Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

[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 ...

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 the ...
