How I Connected
In this video, I connect an STM32 microcontroller to an Arduino using serial communication (UART). I programmed the STM32 to send status messages about the LEDs, and the Arduino receives them using the SoftwareSerial library. #stm32 via #arduino #stepbystep

You'll see:
How the STM32 reports which LEDs are ON
How the Arduino reads the data in real time
What happens when invalid inputs are sent
Troubleshooting connection issues
I also tried using an STM32 from the zero series... and well, that part didn’t go as planned 😅
Stay tuned — I’ll keep testing and post updates soon!
