    What can I do if the connexion was refused?? when I typed the IP adress?

    • ExplainingComputers

      Try again! Suggests a typo, or SSH not enabled on the Pi.

    Hi Chris, Been following this series, and am building my own. After trying to run PuTTY. I got a connection refused error. Fixed by turning the SSH option to ENABLE in the Raspberry Pi Configuration menu. From the Raspian desktop, Raspberry - Preferences-Raspberry Pi Configuration. Interfaces then enable SSH click OK and reboot. Then the Pi will work from PuTTY. Raspian was from NOOBS version 2.8.1 released 2018-04-24. Hope this helps others that have the same problem when following. Keep up the good work. Andrew D

    Really nice project, thanks a lot for sharing.
    May I suggest an alternative with Bonjour protocol to let the Pi announce itself on the network.
    That way, there are no more pain to reserve/maintain IP, just connect to, for example, zummo.local and that's it.

    Hi again Christopher - I'm trying to figure out how to get the keyboard control script (key_robot.py) to run when I start up my Pi. There seem to be a number of approaches, the only thing I've made any progress on is getting the terminal to load at start up via the startup file here: /home/pi/.config/lxsession/LXDE-pi/autostart. I have not been able to get the python script to actually run on startup. Is this possible? I thought I heard you mention it somewhere but I haven't been able to find the video. Thanks again!

    • ExplainingComputers
      ExplainingComputers  5 месяцев назад

      You have to run the code in a terminal window or it will not work, as the curses method of obtaining keystrokes does so from a terminal window (hence the error you get above). All I can say is that the method in my Devastator window works! :) Good Luck!

    • BobbleNoggin
      BobbleNoggin 5 месяцев назад

      The python script will run if I kick it off in a terminal window. but not if I try to "run" the file in a python window.

    • BobbleNoggin
      BobbleNoggin 5 месяцев назад

      Dang. I was doing pretty well and the terminal actually opened and looked like it was going to work, but I got no response form the keyboard. Now I'm getting "curses.error: setupterm: could not find terminal" even when I try to just run the script in a python shell. Not sure if I hosed something up or what, your change was pretty straightforward.

    Further question, you use a USB Power Bank, to power the Pi. What capacity is yours, plus how long can this keep the Pi operational? Could i use a single more substantial Power Bank, to run BOTH Pi and Motor board together (single power source for all components, plus no need for a bank of AA's)?

      Thank you for the reply but I already figured out and fixed the problem :)

    • ExplainingComputers
      ExplainingComputers  8 месяцев назад

      It could be a different Python version. And the Raspbian version may impact the libraries available, and whether you need to run with a sudo on the front to access GPIO.

    • Saattvik Thourwal
      Saattvik Thourwal 8 месяцев назад

      Can it be because of the different rasbian version ???

    are you still using ieee802.11g router in 2017?
    by today I have more ieee802.11AC cards then I ever had computers (60 odd cards versus around 50-60 computers), but I do sell those cards anyway
    anyway my least powerful computer (Raspberry Pi 3) would be bottlenecked by ieee802.11g and in fact ieee802.11n is a bottleneck for it anyway.

    I've been wondering about these exact subjects for so long now.. RasPi GPIO access, Linux, Python programming, SSH... this series has been an massive eye-opener for me... what a fantastic way to start a weekend!
    And oh, what a coincidence... the hexapod robot I've been building, with intentions of driving with 8-bit PICs, will perfectly fit a full-size RasPi.... oh, the world you've just opened.

    • ExplainingComputers
      ExplainingComputers  Год назад

      Thanks for this feedback. I hope that you enjoy the final part of the series -- posted last week -- where I turn the robot into a line follower. You may also be interested in my Raspberry Pi GPIO inputs video -- ruclip.com/video/NAl-ULEattw/видео.html -- which kind of completes the set.
      Your hexapod robot sounds interesting, and a great project to drive with a Pi! Good luck with this. :)

    Can't I do so I simply add a port in which the Router will try to avoid giving to other devices, but when a device on the network asks for that number it will happily give that free spot to whoever is asking for it. Because later on I would like to add more devices on the network with a static IP, so when I'm in the Router configs I can simply make 4-5 new spots all at once and then set the devices one at a time to their respective spot.
    A pre-selected spot for ANY device who has a matching static IP address on the same network but will avoid giving those spots to none static addresses, is this possible?
    And something completely different, you log in with your standard gateway to get to the Router config page right? I got a different number than yours, but I still cannot access the Router page through any browser I have installed (Chrome, FireFox, Explorer). You got any tips what I should look up to gain access? And I would love if you could do more hardware tutorials, stuff such as how to use and install a LCD screen (I got a Adafruit 16x2 cha. monitor who most people buy when they want to experiment with new devices), different buttons such as roll buttons you find at most console controllers, etc.

