#include <Wire.h>
#include <i2cdetect.h>

void setup() {
  // The Oled screen won't be visible unless we set the RESET line on the screen high
  pinMode (16, OUTPUT);
  digitalWrite (16, HIGH); // while OLED is running, GPIO16 must go high
  
  // Rather than 
  Wire.begin(4, 15);
  Serial.begin(9600);

  Serial.print("Scanning address range 0x03-0x77\n\n");
}

void loop() {
