5V to 3.3V logic level translation/conversion/shifting: how to interface a 5V output to a 3.3V input.
Many times we must interface 5V to 3.3V devices. This occurs very frequently on Arduino, but also other applications may need 5V to 3.3V ICs or systems to communicate. In many cases, some sort of logic level shifter/translation/conversion circuitry might… (READ MORE)
