Arduino Nano (ATmega328P) packs classic Arduino power into a breadboard-friendly form factor. Running at 16 MHz with 14 digital I/O (6 PWM) and 8 analog inputs (A0–A7), the Nano is ideal for compact wearables, robots, sensor nodes, and classroom builds in the Philippines. It keeps 5 V logic and the full Arduino library ecosystem, so it works with most sensors, displays, and shields via adapters.

Why choose the Nano

Tiny & tidy: Drops straight into a breadboard; perfect for handheld and embedded projects.
Beginner-friendly: Works out of the box with the Arduino IDE and community libraries.
Flexible power: USB programming plus VIN/DC input for stand-alone installs.
Stable 5 V logic: Plays nicely with common modules, relays, and many displays.

What you can build

Wearables & handhelds: small UI with 0.96″ OLED + buttons/encoder
Robotics: micro robot with L9110/TB6612 driver, line sensors, and IMU
IoT sensors: environment node (DHT22/BME280), distance (HC-SR04/ToF), LED indicators
Data loggers: microSD + RTC in a compact project box

Starter bundles (quick picks)

Nano Learning Kit: Nano + USB Mini-B cable + breadboard & jumpers + basic sensors

Pinout & power tips

A6/A7: analog-only on the Nano (no digital I/O on these two pins).
SPI: use the 6-pin ICSP header for reliable SPI across shields/boards.
3.3 V modules: add a logic level converter if a module is 3.3 V-only.
Drivers: If your PC can’t detect the board, install the correct USB driver for the onboard FT232/CH340/CP2102.

Learning path (Nano-focused)

Blink & inputs: LED blink, button debounce, tone
Sensing: DHT22/BME280, HC-SR04, light/LDR
Outputs: relays, servos, I2C OLED
Compact logger: microSD module + RTC

Compatibility & notes

Voltage: 5 V logic; some special Nano variants run 3.3 V/8 MHz—check your board label.
Cables: Classic Nano uses Mini-USB; some batches use Micro-USB—choose accordingly.
UNO vs Nano: same MCU and I/O count as UNO in a smaller footprint; perfect when space matters.
