… and what's your next hack?
Introduction In a previous article we dealt with the problem of interfacing a 5V output signal to a 3.3V system. In this article we cover the opposite problem: we have a 3.3V output and we need to drive a 5V… (READ MORE)
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)
