It takes a handful of LED arrays with an integrated driver, an Arduino Nano ... microcontroller projects. If you want really minimal, you could go with a 4 LED clock (but you better know the ...
This replica uses LEDs driven by an Arduino Nano and a real-time clock. Since the RTC gives hours from 0-23 and minutes and seconds from 0-59, a couple of shift registers and some modulo ...
Some beginner-friendly Arduino Uno projects ... the same clock speed of 16MHz, SRAM of 2kB, EEPROM of 1kB, and flash memory of 32kB. However, one notable difference between the Nano and Uno ...
