The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

There are only four components: an Arduino Nano, a DS3231 RTC module, a SSD1306 128×64 OLED module, and a momentary pushbutton.

GitHub - dev65808/WiFi-Digital-Clock: This project uses an ESP32 and an Arduino Nano to create a real-time environmental monitoring display. It collects temperature, humidity, CO level, and time, and ...

LED Propellor Clock Fan Led Propellor Clock Fan is a clock with both digital display as well as analog display. It is made up on a PCB with the help of Arduino as a microcontroller to receive and send ...

The Nano Every is a pin-equivalent substitute, so previous code and wiring will still work. Arduino has also swapped out the Nano's mini-USB connector in favor of micro-USB.

It has almost similar specifications as the Nano's microcontroller, which features 16 MHz clock speed, 32 KB flash memory, and 1 KB EEPROM. However, it comes with a slightly larger SRAM of 2.5 KB.

512KB SRAM and 16KB of RTC SRAM Dual-core CPU at 240 MHz clock speed USB-C programming port The Arduino Nano ESP32 is available to order today in the Arduino Store, starting at $18.
