Yes it looks like you can interface this with an arduino. It uses open collector outputs so you can directly connect an output to the Arduino's input if you enable the internal pull up resistor.

However I doubt you will find any tutorial giving you a step by step tutorial of how to do it is remote. It looks lie a complex device. Have you down loaded the Manual? It is a project that might be too hard for you to do alone.

Thank you for the respond grumpy_mike. I have download the manual, but I also really don't understand of all.
It's right grumpy_mike, this project too hard if I do alone cause this is a new that I never study before this.

link for manual:Redirect Notice

I very appreciate it.

G_M I think that's a coded request for you to partner the OP in this project :o

Seems the OP didn't search the forum, because although this thread started with the lament "I'm having an horrendous time trying to make the BV20 bill acceptor from Innovative Technologies work with Arduino", it has a happy ending.

I assumed he was talking about one of these :slight_smile: Now that would be an interesting project.

I have to search and try to understand from the forum..but I really don't understand the his flow

Hi,
In the top right hand corner of this page is "Search the Arduino Forum"
put BV20 in it and see what it finds.

Looks like most of the hardwork has been done.

Tom..... :slight_smile:

thanks for all

Hello,

I have done to connect my validator BV20 to arduino using the SIO (serial input output) interface.
I got it from arduino forum. Here the link:

http://forum.arduino.cc/index.php?topic=125119.0

void setup()
{
 Serial.begin(9600);
}

void loop()
{
 if( Serial.available() > 0)
 {    
   Serial.println(Serial.read()); // prints the result to Serial Monitor  
 }
}

and the result, I got it.

I insert 1 MYR,5 MYR AND 10 MYR. I set to my validator to accept 1 MYR and 5 MYR only. The others note will rejected from validator.

code for 1 MYR = 1
5 MYR = 3

You can see the code from the manual with SIO interface. Page 20 until 22
here the link: https:

So my question is how can arduino recognise the signal from the bill acceptor/validator BV20 SIO interface as input?

Hope can help me out.
Thank for advance
