Why this code not working as expected?

According to code, If + button is pressed the adc variable value should go upto 255 and stop. If decrement button is pressed it should go to min 0 and stop. adc variable is multiplied by 2 and written to POT. So, for 255 steps I should get 510 max adc value from channel 3. It is incrementing beyond range.

In your code, you have the variables adc and adcval? A mistake?

You read the a/d and stored the result to adcval, but used another variable adc in other sections in your code. :!:

adc variable is used for incrementing and decrementingc POT value. The POT o/p is fed to ADC input. ADC is read and assigned to adcval variable.


Problem solved. I had to use int type for adc variable.
