Interfacing LM393 Voltage Comparator Module with Arduino
A comparator module based on an LM393. By means of the adjustable resistor you control at which voltage the digital signal goes from 0 to 1 (an LED will also light up on the board).
With 2 pins for the input voltage and 4 pins for VCC, GND, AO (analog off), DO (digital off (on/off).
Operating voltage: 3.3 V to 5 V
In the form of the output: analog output
digital output, the output threshold
