John Bradnam hackster.io Use the latest ATtiny processors in the Arduino Environment. These have the memory capacity of ATmega chips in smaller and cheaper packages. Things used in this project Hardware components: Microchip ATTiny1614 , 14 Pin ...

By Ivan Serrano EEWeb For most embedded designers, light-emitting diodes (LEDs) are simple components that are used as visual indicators. They typically involve a minimal circuit, and controlling the LED is typically only a matter of toggling the ...

Vardan Antonyan EDN Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts. Fortunately, you can convert a ...

Christopher Dean, Texas Instruments Electronic Design By adding a digital potentiometer and ratiometric division to a voltage-reference IC's feedback loop, you can set the reference's output voltage using a digital code. Adjustable voltage ...

Aubrey Kagan Embedded After my previous review of more traditional ways of reducing the I/O lines needed to drive LEDs/displays and keyboards/switches, here I'm looking at the nominally new method of Charlieplexing. Back in about 1982, I was ...

Aubrey Kagan Embedded Webster’s Dictionary defines “multiplex” as “many” or “multiple”. Coincidentally, in an electronics context the word can have several meanings. Whilst they all share the intention to ...

The Ruggeduino is a ruggedized Arduino-compatible microcontroller board (Figure 1). Features include overcurrent and overvoltage protection on all I/O pins and 5 V/3.3 V outputs, ESD protection on all I/O pins and USB port, total microcontroller ...

Nancy Friedrich Microwaves RF As wireless-sensing components boost efficiency and other performance criteria, energy-harvesting solutions are moving beyond a niche and into everyday applications. Energy is all around us whether the sources are ...

John Donovan Digi-Key With more and more consumer, medical, and industrial devices communicating wirelessly, the so-called Internet of Things (IoT) is set to explode over the next several years. Many, if not most, of these devices will be ...

By Derrick Klotz, Freescale, Canada It's a great feeling when you get your first microcontroller (MCU) program running. It might just be the simple blinking of an LED, but you're learning something new and beginning to feel that you understand it. ...
