LED Circuit Driver (60¢): Circuit drivers are used in place of complicated electronics code.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

The rig is based on an Arduino Uno and has a few circuit components that can be used as references and generates data on the behavior of the memristors under various situations.

Students will get an introduction to Arduino microcontrollers, learn how to design a circuit and make a PCB, and get familiar with all the tools they’ll need in order to do the job.
