I have earlier published a Digital Clock project, and that was my first project on Arduino. That project has only limited features ( even without a facility for time setting ) due to constraints in getting sufficient no of pins on Arduino Nano to write the code. Here by adding an InfraRed remote, it give me flexibility of incorporating all the features that requires ( may be more if required), with out the need of extra pins and also avoiding slide and push switches. Also IR remote make the clock very compact and convenient to set and use.

Also avoiding bread board, jumpers etc, I used a home made PCB to make the project clean, compact and an usable for normal home use.

I am publishing this project as a new one, since the previous project’s sketch was extensively changed to incorporate IR remote and adding additional features, and also it is a finished project.

EXPANDED TECHNICAL DETAILS

Remote Temporal Navigation

This project builds a full-featured digital desk clock that can be configured entirely or remotely from across the room.

  • IR Protocol Decoding: Uses a TSOP38238 IR receiver. The Arduino (Nano R3) decodes the NEC or Sony protocol signals from a standard TV remote, allowing the user to set the Hour, Minute, and Alarm time without physical buttons.
  • 7-Segment Display Hub: Manages a 4-digit display using the TM1637 or MAX7219 driver, which reduces the required pins from 12 to just 2 (I2C or SPI).

Precision

  • DS3231 RTC Sync: Relies on a high-precision Real-Time Clock to maintain time even when the main Arduino is powered down.
