Hi everyone! I cant seem to find any tutorials on how to use the teensy 4.1 microSD so Im offering to make one for youtube if someone can help with the code.

The project will have the following:

Teensy 4.1
microsd card
2 x buttons (one wired to pin 7 and one wired to pin 8)
2 x resistors
1 x10k potentiometer.

The goal will be to read the value of the potentiometer and print it when the value is changed

Pressing the button wired to pin 7 will save the current value of the potentiometer to the SD card

Pressing the button wired to pin 8 will print the value saved to the sd card.


here is a schematic of what it'll look like (very simple)

Im horrible at coding but heres a starting point....
Code:
/* how to save to SSD Tutorial

   This example code is in the public domain.
*/

void setup() {                
   
  Serial.begin(38400);
  pinMode(7, INPUT);
  pinMode(8, INPUT);
}

int val = analogRead(A0);


void loop()                     
{


 int val = analogRead(A0); // reads the pot to see the current value


Serial.print("The value is: "); //prints the value of the pot
Serial.println(val);



  if (digitalRead(7) == HIGH) {              //if the button wired to pin 7 is pressed - save the value of the pot to the sd card
   Serial.println("value saved!!!!!!!!"); 
   
 }  

 
if (digitalRead(8) == HIGH) {  // if the button wired to pin 8 is pressed - print the value of the saved value
   
   Serial.print("the saved value is:");
    
  }  
  
 
   
  delay(250);

}
