This post is about how to use the DS1307 Real Time Clock (RTC) module with the Arduino. You can also follow this guide for other similar modules like the DS3231 RTC. Introducing the Real Time Clock module The r
I have found that the use of the RTC chip- DS3231 is extremely hard using the arduino. Just setting the time is pretty complex, not mentioning the code. Therefore I have found a great and easy to use library which really enhances the use of the DS3231 chip. Let's get right onto it...
I've been working on a Raspberry Pi Pico project that I wanted to run off batteries. I found a "low power" example in the pico-extras which uses the Real Time Clock to wake the device up after an interval. So I set about porting it to the Arduino platfor
Adafruit PiRTC - PCF8523 Real Time Clock for Raspberry Pi $7.50 Add to Cart CR1220 12mm Diameter - 3V Lithium Coin Cell Battery Out of Stock 38 Beginner Product guide RTC with Arduino Wiring Wiring it up is easy, connect it up as shown below. ...
In this Arduino Tutorial we will learn how to use the DS3231 Real Time Clock Module. The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automa
Arduino The DS1307 is a real-time clock chip which can count seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year compensation. It's a great clock that can always keep track of time regardless of whether the microcontroller it connects to is powe...

When powered on, the client can connect to the server through a WebSocket connection and get data in real-time from the server. ESP32 Websocket Client Arduino Code The complete code used to configure the esp32 as aWebSocket clientcan be found at the bottom of this page. After adding ...
The two push buttons in the circuit are used to set time and date of the real time clock, button 1 (B1) is connected to RX pin (GPIO3) and button 2 (B2) is connected to TX pin (GPIO1) of the ESP-01 module. The Code:
The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock. Displaying the time is done via the use of two analog meters, each fitted with a ...
