Arduino UNO Curve Tracer Shield

The Semiconductor Curve Tracer Shield for Arduino can be used to plot I-V characteristics curves of resistors, diodes, LEDs, NPN and N-MOS transistors on an oscilloscope, a PC, or a smartphone over Bluetooth. 

The relationship between the voltage applied across an electrical device and the current flowing through it is represented graphically by an I-V curve (short for ‘current-voltage characteristic curve’). It’s one of the most common ways to figure out how an electrical component in a circuit works. The shape and features of the curve can also be used to extract key properties of electronic devices, giving you a better understanding of how they work.

The components’ I-V curves can help you understand their limitations and nonlinear operation. These curves can also be used to create circuit models and determine bias points, load lines, and device boundaries. 

Curve tracing, however, appears to be a lost art, and many engineers rely solely on the device manufacturer’s curves. Unfortunately, the manufacturer’s I-V curves aren’t always readily available, and some devices aren’t documented at all. Commercial curve tracers are available in some fortunate labs, but they are out of reach for many low-budget labs and experimenters.

you will be able to accurately plot, save and compare the I-V characteristics of a variety of devices, including diodes, Zeners, LEDs, NPN, N-MOS  transistors, voltage regulators and more. It will also enable you to test some types of integrated circuits.
