A version of thie article appeared in the February 2012 issue of Test & Measurement World. See the PDF. Many industrial systems use the 4–20-mA loop to transmit measurements from sensors to displays, ...

The MCP120 is a microcontroller voltage supervisory circuit with open drain output. This voltage supervisory device is designed to hold a microcontroller in reset until the supply voltage has reached ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

This file type includes high resolution graphics and schematics when applicable. Laboratory data often appears as Gaussian curves, and today's laboratory data-acquisition software is designed to ...

Drawing and analysing flowchart diagrams involves elements like count, compare, macro, do macro, end, increments, decrements, and expressions. Microcontrollers (PICs) are used in control systems, ...

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. The ...

There is one thing that unites almost every computer and logic circuit commonly used in the hardware hacking and experimentation arena. No matter what its age, speed, or internal configuration, ...

Lots of programs take data from a file and create an X-Y graph under Linux. Desktop applications like xplot, gnuplot or even PHPlot do a great job. But, what if you want to see how a physical process ...

Why feedback is important in system control? Systems approach: input (sensors like thermostats), process (microcontrollers), output (actuators like heaters). Feedback ensures accuracy and stability.

Slimmed-down version of Python, rebuilt from the ground up, is designed to run fast and lean on microcontroller hardware The Python programming language’s flexibility and ease-of-use have made it ...
