 The USB-cable can then be plugged into any USB port, on a laptop, or in a wall-adapter, as long as it can provide at least 500 mA at 5V. Most wall-adapters meet these requirements, so don't worry too much about finding the right one.

+Lastly, find the moisture sensor and a Grove cable. Taking a closer look at the Grove cable you will see that one side is a 3 pin connector (this goes into the moisture sensor), while the other end is a 4 pin connector (this will be cut off in the next step, we won’t be needing that).

+Now you will need to cut the Grove cable to expose the copper wire inside so you can connect it to the Nano Screw Terminal Adapter but be careful not to cut it too short at the side that goes into the moisture sensor (3 pin connector). We recommend cutting the cable close to the 4 pin connector giving you the maximum cable length. If needed you can always shorten the cable afterwards.

 We recommend gathering the cables that will leave through the opening, and zip-tying them to the bottom of the enclosure using the two slits in the bottom-plate, this way it stays organised and is a little bit easier to close.

 ## Usage
 
 Let's take a look at what our Smart Garden can do. To control it, we can either use the dashboard in the Arduino IoT Cloud, or the Arduino Remote app ([Playstore](https://play.google.com/store/apps/details?id=cc.arduino.cloudiot&hl=en&gl=US) / [Appstore](https://apps.apple.com/us/app/arduino-iot-cloud-remote/id1514358431)).

 With a smart garden setup, you can easily monitor the environment of your plant, and water it remotely. In this tutorial, we have gone through the basic elements needed for achieving just that: but there are more things you can do. Below is a list of some fun ideas that you can do with your plant:
 
 - **Automatic watering** - instead of watering your plant remotely, you can also activate the pump automatically whenever moisture drops too low. We do however think it is more fun to control it from a phone, but the choice is yours.
+
 - **Cooling/heating fan** - With some more work, you can connect a cooling/heating fan. This can help you bring the temperature to a perfect level (some plants like it cold, some hot).
+
 - **Humidifier** - a humidifier is an awesome component that increases the humidity (a perfect combo if you also add a humidity sensor).
