In this project, we made a coffee alarm using DS1302 RTC Module and HM-10 Bluetooth Module. This DIY Coffee Alarm will remind you when you should drink coffee.

This is basically the arduino.cc sample turned into a library for easier reusability. It's not perfect but it does the job. void clockWrite(byte year, byte month, byte day, byte wday, byte hours, byte ...

The DS1302 is supported by a few Arduino libraries and only requires three pins on the microcontroller to operate. With the current design you can upgrade for example the 3 displays alarm-clock to ...

He’s using an Arduino Uno and an Ethernet breakout board to hook it up to the network. This allows him to send text messages to himself when the alarm system is armed, disarmed, or triggered.

DS1302 high-precision RTC [180620] A small, DS1302-based Real-time Clock (RTC) module with on-board, 20-ppm oscillator. This is a small DS1302 PCB with on-board oscillator. This means that if you need ...

Put aside all of the projects that use an Arduino to blink a few LEDs or drive one servo motor. [IngGaro]’s latest project uses the full range of features available in this versatile microcon… ...

Welcome to the Arduino Fish Feeder project! This project allows you to automate the feeding of your aquatic pets using an Arduino board, a DS1302 real-time clock module, and a servo motor. With ...