    if you install tightvncserver, you can use your Android tablet as screen for the raspberry pi (rasbian)

    sudo apt-get update
    sudo apt-get install tightvncserver
    tightvncserver
    it will ask if you want to make a view-only password. input "n"

    sudo nano /etc/init.d/tightvncserver
    type in the file:
    #!/bin/sh
    # /etc/unit.d/tightvncserver
    # Set the VNCUSER variable to the name of the user To start
    tightvncserver under
    NCUSER='pi'
    case "$1" in
    start)
    su $VNCUSER -c '/user/bin/tightvncserver :1
    echo "starting TightVNC server for $VNCUSER"
    ;;
    stop)
    pkill Xtightvnc
    echo "Tightvncserver stopped"
    ;;
    *)
    echo "Usage: /etc/init.d/tightvncserver
    {start|stop}"
    exit 1
    ;;
    exacte
    exit 0

    safe the file and return to the terminal.
    sudo chmod 755 /etc/init.d/tightvncserver
    update-cr.d tightvncserver defaults
    sudo reboot

    download VNC viewer
    open VNC viewer
    click on the +
    ip = ip + :1

    if you have reboot, tips in the terminal:
    tightvncserver

    open VNC viewer and connect

      One solution is to put in a time delay -- something like time.sleep(0.1) -- at the end of the while loop, then turn all motors off before the loop repeats.

    this is really interesting. i have an idea of taking an old RC car apart and placing the pi inside, then installing a cheap power bank. i would also install a cheap mini router so i have i can connect my android phone to it on the go. this is just an idea but i might not go through with it.

    • ExplainingComputers
      ExplainingComputers  Год назад

      You idea will work using the same config I show here if the car uses two motors. You will just need a motor control, like the L298N I use here to make hook it up to the Pi. I run through the set-up in the previous two videos in this series -- all info and wiring is here: www.explainingcomputers.com/rasp_pi_robotics.html Good luck! :)

    Very nice and complete tutorial.
    Just one thing. You do not need to hide your MAC, since outside visitors can see only the MAC of your router. The router normally replaces the MAC with its own. However, if you plan to use your robot outside your network, maybe hiding isn't a bad thing 😊
    I have tried to lock out hackers by MAC, but failed due to the mechanisms of routers.

    I purchased the 'Scratch Programming - In Easy Steps' book and have been working through it with my children. Towards the end of the book it introduces you to the Raspberry Pi and suggests that you continue from there. So I did a search for Raspberry Pi projects and found this; we've been following and enjoying your tutorials ever since. Please keep them coming, we can't get enough!!! :-)
    A couple of suggestions that we have sat and thought about.
    1. Would it be possible to purchase a basic USB solar panel and attach it to the top of our robot and have it charge the portable USB power bank?
    2. How about adding a Pan-Tilt HAT so that we can attach and control the Raspberry Pi camera remotely?
    We eagerly await your next video for this project.

    I always lock all my devices on my network via MAC to a reserved IP address. The DHCP Leases page on my router is normally where I go to find out the IP and MAC address quickly. I have two IPs reserved for my Pi3, one for the LAN and one for the WiFi.
    Have you thought about mounting a camera on it? Set the camera up as an IP camera for remote viewing and drive it using your Android tablet to areas where you can not actually see it.

    For instance pi robot over the web using dyndns (dyndns.net) and using appropriate port forwarding through the router to port 22 (changing pi user password to something better)
    Could you not connect through the hostname instead of IP? i.e pi@PiZeroZumo wouldve been a good alternative to show.
    + JuiceSSH
    is it not time for a router upgrade Chris? The DG834GT is very old.

      I realise my comment came across as slightly moany.
      Thats certainly not the case, I enjoy your videos and your presentation effort. I really like your old school values (If it ain't broke, dont fix it). Your tour around your desk was particularly great seeing as you are using an old tower from the 90's and just upgrading the hardware from time to time. The form factors don't change so utilise them.
      The DG834GT was my introduction to Wi-Fi when I was younger. No complaints from me, I just thought that a lot of people now will be using simpler routers from their ISP and reserving IP addresses are not as challenging (grabbing MAC addresses and such). With the DG834GT have you ever found the "firmware" hacks that you can get. I seem to remember having one that provided the ability to send out Wake-On-Lan packets across your network from the GUI.
      Thats said, I enjoy your videos please keep making them :).. and sorry for my waffled response.

      Yes, there is lot more I could have covered here. But I aim videos at those who do not know this stuff, and need think how much I can reasonably include in each video -- and this was already getting long. But I will get to other stuff! :) As for my router, old -- yes. But it has never given me any problems (touch wood!), so I won't replace for the sake of it.

    Now connect a camera to it and make a little web interface for it to control it with live video

      I know this is an old request, but if you install motion from crisian it is pretty easy to add a webcam (Picam, Pi Noir or USB- works with all of them!) that you can view from a webpage.

      Yes, I will be adding a camera. :)

    Thanks for this one Chris. I have one of those 'plastic card' TV antennas, and a Pan & Tilt with two servos to adjust it. It's been a pet project on the shelf for a few months now, and this will help a lot towards completion. Just need to adjust the code for small movements instead of continuous, and it should work fine. Thanks again!

    You can also shorten your dhcp range from 2-199 in your router and then use fixed addresses from 200 upwards,
    this prevents conflicts. In putty you can give a name to your ip-address and save it, next time you can choose it from the list.

    there is an easier way for the pi to have a "fixed address" rather than using your router a pi address is raspberrypi.local and you can change that in the config

      I touched on this in the video and talk about it in some depth below. In short, you *cannot* guarantee an IP reservation at the client end.

    Not so much into robots (yet) but, that "address reservation" thing as general idea helped me to figure out something about my damn LAN configuration. Thanks!

    Great video! Are there similar programs that can redirect the graphical layout of the controlled computer aswell?

      There are indeed -- and I will come to them in another video fairly soon! :)

    nice video. looking forward to the line following aspect of it. Are you planing on using ultrasonic sensors to detect objects on front or drops in elevation (stairs etc). Thank you for sharing.
