SSD1315 display;

void setup() {
    Wire.begin();
    display.begin();
    display.setRotation(1);      // rotate display 90 degrees
    display.setBrightness(0x7F); // medium brightness
    display.drawString(0, 0, "Hello", 5);
    display.display();
}

void loop() {
    // put the display to sleep to save power
