DIY Nokia 5110 Display Design Clock with Arduino Nano

thingiverse

This is a neat little clock using an 5110 display of an old Nokia cellphone. If you want, you can call it a smart clock, as many features can be programmed and loaded onto the Arduino microcontroller which drives the display module. I got inspired by the "Desktop Widget by smily77" (http://www.thingiverse.com/thing:857858) Materials Needed Material For this project, you'll need: an Arduino Nano board a DS3231 RTC module an 5110 display module two switches some wires some resistors a summer (optional: if you want an alarm) and a 3D printer - of course Instructions ** Casing ** The case consists of two parts: the first one is the body where the display module is snapped into place and / or glued in depending on the precision of your printer. The second part -the back panel - holds the Arduino Nano board in place and supports the other components. Due to the tight fit of the Arduino, you don't need to glue it in place even if you plug it in and out. ** Hardware ** I've drawn a diagram for the wiring which can be found on GitHub: https://github.com/meiniKi/Nokia_5110_Design_Clock/blob/master/wiring_diagram.png Please consider that the display is supplied by 3.3 volts! A 5-volt supply will blow up the display. ** Software ** The software is in progress and can be found on GitHub. Please pay attention to the frequent changes: https://github.com/meiniKi/Nokia_5110_Design_Clock/blob/master/Clock5110.ino ** Updates ** 11.03.2017: new software version available on GitHub I like sharing my projects so that everyone can rebuild and improve them. To present it in a way also not-so-experienced visitors can rebuild it is quite time-consuming. If you like the project, you can support me by leaving some tips, so I can buy new modules and electronic components for further projects.
