LED Patterns with Arduino 12 LEDs and 12 Patterns

Utsource is a proffesional elelctronics supplier with more than 2 million product, lower price with free shipping.

Hello and welcome back to creative stuff..

In this video we are going to make an Arduino 12 LED 12 Pattern ,LED chaser.

This chaser is a combination of different LED lights effect. It includes Blinking, running, chasing and random LED effects. It utilizes pin 2 to 13 accommodate 12 LED. In this tutorial we are going to create a circuit with 12 LEDs and program it in various ways so that we have different LED blinking patterns. We are going to experiment with LED as well as with the Arduino random function. We are going to make a random selection of which led to blink as well as a random amount of time for which this LED will blink. The code is very flexible.. you can use the same code for any number of LEDs you want to use by just changing 1 simple thing in the code..at the beginning of the code just add the number of Ardunio pin number.

To make this project we are going to need :-
5---- connecting wires

Thank you. These were some great code examples of different types of scrolling Larson Scanner types of LED patterns.

This is amazing. Can you add a push button to change LED patterns?

[sharvataadhethiya]

Sir can u copy past the programing in the descrption box so it will be easy

For pattern 11 and 12, instead of random(0, num_of_leds +1), can i just put random(0, num_of_leds)? without the '+1' as the number of led is already equal to 12 and the array myled[i] is only available for i=0 to i=11.

“Pattern11 was not declared in this scope”….. what to do?

[technicalsidhu]

Thank you sir....
Thank you very much sir

[naiksawan]

Hi nice work. More how many LED could be added?

[avinashpawase]

Which arduino that you used for this program? Nano Uno ??? Which one?

[justken]

what if i use a arduino nano ? it doesnt have the analog pins

[plasmaguy]

Great build can I use 8mm jumbo leds with this circuit? Joe

[OXFORD]

Hi. Why does the chase stop at the end and not loop to the start again? Many thanks

[Jords]

Can we program it into an another IC to use in an electronic circuit to run and how?

[magmagth]

Many thanks
I have a text file stored in sd memory as follows, it consists of three columns
0'10, 0
10, 0, 0
0, 0, 10
0, 0, 0
10, 0, 0
..
I have three LEDs connected to three terminals (pins) of the Arduino, for example 7, 8, 9

How do I get a code that enables the Arduino UNO to read the text file and convert each number 10 to 5 volts on one of the three pins
Thus, it will light three LEDs sequentially according to the data stored in the SD card memory. Thank you very much

Sir this video is super but the codeing is not clearly so you put the code clearly

[notuforever]

Bahi doubt intead connecting the the red Color we can give another colors aaa bhai

[sahitya]

Upload a video on blink a led for 5 min or more

[jeffwoodyart]

Arduino microcontrollers are not damaged when exceeding 200mA of voltage? 12 LEDs x 20mA = 240 mA load

[beef]

When it plays the last pattern it just stops, how can i make it loop back to the beginning? (I am a complete noob, only just bought one!) Thanks!

[ramzyamrouni]

How can we change the way of lightening of leds please. For exmpl 2 leds by leds. Or six leds by six leds

[puletshehla]

can you write this in Ladder Logic, for PLC?
