[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ...

An HX711 readout chip measures the resulting voltage and converts it to a digital code that is sent to a microcontroller, in this case an Arduino ... As with any analog sensor, calibration and ...

Inputs are components that send data to the Arduino. They're either digital (only sends HIGH or LOW signals) — think pushbuttons and PIR motion sensors — or analog (sends a range of data ...
