Good news, to use the Lambda Shield with Arduino Mega you need to reroute the SPI pins.
See example on our Instagram account.

Re: LEDs do not light
Hello,
Could you please take a picture of the set up. Refer to which software you are using. And what sensor you are using.
What is the serial output?
I think we can sort this out.
Thank you.

Lookup table for CJ125 in V=8 amplification.
I got a request for a lookup table when the CJ125 is in amplification V=8 compared to the standard code V=17. The V=8 mode is more useful for rich applications, the V=17 mode is more useful for lean applications. Here is a conversion table made from the LSU 4.9 data sheet for the V=8 mode: //Lambda ...

Re: Lambda GUI not reading
If anyone runs into the same symptom we have concluded that the problem in this case was a faulty oxygen sensor.

Re: Lambda GUI not reading
The readings are the same. I only experienced the flashing LED problem when I plug in the power jack but not the arduino. Thank you for clarifying. Using the multimeter, when reading ~1010 during operation could you please measure the voltage between the 5V pin and one of the GND pins on the Arduin...

Re: Lambda GUI not reading
And with the same issue do you mean that is reading 1010 ADC in open air or that it is resetting the Arduino and flashing the LED's?

Re: Lambda GUI not reading
If I try to plug in the power supply when the USB is not connected, the LEDs on both boards flash about once/second, but do not stay lit. I am not sure if this is normal behavior of the board. I can replicate what you are experiencing when I have the X7 jumper and the 12V power supply connected to ...

Re: Lambda GUI not reading
UA_Optimal (λ = 1.00): 304 (λ = 1.00) UR_Optimal: 176 These values are spot on, thank you. I'm concerned that the power source could be part of the problem. I'm using a 12V, 1A wall plug. However, it takes multiple tries of plugging the jack into the board, and removing and replacing the jumper wir...
