How can I get a 0-5V output signal compatible with YourDyno? Warning! Make sure you verify any signals before connecting it to sensitive equipment. Use at your own risk! http://support.bylund-automotive.com/analog_output/YourDyno.png The example code already have a PWM function to output an analog ...

Hi, I can understand the confusion. The problem is that the datasheets from Bosch tend to have less and less information about the functionality. They seem to go more for an overall description. However, I have saved the older versions for safe keeping which contain the information you need. Product...

From the DIY Wideband AFR Gauge on YouYube What is the value of the resistance in the capacitor? THANKS The RC-filter in the video uses a 220 µF capacitor. I believe the resistor was around 1.5 kΩ. I am sure you can tune it for faster response, I used parts available to me. Not sure if you are looki...

I was wondering if there was a way to simulate the lambda probe. Since i will be using a real probe with the lambda shield, i would really prefer if there was a way to cross check and verify that the lambda board is reading and reporting to the Microcontroller correctly without any gas or anything ...

One quick question, did you or someone else tried to connect Bosch 4.2 Lambda insted of 4.9? I have not seen the need, why use LSU 4.2 instead of LSU 4.9? http://bylund-automotive.com/images/CJ125.png According to the datasheet you need to configure the CJ125 by changing 2 resistors for it to work ...

I hope we can offer a wireless app very soon!

Hello Strgan, The simple answer is that you can not stack the Lambda Shield and Knock Shield on one Arduino UNO. The tricky answer is that you can probably connect the Knock Shield on the side using a breadboard, selecting the pins and functionality you require. It would definitely be possible using...

Hi George, I am no expert in chemistry but air does not hold more than 21% oxygen, starting from air might therefore not show any increase in oxygen. And considering that the environment need to be isolated and sealed from external influences it would be requiring a hermetically sealed enclosure fro...

I'm looking for an Arduino-compatible sensor for an Algae Scrubber project where I'm looking to measure the amount of O2 produced from the photosynthesis before the air exits to the atmosphere. Is this sensor something that can be used for such a project? If the oxygen content is higher than 21%, w...

Is it possible to implement an analog output for the Knock Shield? Yes, just like we did for the Lambda Shield . Here is how to connect the RC-filter to the Arduino. This is the RC-filter used in the example. To enable the output first we need to define the pin to be used. #define ANALOG_OUTPUT_PIN...
