An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

This ESP32-based smart energy monitor can predict your next electricity bill. It tracks voltage, current, temperature, ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

Chris Gammell wants to know: What’s in your circuit toolbox? Personally, mine is somewhat understocked. I do know that in one of my journals, probably from back in the 1980s, I scribbled down a ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

The 0- to 20-mA current loop isa reliable means of data communicationin industrial applications.These circuits use a precision shunt inthe receiver to convert the current signalinto a voltage signal.

Selecting the right microcontroller for a product can be a daunting task. Not only are there a number of technical features to consider, there are also business case issues such as cost and lead-times ...
