Hello everyone, i'm new to Arduino and I need some help

[size=2]Hello everyone! [/size]
[size=2] Like i said i’m new to Arduino, and i have an idea for a science project but i’m not sure if its possible. What i want to know is that would i be able to hook up a heat sensor and a water sensor? or a dampness sensor so the arduino would be able to release water and turn on a lamp on it’s own? And i read up and know you need to program it with codes but what would i have to do to make it sense when an area is too dry or too cold then automatically balance it by turning on a light bulb or releasing water from a source?[/size]
[size=2] I know i would have to connect a wire and a blocker type thing to a hose which when alerted with a signal would open and release the water then close when it needed, and for the lamp i would connect another blocker type thing which would let the electrical charge through when needed turning on the bulb but what would i need to do with the codes to make it sense those things?[/size]
[size=2] I’m so sorry for how very poorly worded this is but thank you so much for the help![/size]

Hi,

Since you are new to Arduino, we suggest you to start experimenting with an Arduino microcontroller to learn how to code it.
The most popular Arduino board, is the Arduino UNO.
This Arduino Starter Kit is an excellent kit to walk you through the basics of Arduino and help you learn creating several projects.
You can also find a lot of sample codes and exemple projects in this page.

This being said, you can probably use a temperature sensor as this Waterproof Digital Sensor and a Water Flow Sensor as this Adafruit Water Flow Sensor.
Here is an example of Water Flow Sensor Arduino Interfacing.
You might want to use a Water Pump to flow water from a water source, like this 5V Micro Liquid Gear Pump.
To turn on a lamp from an AC Source, you will need a relay module attached to your Arduino board like this Arduino Compatible Relay Module.
Here is an example for AC lamp control with Arduino.

Regards,
