Hi
I need to make a Winbond 1740 voice recording kit ( which I already have ) react to a BCD number from 1 to 9 ( parallel 4 pins ) .
The kit has a SPI connector.
There is a momentary valid transmission from the ( Holtek HT12D ) decoder chip when it receives a number from one of 9 checkout points, ( along with the 4 data bits representing the BCD number for the checkout.)
I need the voice chip to announce which checkout is calling ( I have a visual indicator of the number but need voice too )
I have found quite a few older postings when I search for Winbond in the forum, but I think this might be way too complicated for me, unless there is a library somewhere that I can call up .
I am a newbie ( I got my Arduino 3 weeks ago ) and have only made one project so far, a simple cnc machine using the AFmotor library, and the mechanism stripped from a flatbed plotter, which was very satisfying.
Can anyone recall a similar voice project that I can modify?
