Juniper functional reactive programming language for Arduino

What is Juniper?

Juniper is a functional reactive programming language tailored specifically for programming the Arduino chip.

The purpose of Juniper is to provide a functional reactive programming platform for designing Arduino projects. FRP's high-level approach to timing-based events fits naturally with Arduino, with which programming almost entirely revolves around reacting to realtime events. Additionally, since C++ is a very low-level language, Juniper is intended to have better readability on a higher level. Juniper transpiles to Arduino C++, which is then compiled to an Arduino executable.

We designed this language because we believed that FRP was better suited for the Arduino’s problem space than C++, thanks to its alternative style and methodology of coding.

Arduino Uno vs BeagleBone vs Raspberry Pi

First, the Arduino and Raspberry Pi and very inexpensive at under $40. The BeagleBone comes in at nearly the cost of three Arduino Unos. Also worthy of note is that the clock speed on the Arduino is about 40 times slower than the other two and it has 128,000 (!) times less RAM. Already, you can see the differences starting to come out. The Arduino and Raspberry Pi are inexpensive and the Raspberry Pi and BeagleBone are much more powerful. Seems like the Raspberry Pi is looking really good at this point, however, it’s never that simple. First, its price isn’t quite as good as it seems because to run the Raspberry Pi you need to supply your own SD Card which will run you another $5-10 in cost.

Meet MariaMole, an Arduino IDE for advanced developers

MariaMole is an open-source project being developed by me, on my spare time. But it's already fully functional. Check some of its features:

• Runs over Arduino install: MariaMole uses the Arduino software that you have installed, so all your Arduino configurations are kept. You can still use the original Arduino side-by-side to MariaMole, if you want,.
• Workspace support multiple projects at the same time. Workspaces are special folders where you can group any number of projects. This helps you keep the projects organized, and allows working with several projects at the same time. If you have used Visual Studio, CodeLite, Code::Blocks, Eclipse or any other modern IDE, you know that this makes a difference. Specially if you're designing a system with multiple Arduino boards talking each other, you're gonna love the workspace feature!
• Multiple serial port consoles at the same time: And more: Once you open a serial console, it's always available. You don't have to close or re-open it again to upload your project to Arduino
• Files use open-formats: All project informatio and configuration are stored on a single XML file (Except for code!)
• Building process configurable: The Arduino IDE does a great job behind the scenes, but, sometimes, you're gonna need to fine-tune the building sequence, add or replace libraries or change the compiler options. Of cource, unless you ask for it, MariaMole works the same way as Arduino, building the whole project for you.
• Imports Arduino examples and sketches: You won't have any problems to reuse your old sketches.
• Easily import Arduino libraries: A Wizard windows helps you with that. And also with adding new files to projects, importing other files, configuring the projects, etc.
• Color-themes: Do you prefer a dark color-scheme for code editing? No problem. This is the default for MariaMole. Or do you prefer writing your code against a white background? No problem yet! MariaMole comes with a light theme too. And you cand design your own theme!

Of course you may ask "Why another Arduino IDE?". Well, I recomend checking this answer and others at the FAQ below:

PS.It just have PC version.

Introducing Raspbery Pi à la mode (Connect Pi to Arduino)

Here are the features including a few extra goodies:

• Flexible power. Can be powered directly from the Pi, standalone with a battery or wall-wart, or USB power. This is important if your shield takes more power than the Pi can provide or if you want to undock it for standalone operation.
• Programmable via the Pi’s UART on the GPIO pins, or an FTDI USB-Serial adapter or ISP.
• Header for connecting Fastrax UP501 GPS.
• DS3234 Real time Clock. The Pi doesn’t have it’s own battery backed RTC. You can set a program in the AlaMode to report the time to the Pi via serial or I2C
• Micro-SD card slot. Useful for datalogging, and big-memory  for your Arduino applications
• Row of Servo Headers connected to the PWM pins with a configurable power and ground rail

Arduino Simple Task Scheduler

Get the code here: https://github.com/Zuph/AVRQueue

Introducing the Arduino Simple Task Scheduler.  This is part of the balloon flight computer code I wrote for White Star, with some more polish. This library allows you to create a schedule queue of functions to be executed at specified times, on specified intervals.  For example, say you’re trying to log some sensor data and update a display in the same program. With the task scheduler, you can simply write a function to gather sensor data, write a function to update the display, add them to your queue, and let the library handle the rest.

OpenWRT router interfaced to an Arduino

So far the nicest solution I have found is one of the world’s smallest pocket routers TP Link WR703N.
Cheapest in price 25 USD, nice looking 5x5x2 cm plastic box, internal Wifi. Can be ordered on Ebay, shipping is free and it arrives from HongKong in a month.  This router has a 400 MHz CPU, 4 MB flash (quite small),  32 MB RAM, 1 Ethernet, Wifi, 1 USB, 0.5 W power consumption. Powered via USB cable. Included power supply can be plugged in 110V or 220V.

