hello, sorry i tried to read data from arduino to processing ide 4.0.1 but am getting wrong last value on the gauge in display window of processing ide i don't know why it happen that, other 5 values that am getting are fine but the last 6 value is wrong. below is the full processing ide code.

// Import Meter library
import meter.*;

// Import serial library
import processing.serial.*;

// serial port buttons

any help please

TomGeorge · September 17, 2022, 8:28am

Hi,
What model Arduino are you using?

What value is tankval6l value and what does processing display?
Is the misread constant or are you getting random readings for a steady value of tankval6?

Thanks.. Tom..

mwanyamaki96 · September 17, 2022, 9:14am

am using arduino nano, am reading that value through analog 5 port am getting random values

paulpaulson · September 17, 2022, 9:47am

Hello

Post a schematic to see how we can help.

toddnz · September 17, 2022, 9:51am

Just a quick thought, did you try swapping tank6 with another, working tank? Would give you an idea of whether the issue is with software or with hardware / the tank sensors.

mwanyamaki96 · September 17, 2022, 10:07am

i have resolved the problem thank you all

UKHeliBob · September 17, 2022, 11:09am

What was the problem ?

mwanyamaki96 · September 17, 2022, 2:02pm

it was on the hardware side.

TomGeorge · September 17, 2022, 2:49pm

What was the hardware problem?
