Microcontroller, code, and sensor related solutions
This site is dedicated to sharing what I have learned
with respect to programming microcontrollers, and the
use of electronic sensors and related components.
I only share what I have personally learned and tried so that
you get access to proven solutions.
Do you need help developing or customizing a IoT product for your needs?
