    Hi again, I was asking you questions before about getting the program uploaded and the Certamen message to show up on the LCD. I finally got that to work. Thank youSo now i am a bit further along. I have the all of the wiring done (the arduino to the stripboard and the buttons) the problem that is occuring now is that the lcd is showing button presses when there is none. I do not have the daisy chain of buttons plugged into the rj45 sockets when this is happening. For example as soon as the certamen message goes away A4, B2, C3 pop up (or any other combination of buttons). I press the clear button and immediatley they pop back up. I also mess with the toggle switch and then just one button press will pop up, but none the less still shows upThe obvious answer is bad solders or wiring i f...

    So I got Certamen to come across the the LCD screen. I did what you said in your last reply.Then in the Arduino environment I went to "File" then "Sketchbook" and "certamen" came up. Then i clicked that and uploaded. Thank you. I might have questions further on

    I deleted the LiquidCrystal.h as directed in your instructable. You can look at the these pictures from left to right (1 thru 6) to see the file paths i take to get to the arduino environment that looks the same as your picture on the instructable.Also on the final two pictures is where i got your software. I selected "clone or download" and went from there. Just curious if that is where a possible mess up happened?

    This is where i am at now.As you can see from the first picture, the Arduino environment has all of the same tabs at the top as yours does on your instructable. The error shown is what i am now getting.The second picture is how i am testing it. Just with a bread board and the connections needed for the lcd and arduino. I do have the strip board with all of its connections made (see picture 3), but did not think it was necessary to test with it since in your instructions you say that you can connect it later to further test it. I am really at a loss with what to do. I do not believe that my problem is with any of the connections, but somewhere with the Arduino environment and uploading the codes. Thank you.
