When you are working with battery depending low power-consuming circuits, then you may need this innovative power switch. The concept is to save energy while the device is not operating but the battery is connected. Why we need to save energy We ...

The most common method for interfacing multiple switches multiplexing allows for the connection of (N/2) 2 switches with N microcontroller I/O lines. The method described below, which has its roots in an LED interface technique commonly known as ...

Using a PN-junction diode for temperature measurement usually depends on its 2 mV/K temperature coefficient. Conventionally, you must amplify and digitize this voltage with an ADC before you can use the value in a microcontroller. Less well-known ...

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 ...

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 asked to design ...

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 economize on ...

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 ...
