    Suspense Courtesy of Arduino, Mess of Wires

    The ticking clock on the bomb is a Hollywood trope that simply refuses to die.

    if you’d like to build a dramatic prop and are mature enough to do so responsibly, [Giorgio] has the guide you need.

    The build is a straightforward one, relying on an Arduino to run the show. This is hooked up to a classic 7-segment LED display, upon which the countdown is displayed. For extra flair, an MP3 player is fitted to play the Mission Impossible theme.

    Arduino One Pixel Camera Sees All (Eventually)

    this single pixel camera built by [Tucker Shannon] is anything but normal.

    At the heart of his unusual camera is the TCS34725 RGB color sensor from Adafruit which receives a tightly focused beam of incoming light by way of a 3D printed enclosure and a 3mm OD aluminum tube. This allows an Arduino Uno to determine the color of this tiny slice of light, making up a single pixel of the final color image. [Tucker] notes that you could even swap the color sensor out for a simple photocell if you don’t mind a black & white image at the end of the process.

    RGB Control with Mobile App © MIT

    Control RGB LED with a slider in simple mobile app. Uses a very, very simple message with TCP connection between Arduino and mobile app.

    Simple Record and Playback © CC BY-NC-SA

    Record and play back a few seconds of input stored in EEPROM.

    This project allows you to “record” sensory input and store it for later use. The information is stored in EEPROM instead of dynamic memory so that it can be remembered even when the board is shut down (like a tiny hard drive).

    WerkTag Releases Adaino Data Acquisition Library for SAM D21-Based Dev Boards

    Swiss-based creators of open source hardware/software Werktag have recently released their Adaino analog data acquisition library for SAM D21-based development boards, which the company claims simplify reading analog inputs at any sampling rate. Adaino’s feature set includes reading and configuring analog inputs, real-time acquisition of data with no samples lost at higher rates, offers an intuitive API, and is entirely open source.

    Stomping On Microcontrollers: Arduino Mega Guitar Effects Pedal

    Effects pedals: for some an object of overwhelming addiction, but for many, an opportunity to hack. Anyone who plays guitar (or buys presents for someone who does) knows of the infinite choice of pedals available. There are so many pedals because nailing the tone you hear in your head is an addictive quest, an itch that must be scratched. Rising to meet this challenge are a generation of programmable pedals that can tweak effects in clever ways.

    With this in mind, [ElectroSmash] are back at it with another open source offering: the pedalSHIELD MEGA. Aimed at musicians and hackers who want to learn more about audio, DSP and programming, this is an open-hardware/open-software shield for the Arduino MEGA which transforms it into an effects pedal.

    Schindler Technologies Uses Arduino for the Pilot Remote Control

    Schindler Technologies recently launched their Pilot Remote Control powered by Arduino, which will allow you to control drones, RC vehicles, speakers, or anything else under the sun that can be operated wirelessly.

    remote was designed to work with either Nordic’s standard nRF24L01 2.4GHz RF transceiver/synthesizer module for ranges of up to 100 meters, or the nRF24L01+ extended module, which increases the distance to up to 1,500 meters
