I am receiving my first core as a xmas present and got a sneak peak and I am absolutely surprised how small it is!
However I have a few questions mainly around the voltage logic, as I have programming skills but next to nothing in electronics except for some tinkering on an Arduino UNO.
Since the Spark runs on 3.3V does this mean I wont need resistors on
LEDs or is the .3V still too much?
If I have a sensor such as a RF Receiver or temp. monitor which runs
on 5V power, will the data line need to be reduced to 3.3V? I assume
in such scenario I can power the 5V through the VIN (using USB)
When I do flash my own code onto the Core how do I get the Tinker
Do I need to do any prep work before I use the Core, such as
upgrading the C3300 firmware?
Sorry for all the questions and I am sure there are more to come but I cant wait to be part of the community
