DS1302

The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial communication. Only three wires are required to communicate with the clock/RAM: CE, I/O (data line), and SCLK (serial clock). Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1µW.

A Circular Binary Clock

“In a previous instructable, I have presented a concept for making a “linear” binary clock from a standard WS2812 LED strip and an ATtiny microprocessor. The design of that clock was not that great… …which is why I made a …

Analog Style Arduino OLED Clock

“This is a tutorial how to show you how to create analog style clock using Arduino and a small OLED display. There is also a video version of this tutorial. You will find the link at the end of this …

Clock with SH1106 OLED display & DS1302 RTC module

“A short, simple project about a clock made with an Organic LED display and DS1302 RTC clock module, for ex. to use in full-screen game… Supplies: - Arduino UNO board clone (you can use the original one, I’mtoopoor). - DS1302 RTC …

Raspberry Pi Pico - Alarm Clock

“Hello everyone, do you have a Raspberry Pi Pico and want to build an alarm clock and need some guidance on getting started? If so, this instructable is for you. This project is a straightforward alarm clock based on the …

FM Radio with Clock Function

“Clock radio using the RDA5807M and RTC DS1302 I liked the original radio design and use of the miniature RDA5807M Stereo radio module and decided to modify the code and add a clock to the design. After trying to use …

World Alarm Clock

“This small battery powered clock can be configured to display as a analog clock, digital clock, world clock or as a digital alarm clock. This clock is similar to the Nokia Analog Digital Alarm Clock that I built a few …

Project  Ljinux

Ljinux

“A “linux” written in python, for the Raspberry Pi Pico. Important note: Do not take this project seriously. I know it’s not a linux, or an os, or anything in that regard, but here we are. Anyways, since you …

Piano Metronome

“This project was conceived of after I examined the types and styles of various off-the-shelf Metronomes. I am currently learning to play the piano and having a Metronome in order to keep time was necessary. I felt sure that I …

Tiny Word Clock

“A 3D printed tiny word clock build using a 8x8 LED matrix and ATtiny1614 microprocessor. Story Back in 2017, I built a large Word Clock designed by wabbitguy. Recently I came across a word clock based on a 8x8 Matrix …

Connect LCDs With NodeMCU and Arduino

“Most of our Arduino projects require a way to present us with information about their state, and very often an LED can be enough to indicate if a condition is true or false. But, it is not uncommon that we …
