I am using a 1K Pot connected on channel 0 of PIC16F877A to control the phase of the sine wave..
In Proteus its works fine.
I am using 1k POT but it is not showing exactly 1K value...
means value is varying randomly..
it is a 1K POT and sometime showing value around 2k or more than 2K but less than 3k
In my Hardware which i had made..
It gives me problem when i rotate the knob of POT... at some instant my controller stops working..
It gets halted.. I have used an LED which continuously blink when my hardware run..
And this LED glows always when i rotate the knob of My POT quickly..
Some times my Controller gets restarted...
I don't know whether my POT is causing my controller to restart..
I had disable Watch Dog Timer, Power On Reset and Brown Out Reset...
Any Advice..
Surely i am going to change my POT..
But will this fix the Problem..
I have to submit my hardware tomorrow..
So needs help..
Thanks in Advance
