[mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 chip that boosts the ...

Frequency meters measure repetitions per unit of time (frequency) and display it using a needle or graphic pointer. Industrial frequency meters are used in radio frequency (RF) and microwave ...

This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing ...

Customers in the north of England and Scotland could be missing out on the cost-saving benefits of energy smart meters ...

Energy UK, the body that represents energy industry, has confirmed that there is a regional divide in terms of how the energy ...
