BIVBlog #50: Floating Microcontroller Inputs, Single Throw Switches and Pull-Up/Pull-Down Resistors

Feeding analog voltages to digital microcontroller inputs already got us some interesting effects, but what about leaving an input pin entirely disconnected? All of a sudden microcontrollers become sensitive to the weather outside, and the clothes we wear—or any other source of electrostatic. The easy way to deal with this is to always ensure that […]
