Project Description

In 2018, as part of the Computer Science Club activities at a high school in Eisenach (Martin-Luther-Gymnasium), the pupils had the idea of building a binary clock for the school building. This project was successfully implemented in 2019.

The project enabled the pupils to put the knowledge they had previously gained about microcontrollers, single-board computers as well as the control of LEDs via input/output pins to practical use.

The clock has an economic design and shows the current time in the binary system. The hours, minutes and seconds are each represented by two columns with up to four rows. One column stands for the 10's place and the other stands for the 1's place. In each row, starting from the bottom, the LEDs correspond to the numbers 20, 21, 22 or 23. If, for example, the bottommost and topmost LED are illuminated in the 1's place of the seconds column, this corresponds to 20+23 = 1+8=9. The time hh:mm:ss is calculated from left to right digit by digit.

The simple and natural wood look adds to the minimalist design. The LEDs illuminate the diffusing plexiglass on the front side. For design reasons, no markings or explanations have been used. An understanding of the binary clock is obtained through observation. Of course, everyone is also welcome to ask for an explanation.

Fun fact: The clock is deactivated by control software when the school is closed in order to prevent the alarm system being triggered by shadows.
