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.
Integrating processors, sensors, and data exchange functionality into everyday objects, the Internet of Things (IoT) pushes computing capabilities far beyond desktops and servers, weaving computation ...
This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...
When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...
One reason of Electromagnetic compatibility (EMC) problems with microcontrollers is poor power supply decoupling. A correct and sufficient way of decoupling power supply lines is necessary in order ...

I only have 5V but I need 3.3V — A voltage divider circuit that creates voltage with two resistors
I only have 5V but I need 3.3V. The battery voltage is too high to connect directly to a microcontroller. That is when a ...
Starting on Monday, July 25 and running through July 29, Design News will present the free course, How to Select the Right Microcontroller for an Application. Each class runs an hour, beginning at ...
