There is no better way to learn electronics and coding than programming Arduino or Raspberry Pi units. The good news is there are already plenty of fun Arduino projects for you to try. This Glow-in-the-dark Laser Clock is worth a look. It draws the time using an Arduino Uno.
The clock uses a RTC unit to keep accurate time. You will need 3 servos, TinyRTC, glow in the dark sticker sheets, and a few other simple components to get started.
