It has a remarkably user-friendly interface, a top-notch feature list, it works on all major platforms, and with the decently priced Pro version, you can also transfer files to and from some of the best cloud services.Like FileZilla, FireFTP supports FTP, SFTP and FTPS connections. If you're relying on FTP to transfer files, then you can't really go wrong with FileZilla. The supported cloud providers are Amazon S3, Blackblaze, B2, Box, Dropbox, Google Cloud, Google Drive, Microsoft Azure, Microsoft One Drive (and OneDrive for Business), Microsoft Sharepoint, OpenStack, Swift, and WebDAV. Up until now, all of its features were absolutely free, but recently there have been some important upgrades to FileZilla, and hence, FileZilla Pro is also something you should consider.įileZilla Pro aims to make FileZilla the prime app for all-things-file-transfer-related, in short, you can now transfer files between your PC (or Mac) and remote servers as well. More is better - FileZilla ProįileZilla is still an open-source app after all these years and continues to be one of the most trusted apps in this particular niche. Other noteworthy features include support for filename filters, directory comparison, HTTP/1.1, SOCKS5, and FTP-Proxy support, IPv6 support, and synchronized directory browsing. This way you can pretty much fully hide your IP during the transfers.Īnother great feature is the ability to transfer and resume very large files of well over 4 GB, quite useful for Internet connection downtimes or other unforeseen events that might occur. ![]() The app also allows you to search for remote files and even edit them remotely, as well as connect to FTP via VPN if you really need to. Better yet, you can configure the transfer speed limits for each instance of the transfer. You can also limit the number of simultaneous server connections from the Transfer menu. It can also run multiple server transfers at the same time, making it perfect for batch-transfer operations. SFTP allows files in transit to be "hidden" under an encrypted secure shell connection. To that end, FileZilla supports both FTP and SFTP (SSH File Transfer Protocol). One of the most important aspects of FileZilla is security, an aspect that's often overlooked by many FTP clients by default. Simple and easy to use, but not lackluster The beauty of FileZilla, though, is that it's easy enough for the average user, but also feature-packed to such a high level that appeals to the hardcore, advanced user as well. You can pretty much decide what happens with each transfer by simply right-clicking the entry. The panel below the file tree is where reserved for the file queue. ![]() ![]() The app boasts a familiar two-pane design that also features a drag-and-drop component, meaning that you can simply drag files from one panel to another to forgo transfers between your computer and the server and vice-versa with almost zero effort. ![]() The connection to a server can be set up in mere seconds, and once that's done, it's smooth sailing forward even for the least experienced users. Initially released on 22 June almost two decades ago, FileZilla started in life as a computer science class project and is the brainchild of Tim Kosse and two classmates.Ī big part of FileZilla's success has to do with its remarkable convenience. Thankfully, there are a lot of extremely competent FTP apps out there, but probably none more prominent and more popular than FileZilla, a name that's become almost fully synonymous with FTP transfers. When it comes to high-speed file transfers that go beyond just uploading or downloading a few small files, nothing comes close to a reliable FTP client or FTP application.

![]() How to write a serial 'handshake' between Arduino and Processing to control data flow.How to receive data from Processing in Arduino.How to send data from Processing to Arduino.How to receive data from Arduino in Processing.How to send data from Arduino to Processing over the serial port.Well, guess what - there is! - and this tutorial is going to show you how. A PString class at arduiniana can build strings from stream inputs, if strings instead of streamed output are desired or needed.So, you've blinked some LEDs with Arduino, and maybe you've even drawn some pretty pictures with Processing - what's next? At this point you may be thinking, 'I wonder if there's a way to get Arduino and Processing to communicate to each other?'. Note, Streaming.h doesn't build any strings as such it just delivers the text of its <<-arguments to a stream. Which would keep the longer string in PROGMEM instead of bringing it into RAM. This could also be written as Serial << F("Your coordinates are ") << _FLOAT(latitude,3) << ", " << _FLOAT(longitude,4) << endl For example, to print latitude and longitude values in a form like "Your coordinates are -23.123, 135.4567” one could write: Serial << "Your coordinates are " << _FLOAT(latitude,3) << ", " << _FLOAT(longitude,4) << endl One can write Serial within sketches where you use << as a stream operator.īase-conversion specifiers _HEX, _DEC, _OCT, and _BIN are provided, as well as a _FLOAT function (with number of decimal places) and endl. Serial.print(" Var 3:") Serial.println(var3) Serial.print(" Var 2:") Serial.println(var2) Using Streaming.h, in place of Serial.print("Var 1:") Serial.println(var1) So I added ESP8266 mention and a printf wrapper for common AVR modules As mentioned, it's not available on most of the AVR modules. \n is the escape sequence for the line feed.Įscape sequences are used to represent certain special characters within string literals and character literals. More details about formatting tips on the printf format reference page : No need for additional library or function. Its built-in in Serial class of the framework. Usage examples: p("Var 1:%s\nVar 2:%s\nVar 3:%s\n", var1, var2, var3) // strings Serial.print(buf) // Output result to Serial You can change the limit based on your requirements #include Ĭhar buf // resulting string limited to 128 chars The usage will depend of the data type of your variables. This is the function definition: #ifndef ARDPRINTFįor(i=0 str!