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, ...

With just a few components, you can provide a translated signal from industrial and PLD sensors that connects safely to a microcontroller, with the added bonus of supplying 7.5 mA of regulated power.

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 ...

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, ...

[manuka], aka [Stan Swan] is a teacher in New Zealand who enjoys enlightening his students on the wonders of electrical circuits. He primarily uses “snap connector” circuit kits, sold under the ...

Voltage-to-current converters that feed grounded loads are common in industrial measurement and control applications. The conventional "textbook" circuit uses both positive and negative supply rails.

The first program anyone writes for a microcontroller is the blinking LED which involves toggling a general-purpose input/output (GPIO) on and off. Consequently, the same GPIO can be used to read ...

A microprocessor is an integrated circuit that contains no memory. A microcontroller has the ability to store information. The size of a circuit can be significantly reduced. This is because ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...
