Hello, I am a newcomer to arduino and I too have been having a problem with this project. The first key (notes[0]) is the only one not working and this is after I made the change to the code suggested by mikeucfl.
void setup() {
buttons[0] = 2;
Serial.begin(9600);
}
Furthermore when I tried changing the ranges for the first two keys to see if I could get a wider range for the first key to play (1000-1023 for first key and 990-1000 for second), the second key instead played the note the first key was supposed to play and the first key was still silent (I got this idea from the fact that since the last key was near the highest value and had a small range of values to read the actual note would have a slight stutter when played, so I tried tweaking the range values). My breadboard is the same as the one in the manual. Does anyone have any suggestions for me? Thanks.
