What is Arduino?
Arduino is a free hardware and software platform based on microcontrollers (such as the ATmega328P). It is modular, inexpensive, and easy to program, designed for creating electronics, automation, and DIY prototyping projects.

What is it for?
Rapid prototyping: Create custom electronic devices (sensors, robots, IoT systems).
Automation: Control lights, motors, or internet-connected devices.
Education: Teach programming and electronics to beginners.

How can it be useful for Bitcoin?
DIY Hardware Wallets:
Build custom cold wallets to securely store private keys.
Example: Program an Arduino to generate and store BIP39 seeds.

Mining Monitoring:
Create sensors that measure temperature, humidity, or power consumption of mining rigs.
Real-time alerts (e.g., LEDs that warn if a miner is overheating).

Security Devices:
Physical authentication systems (2FA) to access exchanges or wallets.
Example: Use an Arduino + card reader to activate transactions.

Blockchain Education:
Simulate basic Bitcoin nodes or visualize transactions with LEDs.
Educational projects to understand how the network works.

Trading Tools:
LED displays that show BTC prices in real time (using APIs like CoinGecko).
Physical buttons to execute buy/sell orders (connected to exchange APIs).
Key Advantages for Bitcoin:
Low cost: Ideal for experimenting without investing in expensive equipment.
Customization: Adapt devices to specific needs (e.g., physical multisig).
Open-Source: Compatible with crypto libraries (BitcoinLib, Cryptolib).

Practical Example:
An Arduino + LCD display can be converted into a "Bitcoin Ticker" that displays the BTC price and alerts when it rises/falls by a defined percentage.
