The artificial candle is controlled with an infrared remote control, and all of the code for the project is available on the project site if you want to build your own.

The code is for directly controlling the LED matrix (I had made a 10X8 matrix) through Arduino Uno. Here, I have used multiplexing which makes the task a bit difficult to understand at first.

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...
