Today I’m going to present some of more advanced capabilities of ADC built in ATSAM3X8E – the heart of Arduino Due. I like the Arduino platform. It makes using complex microcontrollers much simpler and faster. Lets take for example the analog-to-digital converter. To configure it even on Atmega328 (Arduino Uno/Duemilanove) you must understand and set […]

Overview In this lab, you’ll learn how to connect a variable resistor to a microcontroller and read it as an analog input. You’ll be able to read changing conditions from the physical world and convert them to changing variables in a program. (:toc Table of Contents:) Parts For this lab you will need to have

Have you ever struggled with audio settings in control panel in middle of a VoIP call? Or, wondered if the other guy can hear you properly? I have. My work requires great deal of remote conference calls using PC. The first thing I wonder always when starting is if my audio settings — mic volume,

For some strange reason I have a fascination with various types of electronic clocks (which explains this article). Therefore this project will be the start of an irregular series of clock projects whose goal will be easy to follow and produce interesting results. Our “Clock One” will use a Freetronics Dot Matrix Display board as
Clock One – Digital plus Analog Clock An Arduino Read More »
This week is all about analog inputs for the Arduino. I’ll show you how you can use a voltage divider circuit (see episode 3) and a variable resistor to make an analog sensor. We’ll also use a Sharp IR distance sensor as an analog input to detect distance and movement (with some clever programming). By

Have you ever wanted to use a good old knob to control your TV volume instead of repeated button pushing? Or make it controlled by light? Do you want your remote to be replaced by an awesome arduino and let it do the hard work of using a remote for you? Well this instructable is
Control TV functions using Analog input and Arduino Read More »
ow my Arduino can precisely measure audio input (VU meter), and obviously, next thing that comes to mind right after measurements, is regulation or control. There are many different ways how to electronically adjust audio volume or level of AC signal. I’ll name a few: Specifically design IC, Digital potentiometers. Mechanical potentiometers, driven by servo
