I am doing a project that needs some program tuning. The programable device is a Arduino Uno. I have a Temperature probe and a flow meter hooked up to digital inputs. I also have a LCD screen outputting info. I will attach all datasheets for each piece of hardware.
This is what I need:
*Temperature to output to LCD in Fahrenheit
*Flow device to trigger interrupt when water flows and start a counter/timmer on LCD
*Flow device to trigger interrupt when water flow stops and stop the counter/timmer
*Need to know if I have to have pull up resistors for the flow and temperature meters.
