Arduino time lapse – camera pan device

An Arduino camera pan device project from Bajdi Electronics: I own one of these small action cameras (SJcam SJ4000). I bought it because it’s small, and easy to take with you wherever you go. To make nice stable videos I mount it on a mini tripod. This got me thinking that it would be fun to have […]

Simple Infrared PWM on Arduino

The crew from AnalysIR has written up an article on Simple Infrared PWM on Arduino. This first part of a series will show you how to generate the simple Infrared carrier frequency on Arduino: We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a […]

Arduino measures heart beat rate from fingertip

Raj of Embedded Lab writes: The PIC16F628A based heart rate meter is one of the most popular projects published on Embedded Lab. In this article, I am going to show how to replicate the same project using a simpler platform like Arduino. The Arduino heart rate meter will use Arduino Uno, Easy Pulse Plugin, and 4-digit […]

Playing with analog-to-digital converter on Arduino Due

Piotr wrote a post on his blog about using some of advanced capabilities of ADC in Arduino Due: 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 […]

MozMo : the brilliant Arduino Mozzi synth in an Eurorack hardware

Jean-Luc Deladrière blogged about his MozMo build: Mozzi by Tim Barras is an outstanding library that allow the Arduino to produce complex and exiting sounds with almost no additional hardware. (In fact MozMo uses the hifi mode that requires … 2 resistors and a cap !) The idea was to build a dirty cheap modular synth exploiting […]

Easy Pulse Plugin, an Arduino pulse sensor

Raj over at Embedded Lab has written an article detailing the new version of their Easy Pulse Sensor: the Easy Pulse Plugin, an Arduino and chipKIT compatible pulse sensor based on Photoplethysmography Today we are happy to announce the release of a new addition to our Easy Pulse Sensor series named Easy Pulse Plugin. Like its predecessors, the original Easy […]

Arduino-powered turntable plays moon phases

While this turntable can’t play “Dark Side of the Moon”, it certainly can tell you which way it’s facing! This project by Yingjie Bei and Yifan Hu uses an Arduino to position a turntable and associated light source in such a way that the moon replica mounted on the turntable will be illuminated to demonstrate […]

ESP8266: Arduino compatible $5 MCU with WiFi

MAKE has posted Alasdair Allan’s three part series concerning the ESP8266 MCU. Alasdair highlights the capabilities and limitations of this chip, the installation and use of a supporting version of the Arduino IDE, and how to create a breadboard adapter for the ESP-01 breakout board (pictured above.) Via MAKE.

Arduino based high-altitude balloon tracker

Ugifer wrote this instructable detailing the build of his Arduino based high-altitude balloon tracker: The tracker is based upon the Atmel ATMeag328 Microcontroller which forms the heart of many of the popular “Arduino” boards. We are going to make an “Arduino Compatible” board which we can program using the Arduino IDE. Because the GPS module and […]

Arduino-assisted automatic 3D printed tea maker

If the earlier Arduino projects weren’t your cup of tea, try out this Automatic 3D Printed Tea Brewer. 24 Hour Engineer Brian McEvoy designed this project which uses the Arduino to control a servo which dunks the tea bag for a predetermined length of time for perfect brew control. The LCD readout provides information about […]
