Arduino-Based Geiger Counter

An Arduino Uno-based Geiger counter project that counts pulses from a Geiger-Muller tube and displays radiation readings on an SH1106 128x64 OLED.

Safety: A Geiger-Muller tube requires a high-voltage supply. Use appropriate electrical-safety precautions when building or testing this project. This is an educational/experimental project, not a calibrated safety instrument.

Getting started

1. Verify the actual hardware connections before powering the circuit.
2. Install the required Arduino and Adafruit libraries.
3. Open Firmware.ino in an Arduino-compatible environment and compile for the intended board.
4. Validate and calibrate readings against an appropriate reference before relying on measurements.
