Microcontroller power source considerations for Arduino

November 17, 2020 By Scott Thornton 3 Comments

Arduino power source

Powering an Arduino has a little magic to it. It wasn’t obvious to me when I first started working with them, but Arduinos have on-board regulation. Taking advantage of this allows for longer power supply wiring runs by using a higher voltage power supply than the nominal 5V or 3.3V needed by the microcontroller (MCU) […]

8-bits and counting: 8-bit MCUs are still going strong

November 6, 2020 By Scott Thornton Leave a Comment

Aeneas nanosatellite

Microcontroller units (MCUs) never stop evolving; a more functional, featured MCU follows every model. Embedded systems have grown with continually growing MCU technology, yet there are many traditional MCUs that are still selling in high volumes. Atmel 8051 is one of those legendary MCUs which have developed a considerable demand in the market. The Atmel […]

What is the HART protocol?

November 3, 2020 By Nikhil Agnihotri Leave a Comment

Data communication over analog signals is a common process. In automation, the data is communicated to and from controllers with several different process instruments. Quality is important as the controllers and smart instruments must communicate over long distances.  Additionally, the data communication between a device and a controller must be dictated by a protocol (i.e. […]
