Shadowandy’s Arduino-based Dust Sensor project: Put together a dust sensor using Arduino Mega 2560, Shinyei PPD42NS dust sensor and LCD shield. The codes and wiring instructions for Arduino Mega 2560 and Shinyei PPD42NS is as follow. However, I did include Serial output so you can view the sampling results using Arduino IDE’s Serial Monitor (9600 […]

Arduino-based “Analog” slow cooker controller
Dan Ternes blogged about his Arduino-based controller for analog slow cookers: With the AC power control figured out, I considered the User Interface. I opted for something simple. The Adafruit RGB LCD Shield would work well as it had both a display and buttons built in. Sure, I could have beat this project about the […]
Automatic feeder mod makes cat work for food
Here’s a cool automatic feeder for your cat that dispense food in exchange for a wiffle ball by Benjamin Millam. He wrote a post on his blog detailing its assembly: I used an Adafruit RFID reader to detect RFID tags embedded in the wiffle balls: the balls are cut slightly, enough to slip in an […]
ESP8266 Arduino NetIO Server demo
Peter Scargill writes: This week as regular readers know I was far away from our little home in Spain – in fact I was at MIT (Massachusetts Institute of Technology) in Boston, helping promote ESP8266 technology (why? because I could). Along the way I met up with Ivan Grokhotkov who as some of you know […]
Irrighino, a complete watering system based on Arduino Yun
Here’s Luca Dentella’s new project Irrighino, a complete watering system based on Arduino Yun. It features a user friendly AJAX interface and a fully-customizable open source firmware. The main features are: -a configurable number of solenoid valves -an AJAX web interface -a weekly schedule -manual activation / deactivation An Arduino Yun – the “brain” of […]
NExuS project
Adam over at Maniacal Labs has written up documentation on his NExuS weekend project: My main desires for this build was that the NES look completely stock and unchanged from the front and that original, unmodified, NES gamepads worked via the original gamepad ports. Fortunately, this turned out not to be too bad. First, I […]
2.2 or 2.4 or 2.8 inch SPI TFT LCD ILI9341 to Arduino Uno
Bob Davis has written an article on interfacing a 2.8 inch SPI TFT LCD ILI9341 with the Arduino Uno: Over the weekend I figured out how to interface a 2.8 inch SPI TFT that has a ILI9341 chip to an Arduino Uno. All it takes is eight 1K resistors. Most people use a 4050 IC. […]
6 Volt 5 Watt solar charge controller
Steve made this 6 volt 5 watt solar charge controller project, that is available at Github: Here is a 6 volt 5 watt solar charge controller project using a dedicated printed circuit board from dirtypcbs.com and an Arduino pro-mini. The board uses sot-23 low RDSon P channel mosfets (Si2369). It has voltage and current sensing, and 3 […]
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 […]

Eric of ElectronicHamsters wrote an article detailing his Uber home automation project: garage door sensor, battery powered mailbox sensor or door monitor, multi sensor, laundry room washer-dryer notifier, prototype of dog tracker, garage genie and remote control, smart mouse trap. Project info at ElectronicHamsters project page. Check out the project instructables here.
Nokia phone Arduino shield
Charles Pax is making an Arduino shield for the old Nokia phone: The cheapest and most common old phone we’ve seen is the Nokia 3100. There’s no camera, no Bluetooth, no WiFi, no frills at all. Perfect! We can pick it up in the market for just a few dollars. This is a pretty old phone […]
ESP8266 WiFi touch screen thermostat
An instructables on how to build WiFi touch screen thermostat by EasyIoT: In this tutorial we will show how to build WiFi controlled thermostat with ESP8266, Arduino and touch screen display. Thermostat will also show other info, like weather forecast and temperature outside. Total cost for thermostat is about 40EUR, which is price for basic commercial thermostat […]
Arduboy – card sized gaming
The final Arduboy, an Arduino gaming and learning project, came out yesterday. Kevin has been in Shenzhen arranging manufacturing for the last few months. He’s also been a staple at the neighborhood BBQ place and Hacker Camp after parties, some of us even got access to pre-release dev-kits. Of all the project builds I’ve witnessed […]
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 […]
How to develope for the ATtiny85 without becoming insane
Lembke writes: I like the ATtiny85. It is small, comes in a solder friendly DIP 8 case, has 8k Flash + 512 Bytes Ram, 5 to 6 IO pins at 8 MHz with no external parts. But developement is a pain: no serial (ok, it is possible but needs ports) and debugWire is even more […]
Dual port serial terminal
Piotr writes, “When developing communication between Arduino and ESP8266, I wanted to spy both lines of serial port. I was unable to find the right program on the web, so I made one myself.” The task is simple. I want to the spy serial communication at both lines at the same time. The hardware is […]
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 […]
DirtyPCB Arduino business card
Here’s an instructable by ProtoG on how to make your own PCB business card: In this instructable I am going to show you how to make your own printed circuit board business card.
