Your first Uno uploadOpen in English ↗

Step 5 — Try it and troubleshoot

The small L LED on the Uno blinks twice per second. Change both delays to 1000 and upload again.

If it does not work

Choose Arduino Uno and the correct USB port. Use a data-capable USB cable. Disconnect external wiring before diagnosing an upload failure.
