Sigh. This Arduino stuff is a convoluted mess.
One question: C.
A. "Adafruit Assembled Data Logging shield for Arduino" - (
https://www.adafruit.com/product/1141)
B. Metro 328 BUT, there are two options. What is the difference? Reading the descriptions did not help. I plan to use with the 1141 shield listed above.
https://www.adafruit.com/product/2488??C. Instead of DHT22 temperature sensor, you suggested an I2C sensor on a breakout board
https://www.adafruit.com/category/56As I understand, the Metro 328 (/2488) is on the bottom, with headers? that connect the logging shield (/1141), and then ???? another set of headers? to connect the temperature sensor breakout board? There would be a stack, Metro on bottom, then logging shield, then sensor breakout board? The temperature sensor (/56) uses Arduino language, which I guess is a C/C++ variation? The Metro 328 (/2488) and logging shield are a compact unit. Using a breakout board and breadboard, makes it all cumbersome. No interest in Feather - too small, not C/C++.
