The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

"Hydraulic Schematics and Basic Circuit Design" provides an overview of basic hydraulic circuit configurations and the standard fluid symbols in fluid schematic diagrams. A hydraulic schematic diagram ...

The properties of propagating surface plasmon polaritons (SPPs) along one-dimensional metal structures have been investigated for more than 10 years and are now well understood. Because of the high ...

Using eight digital inputs, this circuit simplifies decoding of the common membrane 4x4 keypad matrix and eliminates the traditional requirement of scanning rows or columns. Any X-Y switch matrix, ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

There are two groups of classic circuits: those which have served us well in the past, but have been superseded by better designs, and those which are still in use, perhaps with updated components. In ...

"Basic Pneumatic Schematics and Circuit Design" provides an overview of different common pneumatic schematic symbols, including air treatment symbols; pressure, flow, and direction valve symbols; and ...
