December 8th Update

Our group met again today to test our final design project however it was unsuccessful. We did a lot of research and believe that the resistors that we used from our Arduino kits did not have the correct resistance. We believe that we need stronger resistors to allow for less current. We are going to try to get the correct resistors by Friday so we can present our project however, we are still happy with the work that we put into the project. Below is the video we took of our first attempt of using our paper keyboard.

December 2nd Update

After all of our hard work, it seems that our final project is almost ready to be put into action. The group is very proud of the work that we put into the design project and of the pre-final result. The following is the code that our group decided upon using to create our paper piano.

#include <CapacitiveSensor.h>
#define speaker 11
CapacitiveSensor   cs_2_3 = CapacitiveSensor(2,3);       
CapacitiveSensor   cs_2_4 = CapacitiveSensor(2,4);       
CapacitiveSensor   cs_2_5 = CapacitiveSensor(2,5);       
CapacitiveSensor   cs_2_6 = CapacitiveSensor(2,6);      
CapacitiveSensor   cs_2_7 = CapacitiveSensor(2,7);       
CapacitiveSensor   cs_2_8 = CapacitiveSensor(2,8);       
CapacitiveSensor   cs_2_9 = CapacitiveSensor(2,9);     

void setup()                   
{
  cs_2_3.set_CS_AutocaL_Millis(0xFFFFFFFF);    
 
 
  Serial.begin(9600);
}
void loop()                   
{

  long start = millis();
 
 
  long total1 =  cs_2_3.capacitiveSensor(60);
  long total2 =  cs_2_4.capacitiveSensor(60);
  long total3 =  cs_2_5.capacitiveSensor(60);
  long total4 =  cs_2_6.capacitiveSensor(60);
  long total5 =  cs_2_7.capacitiveSensor(60);
  long total6 =  cs_2_8.capacitiveSensor(60);
  long total7 =  cs_2_9.capacitiveSensor(60);
 

  Serial.print(millis() - start);       
  Serial.print("\t");                   
  Serial.print(total1);                 
  Serial.print("\t");                   
  Serial.print(total2);                 
  Serial.print("\t");                  
  Serial.print(total3);                
  Serial.print("\t");                   
  Serial.print(total4);                 
  Serial.print("\t");                   
  Serial.print(total5);                 
  Serial.print("\t");                   
  Serial.print(total6);                 
  Serial.print("\t");                   
  Serial.println(total7);               
                                        
 
  if (total1 > 150) tone(speaker,523);
  if (total2 > 150) tone(speaker,587);
  if (total3 > 150) tone(speaker,659);
  if (total4 > 150) tone(speaker,698);
  if (total5 > 150) tone(speaker,784);
  if (total6 > 150) tone(speaker,880);
  if (total7 > 150) tone(speaker,988);
 
 
  if (total1<=150  &  total2<=150  &  total3<=150 & total4<=150  &  total5<=150  &  total6<=150 &  total7<=150)
    noTone(speaker);
  delay(0);                             
}


This final code will be used to hopefully make our design as seen in the photo below work as desired!
