Boost converters, like other switchers, have traditionally received their control signals from a dedicated circuit. However, a recent trend is to integrate simple switching-power-supply building blocks into generic devices, such as ...

Here are some simple tips for servo systems that may improve productivity and prevent costly downtime. To help engineers and design teams get all the performance possible from servo systems, here are some of the more troublesome servo predicaments ...

Despite the increasing availability and declining cost of on-chip analog peripherals, the humble PWM DAC retains its appeal as a “free” DAC [ 1 ] that can repurpose an uncommitted DIO pin and counter/timer module, add a simple low pass ...

Many applications, such as medical therapies, magnetic stirrers, and induction heating, call for a rotating magnetic field, which you can generate by attaching multiple permanent magnets to a dc motor. This technique involves problems, including ...

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 ...
