Re: Lambda GUI not reading
My sensor is powered by a 1Amp, 12v wall power source, and the Arduino is powered with a USB connected to the computer. I believe I'm using the Windows App correctly - I upload the Arduino code to the Arduino, then open up the Windows App. When viewed in the Arduino Serial Monitor, the output looks ...

Re: Lambda GUI not reading
Yes, the output does not change at all when breathed on.
The Arduino file works just fine - but the values it reads while in open air are around 26%. This would make sense as to why the GUI isn’t outputting correctly.
Do you think the sensor is reading accurately? 26% seems very high for ambient air.

Re: Lambda GUI not reading
I'm now experiencing a very similar problem - it is stuck reading at 2.54 mA and 20.95% oxygen. These values do not change regardless of the actual O2 values.

Lambda GUI not reading
I've installed the Arduino GUI example and the Lambda Shield GUI program on my computer. When I run the standalone GUI program, it recognizes my board and accurately heats it up normally. However, it reads 0% oxygen and 0 amps. When I run the Arduino GUI example and open up the serial monitor, I can...
