DS1307

The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The 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 AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.

A Arduino RP2040 Standalone IoT Computer Running BASIC

“This instructable is about building standalone computers running a BASIC dialect suitable for IoT and interactive work. It uses low cost components that are readily available and can be integrated without much difficulty. So why running BASIC on a microcontroller …

Simple RGB Desktoclock using ATTINY85

“RGB Desktop clock using ATtiny85 and neopixel I wanted to make a customised clock for my desk. With the help of neopixel LEDs, I decided to build my own digital clock that is good enough to display the time while …

Arduino Science Clock

“I have toyed with the idea of building a clock for sometime and my sister had a big birthday coming up so I decided that this was a great opportunity to build a clock for her as a gift. My …

Folding Clock

“An interesting 3D printed clock that folds out flat or back on top of itself. Recently I build a Cube clock that showed the time in the same orientation no matter what orientation the clock itself was in. This was …

Cube Clock

“A tiny 8x8 matrix clock that automatically rotates the display when the cube is rotated. Recently I stubbled across the Lexon Flip Travel Reversible LCD Alarm Clock. It got me wondering about a clock that always showed the time in …

Lightning Detector

“It is often in the pursuit of one project that leads one to build others. For example, let us say that the work of Victor Frankenstein was being prepared for duplication at the premier Louisville, KY hackerspace; LVL1. Instead of …

Arduboy Pocket Watch!

“Ever wanted a pocket watch that you can play one click games on? Well then this is the project you were looking for! The first time I saw an Arduboy I immediately knew that I needed one, I also know …

Floating Water Quality Sensor

“The aim of this project is to determine the effect of climate change on river water quality. The turbidity of a river tend to change significantly during a period of heavy rainfall. Climate change causes shifts in the air and …
