Arduino based VDI!

Connection

i2c connection...

For Arduino board, ofcourse it can be used Nano, Micro, Mega, etc... On this picture Uno is used as example, connection pins are the same for all of them, personaly i'm using nano cause fits nice to my case.

OLED setup

Here is, also there is a connection on the picture for i2c setup. For sensors u need to to connect A0 and A1 pins to pin 1 and pin 14 to (U3) LF347. One of the most important thing is that the machine and Arduino board need to use separate battery.

Did you finish it? cdi

Well done CDI!

Looking good!

Thank's man, i will post setup and code soon...

Nice, nice really nice!

Here is my new Arduino vdi project with small 128x64 display. Implemented bargraph and custom font's. Machine on the photo is IDX with 12.5 inch coil. Soon i will upload short video...

Thanks Hyena! That helps give some explanation.

Hey Everyone,

I decided to build the VDI that Daren has made, I like the extra options that it offers. However I'm not quite sure what the MCP602 is supposed do. For the MD_V13 there is an included read me file that doesn't mention that the MCP602 is required, but the included schematic shows the MCP602 in there.

Daren mentions MCP602 in post #69 http://www.geotech1.com/forums/showt...684#post193684



I ordered a few MCP602's because I want to build the VDI correctly but, What specifically does MCP602 do in his VDI?

Thanks!

Because Arduino can read 0-5V and input is -6 up to 8V?

Also batery reading is voltage divider to rescale 0- >12V to 0-5V.

I use LM358 single-side powered with 0 and 5V. It swings 0-4 on output. Circuit is like the one for IDX-VDI minus balancing resistors (R9, RT2 i think).
Seems to work fine.
Arduino Mini Pro 16MHz, 5V with LCD (dimmed with 1K) and opamp takes 12V/25mA. Arduino is powered using TGSL's 12V and it suppliers 5V for the opamp (mini has a 5v regulator). I'll swap in MCP602 when it comes from china; it should have 0-5V output swing.

Maybe a PDF would be good.

You can also download free version of eagle from Autodesk which will be fine for viewing.

Do you have a picture file ?, not everybody is going to have Eagle8 program.
