- How to output 0-1V with your Arduino. We connect a gauge to the Lambda Shield and make a DYI lambda gauge.

Neat. I might have to look into doing something DIY, I don't feel like paying for an expensive gauge and controller that I don't like looking at. Buying things isn't my style so I might have to make my own arduino with something like this built in instead of a shield.
software contrrolled PWM PLUS passive components, or 2 resistors for a voltage divider. Which makes more sense?
So you are only simulating the narrowband 0-1v signal. But the board puts out analong 0-5V correct? I want to use this in condjunction with my speeduino.. but im getting confused. Is this a narrowband controller or wideband? Thanks
It is a wideband controller simulating the signal in this video for a narrowband gauge (0-1V). You can configure it to output any wideband 0-5V signal.
Can this be done with an arduino nano ?
Could I output my data to a typical 16x2 I2C LCD? All my gauges in this project I'm doing uses a bunch of 16x2 LCD's.
Yes! Have you watched our video about display output? th-cam.com/video/BooPunk9URI/w-d-xo.html
I this something I can do I have zero experience with with code but my friend has his Computer science degree so should I try and then ask for help?
All the code is readily available on our website. If you need help we have a support community. community.bylund-automotive.com
what is the value of the resistance in the capacitor? THANKS
Hi Adrian. 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 looking for the ESR?
@@bylundautomotive A question The resistor is located on the green wire or the black wire?
@@adrianadrian615 The green wire in the video is connected to the resistor in series. Red is 12V to power the gauge. Black is ground. I made a post about this on our website if you want to see a schematic. community.bylund-automotive.com/viewtopic.php?f=8&t=2211
if ineed an 5v source what shoul i do
Interesting. May I buy it from you please? I am from Malaysia
Yes, we ship worldwide. You can order from our website, www.bylund-automotive.com
@@bylundautomotive Thank you sir. But I wondering, the board already set for wideband gauge or I have to set it by myself?
The code is already prepared for 0-1V analog output the only thing you need to do is add the RC components as described in the video.
@@bylundautomotive The RC components will convert 0-1v to 0-5v? Or will make the narrowband gauge can read the signal from wideband O² sensor?
@@gilakail The Arduino will output a 5V PWM signal, the RC-filter (Resistor and Capacitor) will make it in to a 0-1V DC-voltage output. The narrowband gauges require a 0-1V DC signal to imitate a narrowband sensor but the display will be wideband.
Merhabalar bu göstergeye wideband 4.9 Lsu sensör bağlayabilir miyiz?
Yes! The Lambda Shields are for Bosch LSU 4.9 wideband sensors.
Infortunately, this is too pricey for a DIY solution. Even Spartan controllers are cheaper.
We are constantly working on improving the price, currently we are very close to the Spartan controller at 75 USD vs the Lambda Shield 2 at 65 EUR excluding the cost of the Arduino.
0-1v is not wideband.
It is wideband, the 0-1V is required to match the input range of the gauge. Narrowband = rich or lean, wideband = how rich or lean. Perhaps you are confusing it with narrowband sensors outputing 0-1V?
@@maximexc1299 Maxime, are you referring to 20$ narrowband sensors like the 3 wire ones, or 20$ counterfeit wideband 6 wire ones? Original wideband Bosch LSU 4.9 typically cost 100$-150$ including VAT. The problem we have seen repeatedly with the counterfeit sensors from China is that the heater feedback to the lambda controller is not working properly which is why we do not recommend them, that being said this may not be everyones experience.
@@bylundautomotive Thank u
it is wideband, the controller convert wideband signal to 0-1v + RC filter (Narrowband simulation) so that can be read by narrowband afr gauge. The narrow band signal always fluctuate from 0-1v.
DIY? BS.
