Re: Pi Zero W won't boot

Welcome to the Raspberry Pi forums. It is unlikely that you have a similar problem, since both previous posters have resolved the problems they reported. There is a Troubleshooting guide in Issue 60 of the MagPi magazine which you can access for free online. https://www.raspberrypi.org/magpi/issues/...

If you have exactly copied what it says in the anonymous book by "Prof Ibrahim" then I think that the author has got the installation instructions wrong.

Re: How to control on board led over internet

No, you don't have to buy a domain name.

If you want to use 'web' http protocols to access your project you will need to run a web server. It does not have to provide a visual web site.

The gpiozero Python library module contains a simple example of how to call a function in response to a button press. Maybe the function to be called could be the second script?

Re: arp-scan not detecting devices

Another guess. (Only that, since TalkTalk have never supplied me with a router.) Maybe the default configuration of your new router is that it isolates WiFi client end-stations from each other, and allows them to communicate only with 'internet' hosts external to your lan, not with each other? Can a...

The alternative to all this is decrease the renewal time on your dhcp leases in your routers settings. Instead of around 24 hours, use 5 minutes.

Further to what @SurferTim said: The router or gateway is simply another, although distinctive, node on your local area network. Your RPi does not have a persistent connection to it. So it has no built-in automated way of knowing that its designated router has gone away or been changed. Maybe you ne...

That seems self-explanatory.

The opinion of the Python interpreter is always correct, even when you think it is wrong.

Re: where do change the partition size on the sd card or your computer?

You need to modify the microSD card containing the NOOBS Installer before booting the RPi with it.

It will probably be necessary to mount the NOOBS Installer card in some other computer to carry out that modification.

Re: problem in the While loop

Welcome to the Raspberry Pi forums.

If the script works perfectly why do you need to modify it?

The nature of a while True: loop is that it never exits, since the Boolean constant True is always True. What behaviour were you expecting?
