Re: Lambdashield 2

Is there a reason why you removed the Pin-Bypass in the new Shield? Even though you have the full pinout, most pins are in use which makes it unusable with any stacked shield. Instead Lambda Shield 2 can be used with Arduino Mega 2560 giving plenty of additional pins for expansion. You can still pu...

Re: Lambdashield 2

Hello Maxburn, Is there a detailed circuit diagram of the Lambda shield 2? Schematics is available on the product website . I don't understand e.g. why the shield uses the ICSP ports and why the shield does not output the whole pins reusable on top. Some Arduino boards only have access to SPI pins t...

Re: Car battery

Hi Christian, i plan to use the lambda shield in my old car to measure the air/fuel ratio for adjusting my carburetors. My question is now can i attach the board directly to the car battery? And is there something i have to take care of? Cheers Hello, No problem, just connect the battery to the lam...

Re: App freezes

I have reset the Adruino and updated it again, and uploaded the code again. When I connected the arduino I had a signal almost directly and it look liked it didnt froze but I need to drive my bike to say for sure. But I think the problem is solved. Great, problem solved? I got a realme 7 pro with A...

Re: Pins remaining for Serial Tranmission

Hello Arch, Pins D11 and D12 are reserved for SPI communication on any Arduino (MISO and MOSI). SPI is required for the Lambda Shield 2. You can use the standard Serial hardware interface RX (D0) and TX (D1) pins for serial communication on the Arduino Uno / Mega versions. On Arduino Mega you have 3...

Re: App freezes

Hello Wiebel,

Lets figure out what the problem is.

1. Have you updated the Nina firmware on the Arduino Uno Wifi? See the troubleshooting section.
2. What phone and OS version are you using?

Thank you.

Re: How to improve knock detection?

Hello! It was easy to do because your manual is very good. Thank you, it seems you have understood it very good! Question 1: Does this look correct? I'm a little surprised that results aren't consistent between both sensors. On this V8 they are mounted on the outside of the iron block, one on each s...

Re: Arduino I/o pin useage

Another simple question - I just received my shield, and I noticed there are not sockets at the top of the board to connect the interface wires to the display you demonstrate in your YouTube video. Is the code & display compatible with the lambda shield 2 version I have? Is it as simple as just...

Re: Bluetooth connection

How did youget your smarthpone-connection with 1.2.2 running? With this old lib-version i´m unable to connect to the device (but found in scan) neither with a simple example code. 1.3.4 works everything fine but then the example size is ~1KB too big to upload. Hi! Simply upload the Lambda Shield 2 ...
