0.96 Inch Display 128x64

OLED Driver IC: SSD1306

Resolution: 128 x 64

Visual Angle: >160°

Input Voltage: 3.3V ~ 6V

Compatible I/O Level: 3.3V, 5V

Mini Size: 2.7 x 2.8cm

Only Need 2 I/O Port to Control

Full Compatible Arduino, 51

Adafruit_SSD1306 the code is on Github. (May need to rename the library to import it without the _ )

Note: I2C address = 0x3C.

#include "Adafruit_SSD1306/Adafruit_SSD1306.h" /* ============== MAIN =====================*/ //Use I2C with OLED RESET pin on D4 #define OLED_RESET D4 Adafruit_SSD1306 oled(OLED_RESET); unsigned long previousMillis; unsigned long interval = 30000; void setup() { oled.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initialize with the I2C addr 0x3D (for the 128x64) // init done //oled.display(); // show splashscreen Time.zone(0); }

void loop() { oled.clearDisplay(); delay(200); oled.setTextSize(2); oled.setTextColor(WHITE); oled.setCursor(0,0); oled.print(Time.hourFormat12()); oled.print(":"); oled.print(Time.minute()); oled.print(":"); oled.print(Time.second()); oled.setTextColor(BLACK, WHITE); // 'inverted' text oled.display(); delay(800); }

Or you can use U8g2 graphics library or U8x8 for text only
