attiny85 code to print to usb keyboard the analog value at adc1 (p2); also outputs 1 on the GPIO p1 when below 300 (and lighting the LED)

ptt.ino

#include "DigiKeyboard.h"
#define ADC1_P2 1

void setup() {
  pinMode(1, OUTPUT);
}


void loop() {
  char output[32];
  int analog;
  
  DigiKeyboard.sendKeyStroke(0);
  analog = analogRead(ADC1_P2);
  digitalWrite(1, analog < 300 ? HIGH : LOW);
  snprintf(output, sizeof(output), "%d\n", analog);
  DigiKeyboard.println(output);
  DigiKeyboard.delay(500);
}
