So i am very new to all electronics and Arduino projects. Very Very new.
I cant figure out how to get the Certamen message to come on to the LCD screen after following the instructions on:
These specific instructions:
Make sure you have the Arduino IDE installed. Download my software from here. You can just download the zip file and put its contents into the Arduino directory.
Inside the zip file, you will find another zip file, called ModNewLiquidCrystal.zip. This is a little tricky to deal with. It's a highly optimized library for dealing with the 1602 LCD, and it will improve the timing precision of the Certamen device. Delete the default LiquidCrystal Arduino library. (On Windows, it's in C:\Program Files (x86)\Arduino\libraries .) Then extract the contents of ModNewLiquidCrystal.zip into your Arduino user libraries folder.
Connect the Arduino to the computer, set Tools | Board | Arduino Mega ... 2560, Tools | Processor | ATmega2560, and Tools | Port to your Arduino's serial port (hopefully there is only there). Then upload with the right-arrow button.
If all is well, the LCD will show a Certamen message, and go to a screen that just says "Certamen". If not, something is wrong with your LCD connections. If the contrast is bad, you might swap out the 2.2K resistor for something else. Or use a 10K potentiometer, as here
Thank you for any help
