There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.

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 soil moisture meter is used to indicate the water content of a given soil sample. As crop production requires water at different stages and in different amounts, it is important to measure soil ...
