We meet once per month and each time we have presentations - always on different and fascinating subjects, from the Beaglebone Black to GBD to creating libraries in C. Each presentation is given by an expert in the subject, most of whom work for engineering firms such as USSI and Logikos, so they are quite knowledgeable about the products and the fields.
We also have demonstrations of our most recent projects, provide advice or assistance to each other, and discuss the latest technology. I have been able to demonstrate my projects to the group, like the thermostat I designed that activates a fan when a specified temperature is reached.
I am so glad I found the Arduino/Microcontrollers Users Group! I have yet to meet a more helpful or knowledgeable group of engineers!
