LCD, and maybe the buzzer. Power the arduino through an adapter. The reason is because the time resets if it is disconnected from power. That is why batteries are not good for this. You can try using an RTC like DS1307 that keeps time even if the arduino is off. I did it without ...

I don't want to use ethernet shields, but I want to access Arduino devices from local networks or the Internet. Is that possible to do with Arduino Control Center? I am clicking on the DIGITAL OUTPUT component in a desktop application, the led diode is connected on this pin, but nothing...

Arduino Powered Sunrise Alarm Clock With Neopixels: I'm not a fan of getting up. I'm also often very tired in the mornings (and usually grumpy. But I digress.) I was doing some reading about how to get better sleep when I came across a guy who did some s
Once we connect the module we need to program the Arduino Board to work with the Real Time Clock. However, when it comes to programing a communication between Arduino and an I2C module the code isn’t that small and easy. Luckily, there are already several libraries for the DS3231 RTC wh...
RTC clock with manual adjust & alarm, thermometer & higrometer using Arduino I use led display named LFD080AAG-103-01 (4-digit 7-segment common cathode) For RTC clock I use DS1307 homemade module, but works without changes with DS3231 module. For thermometer and higrometer it use DHT11...
or a single use. The alarm state can be checked using library functions or can pull down the the MFP (multi-function pin) for a hardware interrupt or other action. The MCP7940 allows for software trimming and the library has functions which support fine-tuning the RTC to increase accuracy....
