This paper describes a memristor emulator made up of an arduino-controlled digital potentiometer (DigPot) implementing the mathematical equations governing the HP memristor model. The emulator composed of off-the-shelf electronic components come in handy at a time where reliable physical devices are yet to be available. The arduino samples the voltage difference between the two terminals of the DigPot's resistance network, calculates the resistance and then updates the DigPot through the SPI interface. Data is collected through the serial port and plotted in real time. This hobbyist-style do-it-yourself approach can be used to initiate students into the basic theory of memristors.

Abstract
This paper describes a memristor emulator made up of an arduino-controlled digital potentiometer (DigPot) implementing the mathematical equations governing the HP memristor model. The emulator composed of off-the-shelf electronic components come in handy at a time where reliable physical devices are yet to be available. The arduino samples the voltage difference between the two terminals of the DigPot's resistance network, calculates the resistance and then updates the DigPot through the SPI interface. Data is collected through the serial port and plotted in real time. This hobbyist-style do-it-yourself approach can be used to initiate students into the basic theory of memristors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
