Hello all! I wanted to share my first ever embedded project. Though it really only scratched the surface it opened my eyes to the vastness of the world of embedded engineering. I wanted to hear some critiques as well as what direction I could take it the project in order to learn more about the low level stuff. This project really ignited a strong interest in the subject and I would like to hear from you guys what you think the best direction to continue on is. The project is a wearable wristband that reports HR through LEDs and to an app via BLE. The mcu is an esp32c3 and a MAX30102 as the sensor, everything I used was pretty high level I want to know what resources youd recommend I use to start getting into the lower level programming. submitted by /u/slapbac2 [link] [comments]
