Things used in this project

Hardware components

Resistor 1k ohm

Those who are using four pushbutton , they will need four resistors . Those who are using one touch sensor , will only need three.

SparkFun Pushbutton switch 12mm

Touch sensor

optional for one push button.

Jumper wires (generic)

Arduino UNO

Software apps and online services

Arduino IDE

Arduino Web Editor

optional

Story

First of all, I was just tinkering with led's and arduino. Then, a idea strike up my mind and I decided to add buttons to led's to change the various patterns in led's. Here is what I got as a result -

This will be the result !!

Well, I did not have four pushbuttons, so I had to use one touch sensor. For touch sensor, in the code, I did not write any different code. Same as the code for the three pushbutton. Hope, fully, it worked !!

To make it cool, I did not use led ' s of same colour, but used blue and green led's in the sequence green, blue, green, blue.....

I am a begginer and I could not make the code short. (sorry for that).

For those who do not have touch sensor also, I am trying for them with one push button.

Well , instead of one pushbutton , i am using touchsensor because i have bought a starter kit and most of the starter kit include the touch sensor.

The result.
