At Phidgets, our philosophy is that you don't have to be an electrical engineer in order to create sophisticated projects using motors, sensors and other electronics. You simply need to know how to code.


==Introduction==
 
Phidgets are building-block tools for sensing and control from a computer, tablet, or phone. In the programming language of your choice, you create applications that use Phidgets to interact with the physical world. Phidgets connect to a USB port of a computer:

The advantage of using Phidgets is that all Phidgets can be plugged in and used in your project out of the box, without having to follow complex pinout diagrams or configure communication between the device and computer. With Phidgets, we deal with the details of getting the electronics behaving as they should, so you can focus on the programming and details of your final product.

==Data Flow==
Data and control flows up and down the USB connection:
[[Image:wiap-dataflow.jpg|700px|link=|alt=|center]]
You can use [[Using Multiple Phidgets|more than one Phidget at a time]] in your program. You can also use multiple sensors, inputs, and outputs on our I/O boards. Combining these abilities lets you build extensive systems that can sense the environment and react to it.
== Software Channels ==
Every Phidget has one or more channels. There are many channel classes, from the Accelerometer class to the VoltageInput class. Each channel class has its own functions, here is an example of some functions available to the VoltageInput channel class:
[[Image:voltageInput_object.jpg|300px|link=|alt=|center]]
You can check your Phidgets' API for information about available channels. For example, the [{{SERVER}}/products.php?product_id=1018 1018] has five channels (with five distinct channel classes):
[[Image:1018_objects.jpg|600px|link=|alt=|center]]
The Phidget class contains basic functions like {{Code|open()}} and {{Code|close()}} and is used by every Phidget. Other classes will also contain largely the same functions, properties, and events, although there may be minor differences which are explained in the API. For example, the DigitalOutput channel on the [{{SERVER}}/products.php?product_id=1024 1024] has the same functions available as the DigitalOutput channel on the [{{SERVER}}/products.php?product_id=1018 1018] (as shown in the image above):
[[Image:1024_objects.jpg|400px|link=|alt=|center]]
To help you understand the concepts above, we have included a simple C# program that could be used with the [{{SERVER}}/products.php?product_id=1018 1018].
<syntaxhighlight lang=csharp>
using Phidget22;
int main() {
    VoltageInput vin; // define a VoltageInput handle
    vin = new VoltageInput(); //instantiate the class
   
    vin.Channel = 0; //specify which channel
    vin.Open(5000); //open the channel, waiting up to 5 seconds for attach
    System.Console.WriteLine("My channel 0 sensor reads " + vin.Voltage); // Get the voltage value
    vin.Close(); // close the channel
}
</syntaxhighlight>

== Network Server ==
Not only can you control a Phidget locally, but we also provide a tool called the [[Phidget Network Server]]. The Network Server exports your Phidget's channels over your local network:
 
Using the Phidgets API, applications on remote computers, phones, and [[OS_-_Phidget_SBC|Single Board Computers]] can attach to Phidget devices over the network as if they were local.  This includes WWW based applications using the Phidget JavaScript library.
[[Image:NetworkServer_PhidgetServer.jpg|link=|800px|center]]
[[Image:NetworkServer_PhidgetServer.jpg|link=|800px|center]]
This allows other computers on your network to control the Phidget or read data from it. The network server isn't limited to desktop computers- it can also be used with phones or [[OS_-_Phidget_SBC|Single Board Computers]] that are running Phidgets code.
The Network Server also includes the [[Phidget Dictionary]], which is a central place to store your data in key-value pairs.

At Phidgets, our philosophy is that you don't have to be an electrical engineer in order to create sophisticated projects using motors, sensors and other electronics. You simply need to know how to code.


Phidgets are building-blocks for sensing and control using a computer, tablet, or phone. Phidgets enable your software application to interact with the physical world.

The advantage of using Phidgets is that all Phidgets can be plugged in and used in your project out of the box, without having to follow complex pinout diagrams or configure communication between the device and computer. With Phidgets, we deal with the details of getting the electronics behaving as they should, so you can focus on the programming and details of your final product.

Hardware Introduction

Phidgets connect via a USB port:


Some Phidgets are a complete, self-contained sensing package. An example is the 1042 , which measures motion:


Other Phidgets are a 'building block' to use other sensors. An example is the 1048 which allows the use of wire thermocouples:



Finally, a Phidget may be a VINT Hub, made up of versatile ports that can be used as inputs or outputs, and also connect to smart VINT devices.

Programming

For the most part, using Phidgets requires writing software. The Phidgets API is available in many different programming languages:

Core Languages Mobile Languages Other Languages
C Sharp C# Objective C Objective C LabVIEW LabVIEW
C/C++ C/C++ Swift Swift Max/MSP Max/MSP
Python Python Android Android Java
Java Java
Visual Basic .NET Visual Basic .NET
JavaScript JavaScript

The Phidget software libraries are supported on a number of operating systems:

Desktop OSes Mobile/Wireless OSes

OS - LinuxLinux OS - iOSiOS
OS - OS XOS X OS - AndroidAndroid

Network Server

Using the Phidgets API, applications on remote computers, phones, and Single Board Computers can attach to Phidget devices over the network as if they were local. This includes WWW based applications using the Phidget JavaScript library.

Further Reading

With the combination of events, modular sensors, and network support, your system can range from simple to incredibly complex.

We encourage customers to not only build projects for themselves, but also to design and build real-world products using Phidgets. Our libraries can be distributed with your code to your customers.
