    Badland Brawler Lets Arduino Tackle Terrain
    https://hackaday.com/2019/01/27/badland-brawler-lets-arduino-tackle-terrain/

    For an electronics person, building the mechanics of a robot — especially a robust robot — can be somewhat daunting. [Jithin] started with an off-the-shelf 4 wheel drive chassis to build an off-road Arduino robot he calls the Badland Brawler. The kit was a bit over $100, but as you can see in the video below, it is pretty substantial, with an enclosed frame and large mud tires.

    Arduino Serial Data Directly Into Microsoft Excel
    http://playground.arduino.cc/Main/Excel

    Although 3rd party applications and plugins are available for port logging, it is possible to log data directly into Microsoft Excel through Visual Basic.

    There are no lack of applications tailored towards saving a .CSV file from an open port, which can then be imported into Microsoft Excel. For instance, GoBetwino, Processing, and Eltima Port Logger are useful and implementable strategies.

    However, it is possible to have Visual Basic (underneath Excel) listen to the serial port and output the data directly into Excel without requiring another program or plugin to load – in both Mac and PC versions.

    For Excel in Windows:
    Visual Basic connects directly to the COM port.
    Setting a faster baud rate in the PC macro works well.

    For Excel in OS X:
    For the Mac version of Excel, things are a little more complicated.
    I was unsuccessful in using a baud rate other than 9600bps with the Mac macro, even with the stty command in the terminal window.

    Turn Arduino Sensors Into Long Distance Industrial Sensors with Industruino’s 4–20mA.ker
    https://blog.hackster.io/turn-arduino-sensors-into-long-distance-industrial-sensors-with-industruinos-4-20ma-ker-8bfa67572d63

    Industrino has unveiled their new universal 4–20mA sensor transmitter that allows you to take an Arduino-compatible 3.3V sensor and transform it into a long-range industrial counterpart.

    “The 4–20mA.ker is a universal Arduino derived 4–20mA sensor transmitter. It allows you to install 3.3V sensors in remote locations over a single pair of wires. This is achieved by transferring power to the sensor and data back to the receiver using a 4–20mA current loop.”

    Well-Loved Toy Turned Into Robotic Glockenspiel
    https://hackaday.com/2019/02/04/well-loved-toy-turned-into-robotic-glockenspiel/

    If there’s a happier word ever imported into the English language than “Glockenspiel”, we’re not sure what it is. And controlling said instrument with a bunch of servos and an Arduino makes us just as happy.

    When [Leon van den Beukel] found a toy glockenspiel in a thrift store, he knew what had to be done – Arduinofy it. His first attempt was a single hammer on a pair of gimballed servos, which worked except for the poor sound quality coming from the well-loved toy.

    The improved instrument was then outfitted with eight servos, one for each note, each with a 3D-printed arm and wooden mallet.

    This instructable’s aim is to teach people how to create a watering system from scratch.

    This is done by controlling the various factors that affect a plant’s growth through the use of a sensor and a smart mini-controller – such as Arduino Uno. By the end of this paper, you will be able to create a fully functional watering system for your plant.

    Arduino One Pixel Camera Sees All (Eventually)
    https://hackaday.com/2018/12/17/arduino-one-pixel-camera-sees-all-eventually/

    Taking pictures in the 21st century is incredibly easy. So easy in fact that most people don’t even own a dedicated camera; from smartphones to door bells there are cameras built into nearly electronic device we own. So in this era of ubiquitous photography, you might think that a very slow and extremely low resolution camera wouldn’t be of interest. Under normal circumstances that’s probably true, but 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

    DIY Six Channel Arduino RC Transmitter

    But what if even cheap hardware running customizable software isn’t enough? What if you want to take it to the next level? In that case, [Electronoobs] has an Arduino powered RC transmitter with your name on it. But this is no scrap of protoboard with a couple of cheap joysticks on it, though he has made one of those too. The goal of this build was for it to look and perform as professional as possible while remaining within the hobbyist’s capabilities. The final product probably won’t be winning any design awards, but it’s still an impressive demonstration of what the individual hacker and maker can pull off today with the incredible technology we have access to.

    Don’t Delay() Use an Arduino Task Scheduler Today!
    https://www.hackster.io/GadgetsToGrow/don-t-delay-use-an-arduino-task-scheduler-today-215cfe

    Task scheduling is a transformative way to write maintainable code for Arduino and other AVRs. No more spaghetti code. C++ tutorial.

    As my Arduino projects became more complex I started to realize the delay() function caused unforeseen problems. While in a delay, the Arduino/AVR can’t process any other code (with a few exceptions). I came across this solution while researching another topic and I thought I would document it for my future projects. Alan Burlison created an eloquent Task Scheduler library that solves the delay issues —but more importantly, it made me rethink how I design my Arduino/AVR projects.

    A very simple Arduino task manager
    http://bleaklow.com/2010/07/20/a_very_simple_arduino_task_manager.html

    The LED chain project I’m working on requires that the AVR microcontroller handles several different tasks:

    Read a rotary encoder and switch
    Drive a seven-segment display
    Drive a radio
    Drive four LED strips each containing twenty LEDs
    Provide logic to tie all the above together

    Normally that sort of multiple-task workload might suggest the use of a RTOS, but the Arduino Pro Mini has only 32Kb of program memory (of which 2Kb is used by the bootloader) and 2Kb of RAM, so every byte is precious. So, whatever we come up with has to be as minimal as possible. OK, let’s see if we can make some assumptions and trade-offs that will help keep things simple and create a small set of C++ classes we can use to implement the task management

    Use the program to manage your ESP module with simple commands. This will allow you to access the Internet for any Arduino product.

    This program solves the ESP module with only simple commands.

    Upload the esp code to your ESP module (help here)

    Upload the arduino code to Arduino

    Connect the Arduino digital port 7 with the ESP GPIO0 pin, which is labeled D3!!!

    Connect the Arduino digital port 8 with the ESP GPIO2 pin, which is labeled D4!!!

    If you are not using nodeMCU but ESP-01, you will need a Bi-Directional Logic Level Converter.
