All raspberry devices MAC addresses started with B8:27:EB (for RPi4 B they start with dc:a6:32, replace where appropriate).
So, on *nix systems, this can be accomplished by executing the following command:
nmap -sP 192.168.1.0/24 | awk '/^Nmap/{ip=$NF}/B8:27:EB/{print ip}'
where 192.168.1.* will be your local network mask. You will get an answer like:
Nmap ...

If you're running MacOS or Linux, try this one:
$ arp -na | grep -i b8:27:eb
On windows, you can use:
arp -a | findstr b8-27-eb
On RPi 4B, you need to use different string for comparision (dc:a6:32:be:95). You can check it on your RPi by
ip -br link
There will be entries for each network card. eth0 is cable internet, wlan0 is the WiFi.

If you want to login as root using SSH or WinSCP you need to edit the config of SSHD, do this:
Login, and edit this file: sudo nano /etc/ssh/sshd_config
Find this line: PermitRootLogin without-password
Edit: PermitRootLogin yes
Close and save file
reboot or restart sshd service using: /etc/init.d/ssh restart
Set a root password if there isn't one already: ...

later I found out another solution to make it work for Remmina 0.9.99.1. You can change the security authentication for the VNC server to be VNC Password instead of Unix password and create an admin user credentials so you can use it in the remote connection as the following:
On VNC Server side on Raspberry Pi 3
Go to the options on the VNC Server on ...

To make the answer a little more explicit, here are all the steps I took to get it working:
On the raspberry pi
Install tightvnc server (designed to support lower bandwidth)
sudo apt-get install tightvncserver
Configure vnc desktop with screen resolution and color depth
vncserver :1 -geometry 800x600 -depth 24
On the mac
Enable the native vnc client ...

I can switch my TV on using the following command:

I've just encountered the issue too.
As an alternative to aibrahim's method if you are doing it remotely via ssh, here's my steps to VNC to display :0.
Setup password using sudo vncpasswd -service
Add the following lines to /root/.vnc/config.d/vncserver-x11 as described in RealVNC: Support legacy viewers

Ok I solved this problem by adjusting the display options in Raspi-config. Using the following:
sudo raspi-config
Advanced Options > Resolution > DMT Mode 85 1280x720

omxplayer now has an option to set the background to black.
omxplayer -b
It works both on the terminal and in X.
This feature should be in the current version available in raspbian.

By default the raspberry's name is raspberrypi. You can just 'ping raspberrypi' and the ICMP echo reply gives you the IP address. It worked for me. Make sure though the DHCP server is reachable as the raspberry's NIC is by default in DHCP client mode. Otherwise the raspberry gets an APIPA address.

If you want to use a GUI application for it, you can use Yakala tool (https://github.com/mozcelikors/yakala) for Debian/Ubuntu. This tool helps you not only search for available Type B and Type C networks, but also helps you to directly SSH into the network:
sudo add-apt-repository ppa:mozcelikors/yakala
sudo apt-get update
sudo apt-get install yakala
or

simulate this circuit – Schematic created using CircuitLab
Assume you have a Raspberry Pi connected to your Router at home.
Normally your router will give IP addresses to all devices attached to it.
In my example the Router assigns to the Raspberry Pi the IP of 192.168.0.101
This IP is only visible in your internal Network and not from the World ...

I use the free Fing app in my android smartphone. It scans the network and shows the connected devices by type, including Raspberry Pi, as well as scanning available ports. Handy to see if SSH, web or VNC are enabled and running.

For your system-level watchdog, I was going to suggest building a hardware watchdog. There are connections on the RPi board (the P6 header) which you can short to reset the device. You could connect this to a countdown timer chip, and have your app regularly use the GPIO pins to reset the timer. If your app stopped working for too long, the countdown would ...

You cannot login as root because Raspbian does not have a root password. See Raspbian root default password
Normally ssh does not allow root access because this is considered a security risk. You should be able to do everything you need using sudo (which is the normal Debian practice).
If you REALLY want ssh root access it can be enabled.

The simplest solution is to install RealVNC Viewer. You can download it from here, and it is available for Linux, MacOS and Windows. The issue is with the encryption schemes used by different VNC servers.

You can use VNC. It's is a graphical desktop sharing system to remotely control another computer.
If you have Raspbian Jessie or later, VNC Connect is pre-installed. To enable VNC:
Go to your Raspberry Pi > Open the application menu > Preferences > Raspberry Pi Configuration > tab Interfaces > Enable VNC
If not, install VNC server manually :
sudo apt-...

0x5344 from the oemid means SD as in SanDisk. Type is probably not easy; I guess it is their internal name.

I would like to know if the reset pin is an okay method of starting the Pi assuming it was properly halted.
There isn't actually a pin, but there are two holes at P6 on the rev. 2 board (~1cm left of the HDMI jack) that if shorted together will reset the power. You can attach a switch to this.

You may want to use the usbnet driver (usbnet homepage) which allow you to map USB port as they were Ethernet port. Then you can route traffic through your USB port and therefore ssh your RPi by the mean of a regular USB cable.

In linux and MAC, you can also type in "arp - a" in the terminal and you can get a list of connected devices, look for the one with B8 in it, example: 192.168.4.5 @ B8... will be the raspberry pi IP.

TeamViewer cannot be used on the Raspberry Pi at this time. They do not have a build for it.
You can install a VNC server, and that would be your simplest option. You would have no issues connecting on your LAN, however if you wanted to connect remotely, you would need to set up port forwarding.
An alternative to port forwarding would be to use a NeoRouter ...

You can install and run piControl, a Node.js web application to shut down or reboot your Raspberry Pi.
More info here.
To make your Raspberry Pi reachable from the Internet, you should give it a static IP address on your local network, and forward the public HTTP default port (80) to the local IP address of the Raspberry Pi.

In terms of remote control, you've got a few options.
You could SSH into the Pi and control it via the command line. You could install VNC on the Pi and then use a client on another computer to connect to it that way.
Alternatively, you could use a bluetooth dongle and pair up a Wii remote, PS3 controller or anything else that uses the bluetooth protocol. ...

That file is not on rpi 3 you are trying to connect to, but on the computer where you are trying to connect from (Ubuntu?). Just run
ssh-keygen -f "/root/.ssh/known_hosts" -R 192.168.1.234
on your computer. Not on the rpi.

Another option with Raspbian is feh.
connect from your pc with ssh -X user@ip.of.your.pi (capital X!)
user@raspi:~ $ feh /path/picture.jpg
Note: loading is not superfast, wait patiently.
If the package feh is missing, you can install it via cli:
sudo apt-get update; sudo apt-get install feh

Disclaimer: I have no experience with any ssh software under windows.

You really should check back with your school's IT department, whether they like your idea. If you just do it right away, and they find out, you are in serious trouble.
I know, school networks are oftentimes very amateurly monitored, so your chances may be quite ...

The RPi and the PC need to be in the same logical network, which they are not.
The computer is in the 192.168.225.0/24 network, and the Pi is in the 192.168.137.0/24 network.
You need to change the IP address of the Pi to be in 192.168.225.0/24 (example: 192.168.225.10 with subnet mask 255.255.255.0).

Only the Raspberry Pi Zero , Zero W , Model A and Compute Module can act as USB device. Other models can not act as USB device. This is a hardware limitation which cannot be worked around in software.
You will not be able to make the Pi act as PS/2 keyboard or mouse. Not with the GPIO pins, that is.
Here is a guide for turning the Pi Zero into an USB ...
