apt-get update doesn't update any software on your device, it just updates the list of available software. if you realy want to get the newest version of everything, you have to run sudo apt-get upgrade (preferably right after the update command).
I see you've got a message about the risk of powering off w/o clean shutdown in the video... But a top tip if you've got a setup w/o keyboard (or even headless) is to look at your router, since unless you've configured the Pi for a static address (which you'd know) then it'll be the router that gives out the IP address to the Pi. Instructions will vary based on router, but they're all pretty similar and you just look at attached devices. If that isn't practical, there are network scanning tools - you'd need to be on the same network obviously but it'd find the Pi for you (they're even available to run on mobile, eg Fing)
+Neil Stoker Hello thanks for the comment. I made this video a while back which I think covers what you are saying. th-cam.com/video/JRfG2-sZqZw/w-d-xo.html
OK, I am a beginner and I enjoyed your video. However, could you please make sure to highlight somewhere the importance for the LED to be the BLUE one? I fried a couple before discovering that LEDs generally need a resistors and the reason why the blue one doesn't is because its voltage is closer to 3.3v (I think 3.2) xD.
+BillsOnBills Exactly the Blue LEDs require more current than the other colours hence you do not need to limit the current, although it's a very bad habbit to not put in resistors. You always want to limit the current to the maximum allowed current. So even if the resistor is small like 30 ohms or so you should put that resistor in series.
Add a shebang to your script Which is #! and set that to pyhton #!/usr/bin/python and set execute rights onto your script file and then you can just start the script without having to first time python.
Hey I am facing a prob wid my project my devices r switching on as soon as I give power supply before giving dem any instructions what can I do for it. Even though I turn of my raspberry pi my devices r running
Yes because just the LED resistor limit the current inside, if you have something like this who will run more time, you will damage the LED or maybe more like output of your Rpi if you use directly from a GPIO
+Guillaume R I agree that you are correct and I would recommend that you do it that way. However in practice I have found it just fine to use 3.3V LEDs directly off GPIO. I have a controller that has been running this way for over a year and have no problems as of yet.
is there a big difference if i have external led lights and external buttons, to be more exact: these buttons: www.conrad.nl/nl/linker-kit-uitbreidingsprintplaat-lk-button2-2-drukknoppen-1267836.html and these lights: www.conrad.nl/nl/raspberry-pi-uitbreidingsprintplaat-lk-led10-red-10-mm-rood-1267848.html?sc.ref=Product%20Details the project i'm working on needs to be fisnhied tommorow night, hope u can see it by then. and if there is a difference do u know how i can connect these to the breadboard ?
+sohaibsaif sohaibsaif Hey, It is possible but the code will be different. Here is the Library. github.com/duxingkei33/orangepi_PC_gpio_pyH3. Here is a link to the read me where they have some examples. github.com/duxingkei33/orangepi_PC_gpio_pyH3/blob/master/README.txt
Hi, I am unable to write the rasbian image to my sdcard on Mac as it says its read only. I have done tons of searching online but couldn't find anything which could help me. Anyone who got the same issue and able to resolve it?
Hey Shane I would like to do a similar thing. But in my project I am using a 8 relay board which I intend to connect it to my house. I want to use the raspberry Pi as a timer to switch on and off the relays. Can you help me in this. I am new to raspberry Pi. I don't know how to program and run it. I brought a Raspberry Pi model A+ so I just have 1 USB port. How do I program it without my PC. If possible can I have your email ID. It will be easier to discuss
Linus Miranda Check other youtube vids to see how to connect a Pi to a Relay board. You can program directly on the Pi using SSH. If you want to use all 8 relay switches, you'll need an extra power supply (5V)
