In case you are looking forward to add something retro to your working table or bookshelf, then no other option is better than an Arduino controlled analog meter clock. Details about this project were recently shared by a tech geek who likes to call himself as”inventgeek”. An owner of multiple businesses, he loves to create new things that can make a difference to others lives. The analog meter clock created by him can be powered with the help of any USB cable. It is encased in a .118 Acrylic which also acts as a very good base for lighting up any place.
Anyone who wishes to take up this project will need a current Arduino. Though any Arduino will work in this case, but if you need your machine to be an efficient one it needs to be an Arduino. Apart from this, you will need a realtime clock module. These are highly useful little things that just need to be set with correct time once. Once you have set everything, they will keep going with their onboard battery. Another specific thing that will need you attention are the meters. For this purpose, you will need any 5V panel meter and if you wish to get any other model you can always try your hands on Ebay.
Finally, he mentions, you will have to find the right buttons as per the kind of look you want to give your clock. These will mainly help in manually changing the display time as and when needed. It is an optional part as the real time check module will need setting only once, rest it will sync with the timings on its own. But if you plan to add RGB LEDs to it, you will definitely need a button to change the colors. While building, the first thing that you need to ensure is that you have a good understanding of meters. Meters are usually polarity sensitive, in this project the positive lead will be attached with Arduino Analog pin. The negative lead, on the other hand, will be connected with radio’s Ground Pin.
