Building a DIY Digital Voltmeter with Arduino: A Beginner’s Guide

Creating a straightforward digital voltmeter with an Arduino and a 16×2 liquid crystal display (LCD) is a straightforward process. Measuring voltages with an Arduino is relatively uncomplicated. The Arduino provides multiple analog input pins that link to an internal analog-to-digital converter (ADC). The Arduino ADC, which is a ten-bit converter, produces output values ranging from […]

LED Microcontroller Debug Module

LED Microcontroller Debug Module

When it comes to debugging a microcontroller circuit, there aren’t a lot of simple options.  Since a microcontroller circuit might have multiple things going on at the same time, measuring voltages with a DMM isn’t an option.  Using an computerized In-Circuit-Debugger solution is expensive and elaborate, and time-consuming to set up.   People often resort to

AC Dimmer Circuit 1

AC Dimmer Circuit

Overview Simple AC Dimmer circuit for incandescent bulbs. 128 levels of brightness. Parts are relatively cheap! How it Works This is an AC Chopping Circuit. The dim level sets where the AC waveform gets chopped on. More of the cycle makes the bulb brighter, less is dimmer. (from digikey http://www.digikey.com/ca/en/techzone/lighting/resources/articles/Retrofit-LED-Bulbs-and-Drivers.html) Photo Digital Signals. The four
