You can turn a single analog pin on a microcontroller to a 4-bit input with 1-bit output with only some resistors, push button switches, an LED and a single JFET… It has been done forever… ...

The circuit in this Design Idea provides a way to convey mixed analog and digital inputs into a microcontroller using one input pin. The output of the circuit connects to a micro-controller's ...

The OUTTREE= data set contains one observation for each observation in the input data set, plus one observation for each cluster of two or more observations (that is, one observation for each node of ...
