Arduino LED light Control through Potentiometer

 

Here in this project we will combine two projects one is fading of LED light and second one is reading the analog value of pot-meter. Then resultant we will control the LED light with variation in the value of pot-meter.

Application:

We can control the speed of DC motor.

We can control the position of solenoid valve.

And some other related to this application

Calculation of factor:

A little bit calculation to manage the values of Analog read with PWM output.

Analog reading pin internally have 10bit of ADC so it means that

V_in (max) = 5v

Converted into 10bit digital means 0000000000 to 1111111111 from 0 to 1024

 2^10 = 1024

And PWM range is 0 to 255 so simple to fine the factor

Factor = 1024/255  = 4.0156 round off 4.02
