Week Eight: OUTPUT DEVICES

I got very sick this week. so trying something new became very hard,

Goals

Leading up to mid-term review I aim to look at:
- charlie plexing: I would be curious to understand
- more complex sound - break out boards.
- I very much need to understand and catch up remote non-wired interactions.

Timetravel

Let's look at what output devices I played with previously.

I had mostly played with speakers and the amplifiers required for speakers.

this was my Kat-board: It was originally meant as just a breakoutboard board, with the paws like little add-ons that you could attach to your board.





This is was what i was using for amplification for 2023.





This is some of the code i tried running on it back in 2023

const int spPin = 5; //XIAO RP2040

void setup() {   
pinMode(spPin,OUTPUT);   
}

void loop() {
  //hz1000();
 toneOut(); 
 // pwmSound();
}

void hz1000(){
  digitalWrite(spPin, HIGH);
  delayMicroseconds(500);
  digitalWrite(spPin, LOW);
  delayMicroseconds(500);

}
void toneOut(){
//tone(pin, frequency, duration Usec)
  tone(spPin,261.626,1000000000);  //c4  
  delay(1000);
  tone(spPin,329.628,1000000000);  //E4
  delay(1000);
  tone(spPin,391.995,1000000000);  //G4
  delay(1000);
}

void pwmSound(){
  //analogWrite(spPin, 255);
 analogWrite(spPin, 150);    // low volume??
  delayMicroseconds(500);
  digitalWrite(spPin, 0);
  delayMicroseconds(500);
}
