Lcd Not Working..

Hi Dwayne

Thank you very much I will try everything you've said.

PS:I have not connected my pot to the 8v, but to the 5v output side.

Did you check the pinning? As far as i can see it uses a different pinning than normal. Also the fact that your powersupply drops imply that there is a wrong connection somewhere.

Hi Ingvar

Thank you I will double check it and see if I could find the problem.

The only difference that I can see is Pin 1 on the HD44780 is now pin 14 and every pin just shifts up.