ThatCoder I am trying to connect my Pi A+ to my network but its not connecting. Can you help me to program without using SSH. I want to program just using My Tv , mouse and keyboard. Can it be done?
If you're running an OS that provides you with a graphical interface, you could use a text editor like gedit. If you're using a command line interface, you can use a command line text editor such as nano, pico, vi or vim. You just write your scripts to a file and run from that.
Hi sir, I'm ferdin. When I executed the program using the command sudo python test.py I'm getting an error. Runtime Warning: This channel is alredy is use. Use GPIO.setwarnings(false) to disable warnings
Also sir, I have wrote a simple blink coding and saved it my Pi. That coding works if I type the Command sudo Python filename.py.. if I Power off my raspberry Pi n power on, that program is not running.. How to make that blink program to run by default sir.
unplugging the pi to reset it a bunch of times is bad advice my friend.You could nd up with a corrupted sd card before to long.I know from experince.If you miss it just type sudo reboot,or sudo halt..Are you guys to cheap for a 8dollar usb keyboard?
hey buddy limit yourself to the automation please.Dnt cover the basics of Rpi there are already tons of those over the internet.Just tell us how the connection's go.In the 4th video you told that in the next video you will tell us about the software side of the system but you went to the basic's of GPIO.Please dnt cover that basic stuff.There are many video's about that.Limit yourself to the automation. Thanks
Hey, I am wanting to cover everything from the basics to the more advanced stuff. My next video is going to be about basic GPIO which comes out this week so probably skip that one but the video after that is going to be about MQTT and how to get devices to start talking to each other.
No Problem.But can you help me figure out the problem i am facing till then. I want to know what technology you used at software side ? Also how is your Rpi connected to other nodes which are Arduino's. I would be grateful to you if you can help me THanks
The MQTT video will explain that, but the basic idea is that you run a MQTT broker/server on one of the raspberry pi's and all the others connect to that broker. MQTT allows you to send messages from one device to the next. I use the mosquitto broker which you can find here as well as the python library. mosquitto.org/ and this is the ardunio library. knolleary.net/arduino-client-for-mqtt/ but if you are having trouble understanding how to do it. I am hoping to do the MQTT video really soon. Hope that helps.
When will you upload the MQTT video.I have to make the system in a week.Currently i am planning to use serial communication between Rpi and arduino but i dont think that option would be further scalable.Do you have some kind of documentation.Also MQTT can be used to turn the Arduino pins high and low right ?
Gaurav Harchwani I have just started planning the MQTT video so in a couple of weeks, sorry about that. So MQTT is kinda like serial it just runs over ethernet. I don't have any documentation of my own but the 2 links that I gave in the previous comment is pretty well documented. Also if you google Arduino MQTT tutorial there are a few tutorials. My day job is pretty hectic right now else I would make that video this week so sorry about that. What is your project? what are you trying to do?
This tutorial is awesome. Can't wait for my raspberry pi to come in the mail.
Man, this is the best video tutorial. Thanks and keep going.
great video Shane
apt-get update doesn't update any software on your device, it just updates the list of available software. if you realy want to get the newest version of everything, you have to run sudo apt-get upgrade (preferably right after the update command).
+ARPANettic Productions (discontinued channel) that's why I wrote that you should run upgrade right after update...
Nice video. You may also want to checkout the review of Home Automation on my blog at *paulreviews. com/home-automation-review/* Thanks. Ddt Owen.
go to Google and type in what is my IP address and it tells you it
Nice video! Thank you very much for helping me out 🙂

