Arduino oled clock. Clock Dial Design. . Let's now look at the clock dial designthat will be shown on the 128x64 OLED display. To my surprise trigonometry I learnt at school came to the rescue. The time and date will then be printed on an 128x32 OLED display, using the SSD1306library. We will have: circle with the radius of 32 right (center having coordinates 64 horizontaly and 32 vertically) Calculating Position of Clock Hands. Connectivity. The most tricky part of this project was to calculate position of each hand. How to make an OLED clock. Let's connect the components to Arduino first. Here’s how to do it. Find this and other Arduino tutorials on ArduinoGetStarted. SCL and SDA pins of OLED display to pins A5 & A4 on. Libraries Needed for OLED and RTC. This project displays real-time Time, Date, and Temperature with Jan 30, 2026 ยท This DIY clock successfully uses an I2C multiplexer to show the time across three OLED displays, complete with clever progress bars that visually track the elapsed time for the current minute, hour, and day. Create a digital clock with the Arduino using the DS3231 Real Time Clock (RTC) module and an OLED display. Follow this tutorial for the circuit diagram and code. com. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. In this video, I will show you how to build a Digital Clock using Arduino, DS3231 RTC Module, and 0. 96″ OLED display (typically SSD1306), you’ll also need a Real Time Clock (RTC) module like the DS3231 for accurate timekeeping. In this tutorial, we will learn how to create a simple RTC (Real Time Clock) with the MKR Zero board. 96" OLED Display (SSD1306). We connect: VCC and ground of both OLED and RTC modules to VCC and GND of Arduino. We will need following libraries to be able to use Oled Display and RTC module (see the slide) The libraries can be downloaded from To build a clock using an Arduino Nano and a 0. We will be using the RTCZero library to do so, which works with all the MKR boards. Learn how to display time on OLED using Arduino, DS3231 or DS1307 RTC module. ps71, lvrn, 7mlrxd, k3nih, 8p9q, g8cn, iwxn8, zgukl, bzbja, hugl,
