220 ohm resistor, equal current will flow through each LED irrespective of the number of LEDs lit up during each cycle, leading to uniform brightness accross all bulbs..

[@Science_4U_]

In my circuit, the total current will be same in each cycle as it is a commom resistor for all LEDs and hence if two LEDs light up together, the current through each LED will be half and hence the brightness keeps on varying depending on the number of LED bulbs lit up simultaneously..

[@Science_4U_]

This is the difference I can see. But I can't figure out why it can damage the UNO board. Is it because the current through each digital pin dynamically varies during each cycle depending on the number of LEDs lit up together? Can you please explain?

[@Abyssalism]

I think no damage , each pin can support arround 40mA current, near the limit when only one is connected. You used 9V external battery so current is (9/220) A. 41mA without leakage account.

[@ModelSceneryTutorials]

The code is incomplete. there are only 15 patters in the code that is available to download. Please put up the entire code.

[@Science_4U_]

Hi friend. What you told is correct. In the code only 16 numbered patters are there. But inside each pattern also, there are multiples patterns. If you see, in pattern 1 all LEDs ON can considered as one pattern and all LEDs OFF can be considered as another pattern. Thus, there are more than 16 patterns in the code.
