ADB should come with the platform tools in Android Studio. Navigate to your local.properties file in the root of your project and you should see a path to the Android SDK on your computer, such as C:\Users\Woodie\AppData\Local\Android\Sdk. Then navigate to platform-tools and an application called adb should be there. To use it, open CLI (like PowerShell or command prompt) and run either adb devices or ./adb devices.
