i got this project

You are required to design a project that creates a fully ‘black’ square customised LCD character – as the POTENTIOMETER is turned the top line of the LCD module starts to fill with these characters to form a bar-type display – fully advancing the POTENTIOMETER will fill the tope line with 8 such characters whilst fully reducing the POTENTIOMETER will result in no characters displayed

Hi yoyomin, can you share with us the averaging filter that you used. You have got stable readings.

My name is Todor and i am from that my english is very badd (excuse me for that) I learning for Engineer and i saw your project. It was awesome.. good for you.. Can i ask you and please you to send me a program code and schematic for this wonderful project.. I really wanna do it for my School Project this ear :).
My email is :
Skype is: hacker4eto1
I really thank you ,and good for is awasome..

As far as I remember there was an averaging filter which makes the reading stable.

Author Dan Frederiksen ( ago)
how can there be that many decimals and that stable?
what bit depth is the ADC?

Hello sir,
thank you for your prompt response
I am a beginner and would like to learn how peak
here is my email address:
good you to men.
at the nex time

Author yoyomin ( ago)
Salut! Yes I have the code. If you leave me your email I could send you the files. They are written in PICC. For the schematic please refer to HD44780 datasheet and the datasheet of your microcontroller.
