Well after much heartburn (and once again being burned by pull down resistors). I have managed to make some progress.
I now have half of my Music Glove prototype complete. This is the hardware side. I paired a bluetooth module from sparkfun (something that does uart). With an arduino to handle the button presses. I can now receive an A and a B from my button presses on my phone using the BlueTerm application.
Once I am able to handle receiving the bluetooth data on the phone side, I will better package the whole assembly.
Here is a shot of the circuit:
Here is the code which does all the work:
/*
What you will need to do is wire up your bluetooth module hooking the RX and TX up to the arduino, then
*/
// A is IO 2
int A = 2; // Switch connected to digital pin 2
int AState = 0; // Switch connected to digital pin 2
int AStatePrev = 0; // Switch connected to digital pin 2
// B is IO 3
int B = 3; // Switch connected to digital pin 3
int BState = 0; // Switch connected to digital pin 3
int BStatePrev = 0; // Switch connected to digital pin 3
int buttonState = 0;
void setup() // run once, when the sketch starts
{
Serial.begin(115200); // set up Serial library at 115200 bps
pinMode(A, INPUT); // sets the digital pin as input to read switch
pinMode(B, INPUT); // sets the digital pin as input to read switch
}
void loop() // run over and over again
{
AStatePrev = digitalRead(A); // Switch connected to digital pin 2
BStatePrev = digitalRead(B); // Switch connected to digital pin 3
delay(60);
BState = digitalRead(B); // Switch connected to digital pin 3
AState = digitalRead(A); // Switch connected to digital pin 2
// Handle button "2" presses
if (BStatePrev==BState)
{
if (BState == HIGH)
{
Serial.println("B");
delay(60);
}
}
// Handle button "1" presses
if (AStatePrev==AState)
{
if (AState == HIGH)
{
Serial.println("A");
delay(60);
}
}
}
