Tiny85FanControl

A temperature-controlled fan system powered by an ATtiny85 and a DS18B20 temperature sensor.

⚠️ This project is a work in progress and may not yet be suitable for all use cases.

Hardware Requirements

You'll need the following components:

• ATtiny85 microcontroller
• USBtinyISP (or compatible ISP programmer)
• DS18B20 1-Wire temperature sensor
• Passive components (resistors, capacitors, etc.)

Refer to the Bill of Materials (BOM) for part numbers and quantities.
