Ep. 02: From Blinky to BME280 - Learning STM32 the Maker Way

Welcome back to Build, Create & Learn — A Maker’s Journey! In this episode, I’m taking you along on my early adventures with embedded programming using the STM32 microcontroller.

From that first blinking LED to the moment I finally got sensor data from the BME280, it’s been a ride full of bugs, head-scratching errors, and small wins that felt huge.

I’ll walk you through:

• How I got started with STM32 and why I chose it
• The common mistakes that slowed me down
• Wiring up and reading from the BME280 sensor
• What I’ve learned (and what I still don’t understand)

If you’re curious about embedded development or just enjoy the learning journey behind the scenes, this one’s for you. Whether you’re a beginner or someone looking back at their first “blinky” project, I hope you find something relatable in the process.
