Paul McWhorter arduino lesson 35

 


 
We really learned how to run the computer from the linux command line from the terminal window so that you probably pretty feel familiar here with linux. What we showed more recently is you actually can boot the Raspberry Pi in a graphical user interfaces. So now that we know Linux now that we know how to operate from our friend the command line and the terminal window, we can sort of see yeah there’s a few things that are nice about a graphical user interface. We can always get back to our terminal window by clicking on that button, but what I want to show you today is: I want to show you how you can actually get something that’s very similar to Microsoft Office, but you can get a free version that will Do most of the things that office will do for the Raspberry Pi? How do we get it? We come to it’s called Libre library office, and so we come to the terminal window and we go sudo and then we go apt get install and then we go. If I spell this right well, I’d, be our e o FF IC e, like that boom looks like it’s reading it it’s probably going to take, and it says, do you want to continue yeah, I want to install it. I wouldn’t have asked it for it. I didn’t want to install it, but it’s it’s, like 300 megabytes, so it’s going to take a little while so just click yes and then go get yourself a cup of coffee and then we will start again.

We are back, and hopefully you are installed. It took took about 15 or 20 minutes here for it to get installed, but it’s a pretty big package right it’s got quite a bit of stuff in there. So so you can see here that everything looked like it went well and now we can close our terminal window and if we did this right, if we look under menu, we should see something that says office. We come down to office and look. We have office base, ok, manages databases calc, which is like a spreadsheet draw which lets you edit drawing flowcharts logos. So you can kind of draw things with it. I don’t even know if, if Microsoft Office has an equivalent of that, we have impressed create and edit presentation. So that would be like your PowerPoint and then library office writer would be like a word processor, so let’s just kind of click around on some of these and see what we got when I open this up. This is the word processor, let’s, just sort of kind of get a quick look at the look and feel of it it’s a little bit slower, probably the first time you open it after this, I think it gets a little bit a little bit quicker too. A little bit quicker to open, but look at this this looks very familiar. So this is my document and I come in and I can select over it and I can Center it and I can make it larger and I can make it bold.

Look at that. Okay and then I’m going to go back, I like to do that. Can I make a bulleted list let’s see where one of these is it? Oh look at this. Yes, I have a bulleted list. Okay – and you can see this needs to be run a little bit – bigger you’re, getting a little a little aliasing room, the on the the thing because I’m running running it remotely, but you can see that looks really good. I am impressed with this. I am very happy with the features it looks like I can do all the things that I’m familiar with. I can format I can insert I can view so. This is very very familiar to those of you who have used office products and so let’s close that discard, ok, let’s come in and let’s look at let’s look at calc because I think a lot of times. We need to use spreadsheets let’s, see what what this looks like it’s a spreadsheet right now, okay, again looks very familiar. Let’S say I come up here. I wonder if yeah I can zoom in look at that that’s. What I want to do get that bigger okay. So let’s say these are my grades. Okay, make a hundred, and then I made a hundred and then I’m a hundred and and I made 95 I made 97. So I had some good grades and then let’s say I can put here let’s see if it recognizes like the equal sign equal.

Yes um, okay, so I bet I can do a sum of my grades. There and I’m sorry let’s see some and then put it there and see if I can just drag and drop of that look at how easy that is boom. I can put your total okay that can put here average or if it has an average function, equals a V average. Just look at that it’s gon na maybe be rhe that’s a help. I guess, and then we come down didn’t want to do that. So you come down like that and then close it both what CI PI came down too far as to an average. We do that down to there boom. My average is a ninety eight point four, so this looks like a pretty full featured spreadsheet. Let’S see, if I can do some yeah, I mean yeah. I can do bold, so I can. I can change the color. I can let’s see font colors. I can change the font colors okay, so this is really a. This is really a full featured full featured stretching and the price is right. Okay, so let’s close that discard let’s take one more look: I’m, not much of a database guy. So I don’t want to look at the database, but let’s look at impress. This looks like kind of a PowerPoint equivalent yeah look at that my grasp very high blessings. Okay, so it looks like everything looks very familiar. It looks like we, I mean 35 for a Raspberry Pi and find an old monitor somewhere, and you can do in just about anything that you can do on a full blown that’s top computer, which makes me start start wondering.

Why do I need a full blown desktop computer? Why do I need to keep going back in thousands of dollars after thousands of dollars every year, buying a new one? Okay, let’s look here. I don’t know what this first one is let’s just see. If that does anything, oh okay, this just gives you a selection of things that you could go. You could go into know what this formula does. Maybe that lets you it’s a formula, editor that’s, actually very, very useful if you’ve ever tried to kind of do math in a word, processor it’s, pretty it’s, pretty poor, so it looks like it’s got a nice formula editor, so I will say thumbs up on this. This is a great free product, so the kind of things like I want to get just the minimum stuff that I need not a lot of chunk on the Raspberry Pi. But what I want is, I want a good browser, so I showed you in the last lesson how to install Chrome and then I want something where I can do some word processing and some spreadsheets I’ve got the Libre Office on there now and so probably in The next lesson, we’ll just show you a couple more a couple: more tricks to make this run a little bit. You know, run real, smooth and easy. Okay, Palmer quarter top tech boy comm. If you like this, give me a thumbs up. Think about sharing the video subscribe to the channel.

We’re opening the Arduino IoT Cloud to other platforms, starting with the ESP8266 by Espressif Systems — NodeMCU, SparkFun’s ESP Thing, ESPDuino, and Wemos (to name a few) — along with other inexpensive, commercially available plugs and switches based on this module.

  1. Hello dear Paul and thank you for your series of R.P. videos. I am a new persone to the R.P. world and are very pleased in learning about the. My work is in the tourist sector and are working as a Tourist Guide, unfortunately we are facing over 35% increase in inbound of tourists to Iceland. So I am looking for a way to change my into to a digital Tourist Guide. And have found the R.P. to be a very interested tool for that. Have you done any video about who to control 100 to 200 R.P. which can be installed at a different hotels with tour guided videos for the tourists. Looking forward to hear from you. Regards Hermann Valsson in Iceland. herman.valsson@gmail.com

  2. Paul-

    Is there a way to either launch a saved Libre Office document from the CLI or view it without the crypted view using the “cat” command?

  3. One question. All the formulas that I’m going to use on libra are the same as on xcel? I’m thinking to change from xcel
