Input circuits

Arduino basic binary input

Three most basic digital input types detailed and discussed lightly.

Arduino basic analogue input

Analogue signal level measurement at its basic level. If it is on, how much is it on anyway? Basic level shifting and scaling with an opamp.

Arduino advanced binary input

Basic isolation techniques for digital input.

Arduino advanced analogue input

Small signals can be hard to measure if not preprocessed. Some standard methods for unbalanced and balanced voltage and current measurement and isolation techniques.
