pwm using adc

hello everyone.. i need help for ADC and PWM.. right now i have done everyting.. but how to write a code to when ADC reading the value and PWM change.. i have done ADC and PWM but how we control the voltage?
 

reading pwm with adc

Why do you keep starting new threads on the same subject. Why not just continue your original posts?
 

read pwm adc reading

because no people replying mi.// sad
 

Re: ADC n PWM

You have done every thing.
You have done ADC and PWM.
No need to worry, sit aside or just write down the code if you need. May be you would like to test and try the same.
 

ADC n PWM

jason1987 Just give it a little thought, it all depends on what language your writing it in, If your using the 10bit A/D then you need to scale it down unless your using 10bit PWM, Read the the votlage coming in then just make the A/D raw value into the PWM variable, Do do it by a push button the read button then just increse the PWM value

Or why not post your code and say this is what I have done but it does not quite work then may be someone will be willing to help,

Re: ADC n PWM

erm my code actually very simple.. i have done most of the ting...mine ADC is 8 bit.. now i am doing another button to dim the LED... another led i program as brightess as in percent go up cannot go down

@wizpic,
you are a nice person and I think your recommendation is just right, unfortunately way over Jason's head ;-)
The "give it a little thought" part seems to be missing completely in his posts.
