I would need some advice and help, I am very new to the Arduino world, I am about to build a pulse induction metal detect from a kit, it uses pots for varies functions, I would like to use a liquid crystal screen and replace the pot with push button controlled with an Arduino and as the interface for the metal detector circuit board , either with an nano or uno . does anyone have ideas on how to get me started to accomplish this.
Well a link to your actual kit would help.
Look at the LCD example code in the IDE.
