Use Meadow. Foundation to quickly and easily wire up a LCD screen and a RTC module to make a Christmas countdown display.
Out of the M5Stack family only the M5StickC has an inbuilt RTC. Here's how to add one to your other M5Stack devices
Clock without using RTC in Arduino with Temperature and humidity indicator
Create an OLED screen that shows the date, time in digital and analog format, temperature and humidity.
Make a 7 Segment digital clock with MAX7219 and DS1307 Real Time Clock (RTC) - Quick and Easy!
This alarm clock and timer work without the help of a computer. All the settings can be done on the clock itself and stored in the EEPROM.
I made a complete example for anyone else out there who wants to use the LinkIt’s onboard RTC.
The O-Watch Simple Watch code tweaked to use the Arduino Zero's built-in RTC, plus a couple other tweaks.
Flip Dot Clock is a clock using Flip Dot Display. It's a matrix of colorful dots flipped by electromagnet, not LED.
Another type of clock, which needs a bit of thinking, before you can read it...
Connect DS1302 Real Time Clock to Arduino Nano, and program it - quick and easy!
Most hygrometer sensors are known for quickly corroding. This project takes advantage of a RTC to trigger the watering for a herbal garden.
This is an alarm for your house that rings when a movement is detected, like when the door is open or when a body walks in front of it.
Never forget to turn ON/OFF your aquarium lights.
Remember the days when you would sit listening to WWV time signals on your shortwave radio (tick, tick, tick…At the tone, the time will be…)
This project demonstrates the use of electronics and embedded system with clock.
A simple Arduino-based temperature data logger
Arduino-controlled Christmas Tree lit by 150 digital RGB LED pixels. The RTC chip switches on and off the tree at the planned hours!
Using 128×64 monochrome display with ST7920, I made an adjusting RTC clock based on an Arduino board.
A compact air quality, temperature and humidity monitor enclosed in a small wooden chest, with a four-row LCD display.
A tutorial of building a web clock with only an ESP8266/ESP-12 board and an SSD1306 OLED display by using built-in modules of MicroPython.
Example of how to use the ESP32 with the RTC DS3231 module for accurate time keeping.
Ever wanted to make a project that activated on a schedule? Using a Real Time Clock (RTC) is a great way to do it!
I fixed the lack of a retentive clock in Raspberry PI with an RTC (DS3231 I2C real time clock) and POWER-KI, under Windows IOT.
