I'am new to Arduino, programing and posting. Trying to build a standalone flow meter. The .pde i downloaded uses a 16 x 2 LCD that i changed to a 20 x 4, I had on hand. It works, my problem is if I use the serial monitor or unpower the board i loose text and get garbage on the LCD. The only way to get the text back is to reload the sketch. Have the Arduino UNO R2 , attached schematic, data on LCD, and .sketch I changed for the 20 x4 LCD. Feel my problem is in programing or memory loss in the two counters. Any help appreciated and hope post OK with Mod's.
