Arduino Interrupts

Often when working on microcontroller projects you need a background function to run at regular intervals. This is often done by setting up a hardware timer to generate an interrupt. The interrupt triggers an Interrupt Service Routine (ISR) to handle the periodic interrupt. In this article I describe setting up the 8-Bit Timer2 to generate […]

Arduino Sound Part 3. Playing a Melody

This is the third in a series of articles about generating sound with an Arduino. In this article we bit-bang our way through Jingle Bells . It’s almost Christmas so why not make a festive microcontroller project?
If your not up to speed on making sound with the Arduino read the first two articles in this […]

Arduino Sound Part 2: Hello World

This is the second in a series of articles about generating sound with an Arduino. The first article covered the various methods available for sound generation with an Arduino. In this article we take a small step; “Hello World” for Arduino sound. We prepare for our future experiments by hooking up a PC or […]

Arduino Sound - Part 1

This is the first in a series of articles about generating sound with an Arduino. The goals are to generate good quality sound which can be used to play simple tones, stored music, sampled sound, and even act as a MIDI synthesizer. I will cover the basic design, including code and hardware that anyone can […]

Arduino AVR In System Programmer (ISP)

Randall converted an Arduino into AVR chip programming hardware for use with AVRDude. The project programs AVR tiny13 and other tiny AVR chips using an Arduino. He provides code and instructions to implement the Atmel AVR910 In System Programming protocol.
This article was submitted by Randall Bohn as part of the “Hobby parts for articles” program. […]

Oscar does Arduino POV

Oscar Gonzales has done some neat things with the Arduino, this time he has a Persistence Of Vision (POV) project featuring the Arduino. He has a very well done video showing the details of construction and demonstrating operation. One really neat feature he has included is an IR trigger to keep the LED flashes necessary […]
