This project is designed to test the speed of the DAC (Digital-to-Analog Converter) and ADC (Analog-to-Digital Converter) on the Arduino UNO R4. Open the R4_DAC_ADC_Speed_Test.ino file in the Arduino ...

int voltage_0 = adc_value_0; //12bit ADC 除4096, 10bit ADC 除 1023//float voltage_0 = adc_value_0 * (3.30 / 4095.00) ...

[Simon Monk] got frustrated with bad ADC performance when tinkering with an ESP32 board, and decided to put three of the nowadays-iconic boards to the test – a classic ESP32 devboard, a Pi Pico with ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...

Abstract: The guitar is a highly popular musical instrument. Tuning a guitar can be challenging for many, prompting the need for research into developing an automatic tuning tool. This device utilises ...
