This frequency is measured by an Arduino that plots a graph of the received frequency on an OLED display. As the coil is passed near metal objects, the oscillator frequency changes, and this is ...

Serial Plotter is an amazing tool available in Arduino IDE (from v1.6.6) to visualize the “returned” data beyond just seeing numbers spit out onto the traditional serial monitor window. The Arduino ...

Celebrate 20 years of Arduino software and tools with a spotlight aimed at industrial automation, AI, rapid prototyping and more.

Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, … ...

The two graphs should appear, and the plot will change as data streams in. Scaling is automatic by default and will work for many situations (Figure 5). That's pretty much the rundown on plotting real ...