It must be reflashed with OpenWRT Linux, where most necessary program modules exist, however not everything is compatible with Debian Linux. Can add USB hub, USB stick, USB sound card, bluetooth, webcam, 3G modem, 1-wire USB or serial module, connect to Arduino, set up Wifi client, place home webserver on router.

Bloom Serial Port to TCP/IP Socket Redirector for Microsoft® Windows®

Bloom for Microsoft® Windows® is a serial port to TCP/IP socket redirector. Its role is to transfer data from a serial port to an open TCP/IP socket connection, and vice versa. Bloom facilitates full-duplex communication with any serial device over a network connection from any application that can open a TCP/IP socket.

The concept is illustrated below. Here, Bloom has been installed on a host machine to which several serial devices (both wired and wireless) are connected. Bloom accepts incoming TCP/IP socket connections from several remote machines and redirects all incoming network traffic received over each TCP/IPsocket to the corresponding serial port. In turn, all data received on a serial port is redirected back to the corresponding TCP/IP socket, emulating a direct physical connection between the remote application and the serial device.

Arduino and the Web using NodeJS and SerialPort2

Using the USB, the Arduino Board is connected to the PC serially to a certain COM port which the OS allocates. Node.JS, the asynchronous server side JavaScript engine then listens for the port using a Node.JS module called SerialPort2. When a signal is received, using the Node.JS Socket.IO module, data is then served also asynchronously to the web providing a real time feed of the Arduino signal.

The following are the key technologies being used to present the feasibility of this approach to the particular problem:

• Arduino - A small electronics prototyping board. Available in multiple versions but in this article the one being used is the Arduino Mega 2560 Version 1. The same methods can be applied to other versions of the Arduino as long as it has means to output data serially.
• NodeJS - A server side JavaScript interpreter.
• NodeJS SerialPort2 - A Node.JS module for listening to COM ports.
• NodeJS Socket.IO - A Node.JS module for serving async data to the web using technologies such as WebSockets.
• NPM - Is a Node.JS package manager already included with the official installer of Node.JS.
• jQuery - A JavaScript library for easier scripting.
• Flot - Flot is a pure JavaScript plotting library for jQuery.
• Apache - Used in this project for serving static content. The WAMP pack is the suggested package for easy installation. The user can also use the WAMP pack for hosting PHP and MySQL.

For Windows users, SerialPort2 requires the following for a successful build:

• Python 2.7.3
• Visual Studio 2010
• Windows SDK 7.1

The Making of Arduino

The little board is now the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. More than 250 000 Arduino boards have been sold around the world—and that doesn’t include the reams of clones. "It made it possible for people do things they wouldn’t have done otherwise," says David A. Mellis, who was a student at IDII before pursuing graduate work at the MIT Media Lab and is the lead software developer of Arduino.

NXT Shield Version 2

NXT Shield. The big news is that it now supports the Lego Ultrasonic Sensor and it has NXT Compatible Sockets from mindsensors.

http://blog.tkjelectronics.dk/2011/10/nxt-shield-ver2/

The I2C frequency has to be adjusted – the datasheet says 9600Hz, but I have adjusted it to 11494,253Hz, as it is the same as the one used by the NXT (measured with my logic analyzer).
For more information see this pdf, at “Input ports” and “I2C Communication”.
Furthermore if you have a look at the Appendix 7-LEGO MINDSTORMS NXT Ultrasonic Sensor I2C communication protocol, it says byte 2 is R + 0×03, this means that the user have to send a repeated start and read from the device straight away.
So for example if you want to read the product version. The official Arduino Library (Wire.h) doesn’t support repeated start. So instead I decided to use a modified version of Peter Fleury excellent library: I2Cmaster, as it can be used for any AVR devices.
The library is modified to work with the Lego Ultrasonic Sensor (I2C frequency set to 11494,253Hz), and the CPU frequency has been set to the one used by Arduino (16MHz). Keywords has also been added, so the commands will colored orange.

The modified library can be found here: i2cmaster library.

Lxardoscope is a Linux+Arduino oscilloscope

[Privatier] wrote in to let us know about lxardoscope, his project that lets you use an Arduino as hardware input for a Linux-based oscilloscope display. This implementation offers two channels with about 3000 samples per second from each. He touts some of the GUI options like vertical resolution between 2mV and 10V per division. That part kind of stumps us because we don’t see how a measurement of 10V (or more) can be taken using the schematic included. But you’re comprehension may surpass ours so do take a look yourself.
