Summary

Convert a 12v signal to 3.3v TTL level output compatible with Arduino or other microcontrollers


Description

This circuit lets you convert an externally powered input switch to 3.3v level TTL. The separate 3.3v power supply can be substituted with a 5v if thats what you need. Both PS can share a common ground, which is precisely what this was designed for.
