It will then attempt to log in with the account name "pi". We are instructing the SSH application to access the device at the given IP address. Enter the IP address for your Raspberry Pi after the symbol. We are opening the ssh application to login to the Pi account. Type ssh followed by a space and the word pi. This clears away the information in our terminal. We need to find the address assigned to your Raspberry Pi. The IP address provided to the router is unique. A typical router address looks like this, 192.169.001.122. An IP address is a set of numbers divided into four sections of three numbers each. The Raspberry Pi will be assigned an IP address. This is true for both the wireless and ethernet connections. The Pi is connected to our router and has received an IP address from the router. To access the Pi we will use the SSH connection. Please replace my IP address with the one for your Pi. Open the Terminal on Mac or Windows and type this command, ping -c 3 raspberrypi.ĭuring these lessons, I will use the IP address for my Pi. Mac Terminal IP address lookupĪs long as your computer is part of the same network we can look up the IP address of the Raspberry Pi. All three use their version of the command line. I reviewed the process for getting the IP dress using Mac, Windows, and Chromebook. This is needed to log into the Pi with Secure Shell, SSH. We need to know the IP address for the Raspberry Pi. Unplug the power supply to the Raspberry Pi before checking the microSD card. Check the card to make sure it is properly inserted. If the green LED doesn't blink and nothing appears on the display this may be because the microSD card isn't properly inserted. It looks for the WPA file to set up the wireless connection. It looks for the SSH file to setup SSH services. What do we see on the connected display? The Raspberry Pi displays lines and lines of text as it boots. This means the Pi is waiting for instructions from us. The green light will blink for a few minutes while the Pi boots. This activity is usually from the Pi reading and writing information to the micro SD card. A blinking green LED shows there is activity on the Pi. A red LED indicates the Raspberry Pi is on. At the very least, you will need to connect a keyboard and mouse to the Pi and fix some issues.Ī couple of lights on the Pi will turn on. Unplugging will turn off the power and crash the computer. Raspberry Pi 3 and 4 with wireless capabilities don't need an ethernet cable.ĭon’t unplug the Raspberry Pi until everything is setup. Below is an image of a wireless router and the Ethernet ports on the router. The Ethernet cable usually connects to a drop. If you are using Raspberry pi (version 1.xx or 2.xx) without wireless capabilities you need to connect it with an Ethernet cable to a router. The Pi will be controlled by your Mac, Windows, or Chromebook. This is very useful because we can use any computer. We are going to log into the Raspberry Pi from another computer. This means we are not going to physically connect to the device when working with it. We are going to run the Raspberry Pi in what is called the headless mode. Connect an external display to the Raspberry Pi with an HDMI cable. It is useful for first-time users to get some visual feedback. This gives us a sense of what is going on. For these lessons, we are going to connect a display. The weather station does not need a display, keyboard, or mouse. The USB ports are used to connect a keyboard and mouse. The Raspberry Pi has connections for a display.
