You don’t see them much anymore, but there was a time when any hobbyist who dealt with RF probably had a grid dip meter. The ...

Abstract: Frequency measurement is crucial in electronic measurement, and digital frequency meters are essential for engineering. Their use in smart appliances increases demand for wider ranges and ...

Abstract: The key problem of the design of frequency meter is to how to rise to measure frequency precision, this paper put forward a high accuracy and wide frequency band frequency meter design based ...

This is a breadboard friendly breakout board for the Maxim MAX30105 reflectance, particle, and pulse ox sensor. This library should work with other MAX3010x sensors including the MAX30102, MAX30101, ...

This project is a frequency measurement tool based on the Raspberry Pi Pico and the RP2040 microcontroller. It uses the PWM hardware to count edges on two input signals—one is the test signal, and the ...
