Creating a Fritzing Diagram of an Arduino Glucose Meter

Question

Hello Everyone!

I am new to the tinkering community and faced a challenge trying to reproduce this rather simply looking Arduino Glucose Meter made of a stack of:

Arduino UNO
Li-Po (Lithium Polymer) power shield
Preprocessing Circuit Soldered on the Arduino Proto Shield with a LMC648IN Quad Op-Amplifier

I have purchased all the items to attempt the project however it is not very clear which components were used and how exactly each connections was made and would like a simple Fritzing Schematic diagram from any expert here so that I can complete my project

This is the blog detailing how the author put the items together:

And a 1-minute video of how it works:

Thanks!

Hello George, The link you provided doesn't give all of the information normally provided in an instructional blog. The video seems more promotional than informative but a schematic is flashed up about 20 seconds in. I can't recommend Fritzing, it is best to learn how to read a schematic. If it were me building the project I might contact the author and see if they are willing to provide more information. If not, you can attempt building it from the schematic in the video.

Try building it on the breadboard first by connecting the components with jumpers per the schematic described in my post below. You can arrange the components on the breadboard in a similar way to the original authors photo. When it is working, transfer to the shield and solder it up. If there are problems with the breadboard make another post and solicit help debugging...

Thanks a bunch for reaching out Mike!

I found the actual Proto Shield that was used on top of the stack:

(Includes a 10K potentiometer, 1K potentiometer, 2 small pushbuttons, 5 red diffused bright LEDs, one each of red, green and blue ultra-bright LED, 5 100 ohm resistors, 5 1K resistors and 5 10K resistors.)

And the Operational Amplifier :

Maybe that could be of some help to decipher what is going on or tag anyone on this community who has a clue what is going on.
