Story

Like and Sub is appreciated.

In this project I converted Decimals to Binary with the Help of leds. I used 4 leds so maximum number of decimals I could represent was 15 but you can increase the number of leds and thus increase the decimal numbers represented using leds.I represented the decimals with the help of blinking in leds somewhat similar to morse code. Here is the representation of decimal numbers in leds:

I have given representation till 31 but since I am using 4 Leds I am limited to 15. You can increase the number of leds you use and therfeore be able to represent much bigger numbers.

In my leds he left-most was taken as pinkie and right-most as thumb. SO if I wanted to represent a number for example 12 I would lit up the pinkie and ring leds and dim the other two.

You can use any color of resistors.

I made this projects as I was trying to experiment the representation of words and numbers with leds. I also do not plan on making any projects for next wo weeks as I am in mid of exams and they carry half of my grade.
