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..
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.
@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_You are smart and that would require increasing the voltage of the battery with higher current right? Do you think 💭 it works that way to if I want to sort out the lower brightness?
@Sujal_davda yes..that is correct friend. You can use a break function inside each for loop..use a push button switch and if the output of switch is high, it should break and exit to the next loop for next pattern.

Bonjour, superbe programme pour le modélisme, merci beaucoup. Est il possible de remplacer par SMD type 0623 ? si oui en 5v besoin de résistance ? Et quel Arduino utiliser pour transfert avant l'installation d'un manège 1/87 Merci beaucoup
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..
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 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.
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.
Hi friend. the following is the list of things used in this project. Components used: 1. Arduino Uno Board 2. 9V battery 3. Rocker Switch 4. Red, Green & Blue LED Lights 5. 220 ohm resistor 6. Male to male jumper wires
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..
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..
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?
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.
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..
Hi friend. I will have to make the schematic diagram..I will make and give. Meanwhile you can try making this by watching the video. I am showing step by step in the video..
Hola amigo. He conectado una única resistencia común de 220 ohmios a todos los terminales negativos de la bombilla LED.
