Arduino based VDI!

[Daren]

Hello,

i have upload the programm without errors. But the Dsplay shows only black cursors when i tune up the contrast. I have the LiquidCristal2IC library installed. I testet "LiquidCrystal Hello World" and it works perfect. Now i testet "LiquidCrystal2IC Hello world" and it shows only the black cursors after tune up contrast again. I think its the wrong Display. In the Sourcecode of the Arduino Vdi is mentioned to use LquidCrystal library not LiquidCrystal2IC library for other Displays. Can i change the Sourcecode that it works with my Display?

If all is wired correctly then maybe your LCD I2C device is at different I2C bus address. Use i2c-bus-scanner example to detect the I2C address. (googe: arduino i2c scanner),
For example see: http://todbot.com/blog/2009/11/29/i2...c-bus-scanner/
Each I2C device has factory designated address (sometimes you can change it with jumpers). You need to know yours. The code assumes most likely address (check the header with all the defines in the project), but your LCD can be configured differently. There is no standard for addresses.

I use classic 16pin connector. I have ordered two different I2C LCD's now. I will also do tests with the connectet LCD today ;-) Thank you guys! I will post pictures of the device when its finished and works without errors;-)

I got some inspiration from Daren's project and made some improvements to my own. Nothing besides an Arduino, 16 x 2 LCD and a handful of wires needed!! Plus the attached sketch. The only change needed to the IDX is to solder a pair of header pins and wires to U3 pins 1 & 14 and a ground wire from the IDX to the Arduino.

I added a fully functioning digital spectrum bargraph. Plus, with a concentric coil, accuracy is great.
Enjoy!

Thats amazing! Simple and accurate;-) Can you post how you connect the wires? I will test it on Tgsl. I have actually Darens version with an opamp working on my Tgsl.....but i want to test your version too on TGSL. I love simple solutions! Ok programming isnt simple for everyone;-). Thank you for sharing.

heres my Tgsl with Darens Version (Vdi wasnt finetuned in Video, actually its finetuned and is really accurate;-)):

The "Signagraph" seems to work very nicely. But ... I would suggest changing the name of your detector to something other than "A.S.S.".

I saw the YouTube videos, (I am informed by YouTube when you post new videos!) really good and stable. Also when actually searching as well?

Good work, thanks for sharing.

Here is my setup. I have included the pinouts in the sketch comments too.

Great stability, nice, simple code implementation. Its pretty crazy what you can nowadays achieve with few dollars of hardware and some code....

I know it;-) But its more about fun! My friends laughed too;-) It means Advanced Survey Systems.....dont take it too serious;-) Things that wouldnt work are for the ***...things that work great are Advanced Survey Systems;-)....its a hobby!

While waiting for parts from china I have been designing the plate in sprint layout. I would like someone to check if the plate is correct. Later I'll upload the file for everyone, now I need to know if everything is correct.

Seems fine.

[QUOTE=dfbowers;153092]I actually finished my IDX + Arduino UNO project. Below is the link for what the code in the previous post actually does. Neat thing is, you can program it to ID anything you want if you know the VDI range.

hello fellow, I liked the clip very good job! Can I ask you a favor? I will be very happy if you help me with one such file HEX. that they displayed different types of metal foil, zinc, silver, gold ........... I wish you success in the future.

Mission accomplished;-)! Thanks to all the guys who helped me (especially Daren). Im very proud of my new detector;-):

Very good Video, liked the music too.

Plus the detector is very impressive in both looks and performance with different metals.

How good is it with regards to depth? Both air and ground?

Many thanks for sharing.
