I have a project to control a linear actuator with a StickC and a SEEED 2 relay board. I want to add a set of reed switches to provide feedback to my code when the window the actuator is controlling is fully open or closed. Can I wire the reed switches directly to the StickC or do I need resistors/voltage dividers?
Additionally I would like to power the StickC from the 12VDC power supply. I have some BEC circuits but they only lower the voltage to 5vdc. Can these be used with the StickC? Do I connect to the BATT, 5VDC or 3.3?
