About 12 mA: bright and safe.
Your first output: D13 switches the yellow L LED on the board and an LED on the breadboard on and off, with a pause after each change.
| Pin | Connects to | What it does |
|---|---|---|
D13 | Resistor → LED anode (+) | The sketch switches it HIGH and LOW; L follows it on the board. |
GND | LED cathode (−) | The current returns here. |
