I used arduino uno r3 board. While uploading the code it is showing error. And is it necessary to join a wire to ground on both the sides of the arduino uno. My battery connection is directly with the circular port on the board. Is it fine or there has to be a wire connected to gnd on both sides of arduino uno

Hi friend. There is no need to join ground on both sides of the arduino board. They are internally connected.

Good video! Just wondering how you were able to add only one resistor in the circuit instead of having one resistor per LED?

@Science_4U_

23 күн бұрын

@Jenkinsoup Hi friend. Thank you!!!. Having a single resistor for all LED bulbs is the proper way to do. That ensures same current through all LED bulbs irrespective of the number of LED bulbs lit up together at an instant, and so same brightness. But, the way I did is an easier way to do. But the drawback is that the total current remain same in the circuit. So if more number of led bulbs lit up together, the current passing throufh individual LEDs will be lower and hence their individual brightness will be lower. This is the difference.

@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.

Is it necessary to add the 220 ohm resistor?

@Science_4U_

14 күн бұрын

220 ohm resistor is connected to limit the current through the LED bulbs so thst it will not burn out. However, Without 220 ohm resistor also it will work since many LED bulbs are simultaneously lighting up. This limits the current through the LED bulbs. Also the bulbs are just flashing. So bulb will not get enough time to burn out. So directly connecting without 220 ohm resistor also will work. But it is not a recommended practice..

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

@Science_4U_

3 ай бұрын

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.

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.

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

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_

Жыл бұрын

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_

Жыл бұрын

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.

@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 🙂

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..
