Antivirus False Positive Notice

Some antivirus software may flag the Arduino IDE installer as a potential threat. This is a known false positive. Arduino IDE is completely safe and digitally signed. The software interacts with USB drivers and hardware ports, which can trigger heuristic scans. We recommend adding an exception or verifying the SHA-256 checksum below.

Transparency

Source
Transparency

Arduino IDE is fully open source. The complete source code is available for anyone to audit, build, and modify. We believe transparency is the foundation of trust. Every release is built from publicly accessible source repositories using reproducible build processes.

You are never required to download precompiled binaries. Advanced users can compile the IDE from source on any supported platform. Build instructions are included in the repository documentation.
