Connect the cathode of the LED to one terminal of the resistor.
Connect the other terminal of the resistor to ground (GND).
Instructions:
Ensure that the resistor is calculated correctly to prevent excess current through the LED, which might damage it.
The typical forward voltage of an LED is around 2V, and the current is around 20mA. You can calculate the resistor value using Ohm's Law: R=ILEDVsource−VLED
Assuming a 3.3V source from the STM32: R=20mA3.3V−2V≈65Ω
A 220Ω resistor is a safe standard value to use.

- 1 x LED
- 1 x Resistor (to limit current through the LED, typically around 220Ω to 1kΩ)
- 1 x STM32H723VET6 microcontroller
GPIO Pin Selection:- Connect PA5 to the anode of the LED.
- Connect the cathode of the LED to one terminal of the resistor.
- Connect the other terminal of the resistor to ground (GND).
