Hi All!
I am developing an academic project that consists in using an Adafruit Wave Shield along with an Arduino Uno.
The purpose is to decode Braille into voice.
I have 6 switches, each one representing one of the 6 dots that makes a Braille character.
Summing up, we select the switches that will be on (or off) and after thar we click one last wsitch that gives the order for the proper audio file (with the correspondent letter) to be played.
Please note that the if cycles are not yet on the code.
My only issue is that after inserting the parts relating the waveshield in the code, the buttonPin7 just stops working. If I remove those parts, it works perfectly.
Any ideas?
In attachment you have the a.txt file with the non working button7
and the b.txt with the working witch buit without the audio part