Ah, I didn't see that, but glad you're aware of it. The video series looks interesting, I'll take a look at some of the others!
Last time I did electronics, LEDs were 1.2 volts and needed a resistor. To drop the current. Are these. 3.3 volt ones special?
u rocked bro
awesome dude!!!!
put some more videos and pleasept some for B+
And what if we have raspbian on sd from the kit?
OK, I am a beginner and I enjoyed your video. However, could you please make sure to highlight somewhere the importance for the LED to be the BLUE one?

Hey I am facing a prob wid my project my devices r switching on as soon as I give power supply before giving dem any instructions what can I do for it. Even though I turn of my raspberry pi my devices r running
whats the sound at the end...?
Hey Shane, why have you chosen raspbian? I saw there are another OSs on the download page.. Thanks!
+Daniel Vilela raspbian is the official OS. It can also run in headless mode and has pretty much everything we need.
OK Sir, thanks a lot..
I'm waiting for that video..
Also if u can upload a video regarding Power pi it will be lot useful sir..
when you test the LED you plug from the 3.3V to the led to the GND without any resistor???
+Guillaume R so that is definitely not the best way to do it but it does work with the LEDs I have. I haven't killed one yet.
Yes because just the LED resistor limit the current inside, if you have something like this who will run more time, you will damage the LED or maybe more like output of your Rpi if you use directly from a GPIO
+Guillaume R I agree that you are correct and I would recommend that you do it that way. However in practice I have found it just fine to use 3.3V LEDs directly off GPIO. I have a controller that has been running this way for over a year and have no problems as of yet.

plz uplod video for window users

the project i'm working on needs to be fisnhied tommorow night, hope u can see it by then.
and if there is a difference do u know how i can connect these to the breadboard ?
Those will work. You are just going to need to find a way to connect them to the breadboard.
This may be a stupid question but how do I turn off the test.py?
+Kyle Wilken Ctrl+C should stop it.
hey where is your next video?
Coming, should be up by the end of the week.

Can we do the same project with an orange Pi?? As it can also run raspbian?? Any one plz tell

You didn't put the commands in the description, bro.
Hi, I am unable to write the rasbian image to my sdcard on Mac as it says its read only. I have done tons of searching online but couldn't find anything which could help me. Anyone who got the same issue and able to resolve it?
+Nishant Sood Your sd card is read only? as far as I know there is a little button on the adapter the you need to slide.
+rom ezry I am using a USB stick card reader which doesn't have a slider
+Nishant Sood is you sd card formatted in NTSF by any chance?
+ShaneYake No its formatted in MS Dos (Fat32 Format). Anyhow I made it from Windows machine. It's working properly.
That's strange... I am glad you got it working.
What if I don't have the black cable?!
The ribbon cable? You can connect the cables directly to the header.
When will the next video be out? :)
I have filmed it already, editing it in the next few days. So this weekend the latest.
Looking forward to it!
ShaneYake do it fast mate.... :) really helpful stuff

commands we use in mac are same in windows ??
Commands for the py script? If that's what you mean then yes, you're writing code in the raspberry now using python
Like. The tutorial but the music at the end was too loud in ear buds and hurts my ears
Hi sir, I'm ferdin. When I executed the program using the command sudo python test.py I'm getting an error. Runtime Warning: This channel is alredy is use. Use GPIO.setwarnings(false) to disable warnings
That happens when the GPIO is already in use. Normally it will just throw that error but everything will work. if it doesn't try rebooting.
Also sir, I have wrote a simple blink coding and saved it my Pi.
That coding works if I type the Command sudo Python filename.py..
if I Power off my raspberry Pi n power on, that program is not running..
How to make that blink program to run by default sir.
+Ferdin Vivian I am working on a video about that soon.
Okay guys
South African?
+Francois van der Merwe Jipe
ek wou se hahaha. Goeie video :D
lol im also south african could you suggest links where to buy the products
aliexpress, banggood, mantech etc.
Thanks Top Dawgz
unplugging the pi to reset it a bunch of times is bad advice my friend.You could nd up with a corrupted sd card before to long.I know from experince.If you miss it just type sudo reboot,or sudo halt..Are you guys to cheap for a 8dollar usb keyboard?
casey james I did not intend for you to rest it constantly, only once or twice but yes a usb keyboard would solve that.
casey james I put a annotation in the video warning about this. Thanks for the comment.
Im' sorry I did not see it.It's better for people to know though
I put an annotation because of your comment :)
ShaneYake Glad to to see you took the initiative.Good for you my friend.
your mac makes me sad
