Build your own Arduino-based Laser Clock

Building different types of clocks is always an interesting task for Arduino enthusiasts, and this one certainly is a combination of imagination and Arduino – the laser clock. It used two servos – each with a laser pointer, controlled by an Arduino with a real-time clock to display the hours and minutes with laser beams on a wall:

Although the clock is quite imaginative, recreating it is very simple. The author hasn’t documented the Arduino sketch, however the same type of project is explained at the end of this tutorial. To get started with your own, using one of our Freetronics Eleven boards:

… in conjunction with our real-time clock module:

… will give you the base for a very accurate clock mechanism. For more information and design instructions, visit here. (Opens via Google Translate)
