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 ...

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...

Data security is very important in data transmission. There are many methods to make the data to be secure. One of the methods is by using cryptography algorithm to encrypt the data. Using the ...

In need of a simple microcontroller board for your project? Then, an Arduino board might be exactly what you're looking for. This open-source hardware platform comes in a multitude of versions, from ...

Electronic Design's own Lou Frenzel is updating one of his textbooks—and is soliciting advice from readers on microcontroller content to include. I am in the process of updating my book "Electronics ...

We use a microcontroller without a second thought, in applications where once we might have resorted to a brace of 74 logic chips. But how many of us have spared a thought for how the microcontroller ...

With these mods, this circuit will last quite a long time, especially if you make things easier for the relay by turning off power to the motor before switching directions. It is simple and effective ...

The evolution of microcontrollers (MCUs) has significantly transformed embedded systems, shifting from simple, standalone processors to complex, multifunctional units that rival traditional systems-on ...
