An Arduino pulse sensor project from Bajdi: I found a little heart rate sensor @ ICstation. It is a clone of the open hardware pulse sensor. The sensor is well documented, and it comes with Arduino and Processing example code. To try it out I connected the sensor to an ATmega328 running at 3.3V and loaded the example Arduino […]

LittleBits Hue lighting controller
Jeremy Blum has written an article about his latest project the LittleBits Hue lighting controller: The LittleBits Hue Controller is an easy-to-setup, wall-mountable, physical controller for your Philips Hue lightbulbs. The controller makes it easy to turn the lights on/off, change their brightness, and cycle through preset colors. This is a great project for people who […]
Programming an Arduino via WiFi with the ESP8266
Gary Servin has been working on a new project a method to flash an Arduino via WiFi using the ESP8266. He wrote a post on his blog detailing the process: I’ve been working on a new robot called RoDI for a summer course at my Alma mater. RoDI is a low cost wireless robot to teach […]
Arduino-based inductance meter
Lukas of Soldernerd built a DIY Arduino-based inductance meter: I’ve just finished a little Arduino project. It’s a shield for the Arduino Uno that lets you measure inductance. This is a functionality that I found missing in just about any digital multi meter. Yes, there are specialized LCR meters that let you measure inductance but they typically […]
Using DS1307 and DS3231 real-time clock modules with Arduino
John Boxall over at Tronixstuff has posted a detailed tutorial on how to on how to use DS1307 and DS3231 real-time clock modules with Arduino: There are two main differences between the ICs on the real-time clock modules, which is the accuracy of the time-keeping. The DS1307 used in the first module works very well, however […]
ArTICam: Game boy camera photos with a graphing calculator
A Game boy camera photos with a graphing calculator from Cemetech: ArTICam uses the ArTICL library to connect a TI graphing calculator and a Game Boy camera. The Game Boy camera was an accessory released in 1998 for the popular Game Boy handheld gaming platform, allowing Game Boy owners to take photographs. It is built around […]
CNN coverage of Arduino, open source
In this article Peter Shadbolt, writer for CNN, introduces their readers to the world of open source through his description of the Arduino’s development. While there’s nothing there that Arduino users don’t already know, it’s encouraging to see mainstream news publications giving positive coverage to open source.
Self-Balancing Raleigh Chopper
XenonJohn posted detailed instructions of how to make this Self-Balancing Raleigh Chopper. He writes: Data from the IMU is read by the Arduino Mega 1280. I use a Mega 1280 because they are a lot cheaper online than the 2560, and about the same price as an Uno. They have several hard wired serial outputs which means […]
Arduino Library for Freescale’s MMA7361 3 axis accelerometer
Rohit Gupta wrote a basic library for using MMA7361 3axis Accelerometer with Arduino, that is available at Github: This library helps you to easily play with the almost universal 3 axis accelerometer available in most Hobby markets that is based on Freescale’s MMA7361. In order to get in working you have to pull-up the sleep […]
DIY lithium battery charger shield for Arduino
Abdulgafur Mujdeci over at Electro-Labs has published a new project a DIY lithium battery charger shield for Arduino: In this project, we are building a programmable single/multi cell lithium battery charger shield for Arduino. The shield provides LCD and button interface which let the user set the battery cut-off voltage from 2V to 10V and charge current from […]
Cat protector project
Here’s a cat protector project from LuckyResistor. Check out the project page from prototype to the final device: if you own a cat, you know even if your cat is well brought-up, laws are only valid as long you are at home or even in the same room. the goal of this project was to create […]
Introducing CT-UNO, Cytron version of Arduino UNO
Vincent informs us of this Arduino compatible CT-UNO, the Cytron version of Arduino UNO: The CT-UNO combines the simplicity of the UNO’s Optiboot bootloader (which load program faster), the stability of the FTDI and the R3 shield compatibility of the latest Arduino UNO R3. Besides, we know many are using Android phone which comes with USB micro-B cable […]
Introducing RFToy, an Arduino-compatible gadget for radio frequency modules
Ray Wang from RaysHobby has informed us of his latest open-source project called RFToy: It’s an Arduino-compatible microcontroller board for interfacing with radio frequency (RF) modules, such as the popular 433/315MHz transmitter/receiver, and the nRF24L01 transceiver. Recently, while browsing a tech forum, I stumbled upon a discussion about 카지노사이트, which caught my attention as it highlighted […]
SDWebServer – enc28J60 and Arduino
Luca Dentella has informed us of his latest project using an ethernet shield based on the ENC28j60 driver from Microchip. SDWebServer is a complete webserver that can retrieve static elements from an SD card (including a user-defined default webpage) and can also create dynamic pages. This is the latest post in my tutorial about using […]
LED matrices and MAX7219 ic’s
A 10 60mmx60mm Led matrices controlled by an ATmega328 + 10 MAX7219 ic’s from Bajdi Electronics: Made a big LED matrix this week using 10 60mmx60mm LED matrices. I designed the PCB’s myself and had them made in China. Every PCB has a MAX7219 and a header to plug the LED matrix in. The 10 PCB’s are […]
Portable bluetooth-enabled scrolling LED matrix display
An open-source cascadable 8×8 LED matrix module using Arduino and MAX7219 from Embedded Lab: Easy Matrix is a cascadable 8×8 LED matrix module with the MAX7219 chip on board, which allows to control the display with only 3 I/O pins from microcontroller. Multiple Easy Matrix modules can be easily cascaded to make a bigger-size display through […]
New MurchLabs TinyLoadr Shield
Jeff Murchison has released a new version of my TinyLoadr Shield, which was used for programming ATmegas and ATtinys using your Arduino. The new version is just a USBtinyISP-based programmer with a ZIF socket for DIP microcontrollers and 10 and 6-pin ICSP headers for programming target boards. More information can be found at MurchLabs. Via […]
Using the AS5048A angle sensor
Richard from Zoetrope wrote this blog article about a PCB to make using the AS5048A angle sensor really easy. He used dirtyPCBs for the board, and Zoetrope will be giving a few of them away. Via the contact form.
Using Arduino due’s true random number generator
Kerry Wong writes: Arduino Due uses an Atmel SAM3X8EARM Cortex-M3 CPU, which has a native hardware based True Random Number Generator (TRNG). In this post, we will take a brief look at how to use it in the Arduino environment and take a look at some of its statistical characteristics.
The LED chasing effect project using Atmel AVR microcontroller
rwb over at Ermicro writes: In this project we are going to use both the Arduino IDE and Atmel AVR Studio to program the AVR ATMega168 microcontroller, therefore you could learn to use these well known Integrated Development Environment (IDE) to program the project.