='\0' i ) if(str='%') count Ĭase 'd': Serial.print(va_arg(argv, int)) Ĭase 'l': Serial.print(va_arg(argv, long)) Ĭase 'f': Serial.print(va_arg(argv, double)) Ĭase 'c': Serial.print((char)va_arg(argv, int)) Ĭase 's': Serial.print(va_arg(argv, char *)) It returns the number of arguments detected in the function call. The function prototype is: int ardprintf(char *. The output as expected is: test 2 123456789 g test 2.30 See it in action in this example:Īrdprintf("test %d %l %c %s %f", l, k, s, j, f) This function (given at the bottom) can be pasted in the beginning of the files where the function is needed. Ardprintf is a function that I hacked together which simulates printf over the serial connection. ![]() The brain can then interpret this offset as a binocular depth cue. This slight offset is termed retinal disparity. Due to the front-facing location of our two eyes, each eye sees a very similar, yet slightly offset image when looking at an object in space. The eyes must have a relatively similar image (this is why patients with lazy eye or strabismus have difficulty with stereopsis - the brain is working with dissimilar quality of images!). Stereopsis is the highest (most difficult) level of extracting depth information from the visual world. Flat fusion has no cues to depth - these are simple objects that look flat on a surface. Fusionįusion is the ability of the visual system to take two similar objects and combine them into a single object. The eyes must both move in the correct direction so that the visual axis of each eye is pointing at the same object of interest, and the images must be able to be fused. Binocular Depth Cuesīinocular depth cues are more complicated and required a coordinated effort from both eyes. Objects that are closer move across the retina at a faster velocity than distant objects when moving. ![]() Do you see the nearer finger moving faster than before? This is the parallax effect. Focus on your far away finger and rock your head left and right. What happened? Did you notice your finger moving slightly in the opposite direction of your head movement? Now keep your finger out at arms length and use your other hand to do the same motion, but at a distance closer to your nose. Look past your finger or thumb at a distant object and shake your head gently from side-to-side as if saying "no". Now hold your finger or thumb up at arms length away. Our visual system assumes light comes from the top-down of an object - changing how light and shadows appear on an object can change how the depth is interpreted. These are grouped together as light or shadowing of an object becomes a depth cue. The blue outline of an object against the sky gives a cue that the object is farther away. The "blueness" of the sky is due to scattering of shorter wavelength light (Rayleigh scattering). On a broader scale, we learn from young age that the earth is brown or green and the sky is blue. As you look into the distance, the lines appear to get closer and closer, which gets interpreted as the lines being farther away. Think of two lines that are parallel (lines on a road or railroad tracks are a good example). This is a fun drawing trick usually learned at an early age. Overlap (also called interposition) is a cue that tells the visual system that the front-most object is likely closer because it blocks the view of the back-most object. ![]() When a big object (say a car) appears small, you have a good idea that this isn't really a small car, but rather a car that is far away. ![]() You learned when looking around in the world that some objects are big and some are small. This is probably the easiest one to understand. Are you able to tell what items in the room are closer to you? Farther away? The answer should be yes! Even someone with one eye is able to use single-eye cues to depth. Cover one eye with your hand and look around. Take a moment to perform a quick experiment. What's very interesting about vision is that crude depth perception does not require the use of both eyes. You could also use the word "clues" for cues as these are the "clues" that tell the visual system about the 3D components of an object or space. These cues may be monocular (single-eye) or binocular (two-eye) cues to depth. Stereopsis (depth perception) is the visual ability to perceive the world in three dimensions (3D) - length, width, and depth - which then allows a person to judge where an object is relative to him or her.ĭepth perception arises from a variety of visual stimuli referred to as depth cues. ![]() ![]() You can find several other space themed songs here.Īlso, have you seen this whoopie pie solar system yet? Mmm. We loved singing our favorite rocket song (Zoom Zoom Zoom) as we worked on our projects today. Add extra pieces of cardstock (with glue) to serve as the fins at the bottom of the rocket.Ħ. ![]() I actually liked the cleaner look (without the marker lines), but kids always seem to like to add extra details, so I'll keep the markers as an option for the little ones I am working with tomorrow.ĥ. Use markers to draw in any details you'd like. Add other details to the rocket- buttons, foil, stickers, etc. Cut strips of tissue paper (great fine motor scissors skills activity) and glue them to the bottom of the rocket as the exhaust.Ĥ. Glue on the engine (yellow piece of paper in our pictures).ģ. Add the nose cone and body tube of the rocket and glue to the background paper.Ģ. Materials Needed: a few shapes (these were the basic ones we started with) cut out of cardstock, a piece of cardstock for the background (black or navy), scissors, glue, aluminum foil, stickers, jewels, buttons (other random items to add), tissue paper, and markers.ġ. You can never do too many rocket projects, right? While this might seem overwhelming, look at it from another perspective: collage frees you up from the rules of drawing or painting and allows you to explore your unique artistic language. The other version involved some painting and a cool window in the rocket with our favorite family members inside. With collage, there’s no limit on materials or approaches you use in image-making. this was the simpler version, so I thought I would share it. After stumbling upon this awesome art lesson blog ( Deep Space Sparkle) and the cool rocket collages, we had to try out our own rockets. |
