It’d probably be unrealistic to expect a handheld computer powered by an Arduino Nano to do much more than that. It’s a tiny board with a 16 MHz ATmega328 microcontroller 32KB of flash memory ...

The Nano, on the other hand, comes in the smallest form factor Arduino offers, with the same 18 mm width but a shorter length at 45 mm and lighter weight at 7 g.

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

All it takes is an Arduino Nano R3 or comparable microcontroller, an RGB LED ring with 12 LEDs, a 16×2 LCD, a buzzer, and a momentary push button switch.

This is the SB116, an 8-bit programmer’s calculator powered by an Arduino Nano. It features a 128 x 64 pixel monochrome OLED display and can be powered by either a USB port or three AAA batteries.

Over on the Instructables website an awesome pair of smart glasses that are Arduino-based have been featured, that have been developed by Jordan Fung a 13-year-old developer and maker.

The Arduino Nano 33 BLE Rev2 is a significant leap forward in the world of microcontroller boards, designed to empower a diverse array of projects with its advanced capabilities.

The power of Espressif’s ESP32-S3 meets Arduino’s unmatched customer experience, documentation and community — all in the compact form factor of the Nano. Provides support for both ...

Arduino boards are very cool little system boards that let you do all sorts of cool electronics tricks by adding a few sensors and writing some code on your PC or Mac. Now theere is the Adruino ...

The total cost is cheap too, coming it at around $25 (assuming you have an old iPod). It's a bit of work to get everything in order, but it'll certainly bring a little use to that old iPod.
