The theory, design, and implementation of a programmable Internet of Things digital inductor circuit is presented. Since the inductor is implemented in digital signal processing, the values for the inductance are easily modifiable through an Internet of Things interface, enabling remote access to the physical hardware. The system was implemented on a commercially-available microcontroller board using a client-server scheme over ethernet connection. A control interface running on a laptop was then used to change the inductance remotely. Simulation and implementation of the design are presented and are shown to match at a sample rate of 100 kilosamples per second. Since the design method constitutes a digital approach, performance is expected to scale with higher-speed hardware.
