Ok I have an arduino uno and a lcd 09066 which is 3.3 volt for the lcd and the arduino uno is 5 volt. My question can I use the LCD 09066 with the arduino or will I blow up the lcd?

Thanks Sean

I think you’ll need to put a level shifter between the Arduino serial out and the LCD serial in. The max voltage on a PIC 16LF88 input pin is 0.3V above the supply, which I believe is 3.3V. Connecting 5V TTL to the serial LCD won’t be good for it.
