In this article, we will clarify how to build a bidirectional 2-bit mux circuit that can be used with I 2 C lines. The circuit also has the extra functionality of operating as a level shifter, if ...

There are different methods to measure current. One method is to use a resistor across a current output and measure the voltage. The voltage across the resistor is measured using ohm's law: where I is ...

If you ever find yourself swapping between a mix of audio inputs and outputs and get tired of plugging cables all the time, check out [winslomb]’s audio multiplexer with integrated amplifier. The ...
