![]() It can be customised by adding words or modifying to another language and has options to reduce the brightness or add LEDs for the single minutes. The word clock has an Arduino controller and real-time clock and lights up words telling the time. It’s a fun, useful project, guaranteed to be a talking point and I undertook to build one. ![]() This word clock is available as a kitset from his website. It was developed by Doug Jackson as a more affordable QLOCK 2 which he says he saw on a hobbyist’s website where he was struck by the clock’s beauty and its high price. or p.m.Ī word clock is ideal for numerically challenged modern youth who can’t tell the time or for those of a literary persuasion. One modification I’ve already planned is to change the colour of the “IT IS” based on a.m. This adaptable project can also automatically dim the display at night between 7.00pm and 6.59 am. Because the software (sketch) in the processor has a few added extras, it could illuminate extra words or a single LED for the minutes 1-4. On the hour and up to four minutes past is just O’CLOCK. At 17 minutes to the hour, TWENTY MINUTES TO will still be lit up. For example, the code for “ten past” is an instruction for when the time is “greater than 9 minutes AND less than 15 minutes.” The result: real-time 13 minutes past will still have TEN MINUTES PAST lit up. Our display lights up each five-minute period in the hour the processor checks to see which of the words the minutes are on or between and illuminates that LED output.Īnything up to four minutes past a number is rounded back to that number. ![]() The processor establishes if the minute hand is PAST or TO the hour from the RTC information between 0 and 59. The RTC provides hour information as 1-24 and the processor decides what hour to display, based on the minutes and the hour information. It outputs the time in a string of numbers the processor can read and manipulate. An optional battery backup keeps the RTC running during power outages.Įvery 60 seconds, the processor polls the real-time clock chip (DS1302) which accurately keeps time. The PCB contains a power supply, pre-programmed processor chip, a real-time clock (RTC) and output drivers to illuminate the LEDs. It is based on an Atmel 168 processor chip as used in Arduino, is programmed using Arduino and fitted into a custom-made printed circuit board (PCB). Word Clock is a project created by Doug Jackson using Open Source (and has been evolving into the product you see here.
