Atmega328p Nano

Q: What is a Claude Code skill and how does the Atmega328p Nano skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Atmega328p Nano is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

Firmware development for the Arduino Nano (A000005, ATmega328P @ 16 MHz, 5 V) — its 30 KB usable flash, 2 KB SRAM, 1 KB EEPROM, 8-channel 10-bit ADC, six 8-bit PWM pins across three timers, UART shared with the USB-serial chip, I2C on A4/A5, SPI on D10–D13, sleep modes, and the Arduino AVR core + PlatformIO setup around them. Use when working on this board or any ATmega328P Nano clone (FTDI or CH340 USB): project setup, platformio.ini, old-vs-new bootloader uploads, pin mapping, A6/A7 restrictions, timer/Servo/tone conflicts, the 2 KB SRAM budget, analog references, powering from VIN, ICSP recovery, or debugging why something on the board does not work.

From the source SKILL.md

Board-specific firmware knowledge. The Nano is simple enough that every failure mode is silent — the sketch compiles, uploads, runs, and does something subtly wrong — so read the reference file rather than guessing.

What this skill does

Atmega328p Nano is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/atmega328p-nano/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when working on this board or any ATmega328P Nano clone (FTDI or CH340 USB): project setup, platformio.ini, old-vs-new bootloader uploads, pin mapping, A6/A7 restrictions, timer/Servo/tone conflicts, the 2 KB SRAM budget, analog references, powering from VIN, ICSP recovery, or debugging why something on the board does not work.

Who uses this skill

The Atmega328p Nano Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 211,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
