A simple setup using an Arduino Nano and an LCD Keypad Shield to set the date, time and alarms for a DS3231 Real Time Clock (RTC).

UNO Multiple time zone clock using the DS3231 and LCD Keypad This clock shows 3 time zones as well as the date. It utilizes a DS3231 RTC (Real Time Clock) and a LCD Keypad Shield.

This is the complete circuit diagram explaining how a 16×2 LCD and RTC DS3231 module is connected with the Arduino. This schematic is designed in Cadsoft eagle 9.1.0 version. If you want to learn how to make a schematic and PCB, then watch the tutorial.

It's basically a clock with two buttons for setting the time and date. It doesn't look that great on the breadboard with all those wires but it does the job and it can be simplified by using a I2C display, but I'll cover that subject in a future instructable.

In this project, the DS3231 (real time clock) module has been used to get the current time, date and temperature. They are al displayed on the 20x4 LCD screen. To keep track of time even if the main power source is removed, the DS3231 has a backup battery mounted at the back of …

May 5, 2018 · In this article, I will guide you how to set up your own DIY real-time clock, and then you can use your own project to integrate this project, but I found it very difficult to use the RT323 chip DS3231 when using the Arduino. Just set the time is …

Interface the DS3231 Real Time Clock module with the Arduino board. The DS3231 RTC does accurate timekeeping, set alarms, output square waves and get temperature readings. ... Arduino Membrane Keypad. Arduino PIR. Arduino DC Motor. Arduino RTC. Arduino Sensors. Arduino DHT11/DHT22. Arduino BME280. ... Arduino LCD. Arduino 8×8 Dot Matrix ...

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.

Set up your breadboard circuit with this circuit diagram containing the DS3231 module, I2C LCD and four push-button switches with 10 kilo-ohms pull-down resistors, all connected to the Arduino Nano. The Arduino Nano uses pin A4 for SDA and pin A5 for SCL I2C communication.

The module also comes with a quite accurate temperature sensor which we will be using to get temperature readings. The collected temperature and clock data is then displayed on the 16×2 LCD via the Arduino. LCD Keypad Shield Required Components. The following components will be needed for this tutorial. They can be purchased via the links ...
