Internet Clock: Display Date and Time on OLED using ESP8266 NodeMCU with NTP RTC or Real Time Clock is the most commonly used module in Electronics and embedded devices to keep track of time. But the problem with RTC is that the microchips in computers are not that much accurate and they can only provide the time of local device. On the other hand, using the internet to fetch the time from NTP servers is better solution for getting time as it is more… |

Interfacing OLED Display with NodeMCU ESP8266: Displaying Bitmap image on OLED In this tutorial we will interface OLED Display with NodeMCU ESP8266. NodeMCU is an open source IoT platform that includes firmware which runs on the low cost Wi-Fi enabled ESP8266 Wi-Fi SoC from Espressif Systems. It has GPIO pins for connecting other peripherals and it supports serial communication using SPI, I2C and UART pins. It also has pins for ADC and PWM. We… |

Build a Smart Watch by Interfacing OLED Display with Android Phone using Arduino Most of us would be familiar with the 16×2 Dot matrix LCD display that is used in many projects to display some information to the user. But these LCD displays have a lot of limitation in what they can do. In this tutorial, we will use OLED to display some basic information from the Android smartphone like Time, date, network strength and battery status… |

Internet Clock using ESP32 and OLED Display In the previous tutorial, we have made RTC clock using DS3231 and ESP32. To minimize hardware requirements we will make Internet clock without using RTC module. This is more accurate as compare to RTC clock. ESP32 is a Wi-Fi module and can be easily connected to the internet so we will use NTP (Network Time Protocol) and UDP (User Datagram Protocol) to fetch Time from the… |

ESP32 Real Time Clock using DS3231 Module In this tutorial, we will learn about Real Time Clock (RTC) and its interfacing with the ESP32 and OLED display. We will use the DS3231 RTC module to keep track of the correct time and display it on the SPI OLED by using ESP32 as our microcontroller. ESP32 is more than a microcontroller. It has a Wi-Fi and Bluetooth chip inside it and 39 GPIO pins.… |

Interfacing SSD1306 OLED Display with Raspberry PiMost of us would be familiar with the 16×2 Dot matrix LCD display that is used in most of the projects to display some information to the user. But these LCD displays have a lot of limitations. In this tutorial, we are going to learn about OLED display and how to use them with Raspberry Pi. There are lots of types of OLED displays available in the market and there are lots of… |

OLED Display, its Types and Working To start with let us understand what these OLED displays mean. The term OLED stands for “Organic Light emitting diode” it uses the same technology that is used in most of our televisions but has fewer pixels compared to them. It is real fun to have these cool looking display modules to be interfaced with the Microcontrollers since it will make our projects look cool.… |

Understanding OLED Display Technology Let’s dream about a high definition television that is even less than a quarter inch thick, curved and about 80 inches wide. Moreover, it consumes lesser power than your normal TV set and it can be rolled up if you don’t want to use it. You can also carry that TV around wherever you like. What if we could have a display monitor inbuilt in our clothing? Does it look real or… |
