ESP32 with a DHT22 temperature sensor, show readings on a 0.96" OLED every 2 seconds

// DHT22 on GPIO4, OLED on I2C
DHT dht(4, DHT22);
Adafruit_SSD1306 display(128, 64);

void setup() {
  dht.begin();
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
}

void loop() {
  float t = dht.readTemperature();
  display.clearDisplay();
  display.setCursor(0, 0);
  display.printf("Temp: %.1f C", t);
  display.display();
  delay(2000);
