Arduino Pocket Computer featuring calculator, stopwatch, calendar, game and phone book

Plan was to test Arduino Nano board, i had idea to make Pocket Computer using OLED display and few input/output components. Plan was to include calculator, games, stopwatch, calendar, phone book. Will arduino nano handle thease kind of task. Arduino is fast enougth when using OLED display but memory is not that great. Oled library alone will need lots of memory. For this project i designe custom PCB, PCB is produced by PCBWay https://www.pcbway.com/ Pcbs ariverd very fast and i also got free stikers and pen. Quality is great like always. I recomend pcbway. If you want to order this PCB (version 1 for oled with (GND,VCC,SCL,SDA) configuration) you can order it here: https://www.pcbway.com/project/shareproject/ArduinoPocketPc_78571953.html and here is version 2 for OLED with VCC,GND,SCL,SDA pin configuration. https://www.pcbway.com/project/shareproject/Arduino_PocketPC_Version2_ef5fac7c.html Here is my code: https://github.com/VolosR/OledPc Here are libraries I used, just extract them in "Arduino-libraries" folder: https://drive.google.com/open?id=1Mni5eaIdQk2R2KEkVJJafdj1oic1KtmU You can also buy me a coffe at: https://ko-fi.com/volosprojects
