Next with the provided link board files (dan.drown.org) (using the Arduino IDE 1.8.9) I got an ADC value of 2050 of 4096 which is about 50%. But, using the board files available here (v1.6.1), I only ...

I am currently trying to use the LL libraries to configure the ADC in Arduino IDE 1.8.9, but there is an error in the initialization of the LL_ADC_InitTypeDef Function when compiling: ...

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...

Most microphones’ output signals are weak and cannot be directly connected to some other circuits. Also, some microphones require DC power supply or high impedance inputs. Here is a dual (stereo) ...

What is a Successive Approximation ADC? Successive Approximation ADC is the preferred choice for low-cost, medium to high-resolution applications. SAR ADC resolution typically ranges from 8-18 bits, ...

A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it ...
