1. Installing An OS!

NOTE: Any references to the network "StemRoom" should be replaced with "StemSpot"

Raspberry Pi Imager - You'll use this to install the OS on the PiCar, and change some settings to get it connecting.
1. Install this for the operating system you're using (Probably Windows).
2. Once installed, you'll be met with this. Close out for now.
3. The OS Installation will be completed later, so hold off on configuration for now.
Putty - This is used as a remote terminal for the Pi. Because the PiCar will be roaming without a display, this allows easier access and copy/paste.

1. Installation should be pretty simple. Just click through the prompts, and use the default settings.
2. After it gets installed, you can close out of the notepad opened.
Travel Router - This is used to create the network "StemSpot." While you are configuring, setting up, communicating, and driving the cars, both the client, and car need to be connected to the router. More information here: (You'll need to be logged in to access)

Are you ready? Let's put some of those prereqs to work!

Open Raspberry Pi Imager
Insert a Micro SD Card into the computer with Raspberry Pi Imager, to install Raspberry Pi OS on the SD.
1. The Raspberry Pi Device is "Raspberry Pi 3"
2. The Operating System is "Raspberry Pi OS (Legacy 64-bit) Lite"
3. Make sure the storage device is the SD card for the PiCar.
Press "Next", and then Select "Edit Settings"

Copy these settings exactly:

Set Hostname: PiCar<Num> (Replace the hostname "PiCarNum" with PiCar followed by the ID (1,2,3, or 4) Ex: "PiCar2")
Set Username and Password:
1. Username: pi
2. Password: STEMROOM6041
Configure Wireless LAN: For WiFi passwords, click here You'll need to be logged into an account with access for it to function.
Set Locale Settings:
1. Time Zone: America/New_York
2. Keyboard Layout: us
Services:
1. Enable SSH: On
2. Use Password Authentication: True
Options: No Change

You can leave the options tab default.

You can now remove the SD Card from the computer, and insert it to the Pi.
Insert Batteries, connect Pi Power, and wait for it to start up. Wait 5 Minutes until the next step.
No... I mean it. Set a 5 minute timer, and wait. This is a first startup for the Pi, and you'll have to give it some time to setup the filesystem, and connect to the network.
Make sure the computer you're using is connected to the "StemSpot" network, or all the following steps will not work.
Open Putty
1. Under "Host Name (or IP address)" Enter the hostname you set before. Ex: PiCar2
2. Select Open, and wait for it to connect
  1. On the off chance it does not connect, you can try setting the IP address of the car using an app like Fing to scan for the device.
3. Enter the username: pi
4. Enter the password: STEMROOM6041 Key presses for passwords don't show. After typing, press enter.
You should now see a screen like this:
Update the Pi - To update the pi, there are two separate, but similar commands you will need to enter. Remember to only type one in at a time, and let it run. You can right-click on the center of the PuTTY window to paste

sudo apt update -y

sudo apt upgrade -y

Now, just reboot the Pi, and the OS will be updated.

sudo reboot now

Now, we'll setup some custom settings and software to get everything running smoothly.

Reconnect to the pi using PuTTY, and use the same credentials

Open your home directory
```
cd ~
```
Make the script using nano
```
nano wifirecover.sh
```
Paste in the following code by copying the text in the computer, and right clicking on anywhere in the putty window.
```
ping -c4 google.com > /dev/null

if [ $? != 0 ]
then
  echo "No network connection, restarting wlan0"
  /usr/sbin/ifconfig wlan0 down
  sleep 5
  /usr/sbin/ifconfig wlan0 up
fi
```
1. Use the keyboard combination Ctrl+X, Then press Y, Then press Enter, to exit
Now, we'll install cron. This lets you schedule tasks for certian times. In this case, it will check for internet connection intermittently.
```
sudo apt install cron
```
Crontab uses a text file for configuration, so we'll open it now.
```
sudo crontab -e
```
Select Nano as the text editor
Add this exact line to the end of the text file by copying in the computer, and right clicking on anywhere in the putty window.
```
1 * * * * /bin/sh /home/pi/wifirecover.sh >/dev/null 2>&1
```
Use the keyboard combination Ctrl+X, Then press Y, Then press Enter, to exit

YIPPPEEEE!!!! Your Operating system is now installed, and ready to install the PiCar Code!!!
