[otw_is sidebar=otw-sidebar-1]in this projectiot123 tutorial we will Learn the Download Proteus Library of Components.The simulation model of an electronic component contains the information about the input and output relationship of the electronic component in the form of the mathematical equation.

• Let us now summarize all the custom made simulation models required for simulating the embedded system designed based on the Arduino microcontroller development board.
• The simulation software calculates the behavior of the circuit by calculating the mathematical equation of all the components. There are a lot of the software and online tools available for simulating the circuit or embedded systems, among them Proteus holds the significant position which is equally popular among students and professionals.
• While simulating any circuit it is important to keep in mind that the simulation models of all the components that are being used in your circuit or embedded system must be present in the library of the software.
• If you have the component in your circuit whose simulation model is not present in the library of your software then the software will be unable to simulate the behavior of the circuit.
• In short you must have the simulation models of the components in order to imitate their actual behavior.

#### Ultrasonic Sensor Proteus Library

• Ultrasonic sensor works on the principle of the echo affect, it has ultrasonic wave transmitter and receiver mounted side by side on the module.
• It is generally employed in order to detect the presence of any obstacle in its vicinity, the distance between the sensor and the obstacle is determined by calculating the time it takes by the ultrasonic waves to strike the obstacle and measured by the receiver.
• The ultrasonic sensor in the Proteus looks like the following:

#### Flex Sensor Proteus Library

• The flex sensor is a resistive sensor whose resistivity alters corresponding to the angle to which it is bent.
• The flex sensor is generally employed in the voltage divider configuration with simple resistor connected in series with the flex sensor.
• The voltage is read at the flex sensor with reference to ground, when the flex sensor is bent its resistance is altered due to which the voltage at the resistor also varies.
• The voltage reading is then fed to the microcontroller which processes the signals for further action.
• The flex sensor is usually employed in the human actuated robotic arm(Download Proteus Library of Components).
• The flex sensor in the Proteus looks like in the following image.

#### Flame Sensor Proteus Library

The flame sensor also known as the flame detector is a type of sensor that senses the presence of the fire in its vicinity. The fire sensor detects the presence of the fire by detecting the IR (Infrared Radiation) waves present in the fire. The fire sensor also consists of the operational amplifier which conditions the measured signal so that microcontroller can easily read the signals and successfully process the signals. The flame sensor in Proteus looks like in the following image.

#### PIR Sensor Proteus Library

PIR (Passive Infrared) sensor is also commonly known as the motion sensor which measures the Infrared (IR) light radiating from the object in its field of view. So when the object comes in its field of view the readings of the sensor gets disturbed and thus detect the presence the object in front of it. The PIR sensor in the Proteus looks like in the following image:You can download the simulation model of the PIR sensor from the following link.[otw_is sidebar=otw-sidebar-3]

#### Light Dependent Resistor Sensor

The LDR sensor is the abbreviation of the Light Dependent Resistor and as the name implies the resistance of this sensor varies in relation to the intensity of light, greater the intensity of light lower will be resistance of the LDR sensor. Just like the flex sensor the light dependent resistor is also used in the voltage divider configuration, the resistance of the LDR sensor alters as the intensity of light projected on the sensor varies. The LDR sensor in the Proteus looks like in the following image.

The simulation model of the LDR is installed in the Proteus by default you do not need to download any other file in order to use this sensor.

#### Gas Sensor Proteus Library

Gas sensor is installed in order to detect the presence of gas in its vicinity. The voltage at the output of the Gas sensor varies in response to the presence or absence of the smoke thus in this way that is way by variation of the voltage one can sense the presence of the smoke. The Gas sensor in the Proteus looks like in the following.You can download the simulation model of the Gas sensor from the link in the following.You can  Download Proteus Library of Components for Simulation and Pcb Design

#### L298 Motor Driver Library for Proteus

This L298 Motor Driver is used for controlling speed and direction of DC Motors. We can use it to control DC Motors as well as the stepper Motors. Its quite widely used in Engineering Circuit and different Engineering Projects

Proteus doesn’t contain L298 Motor Driver Library in it so, our team Projectiot has designed it in Proteus and its now ready to simulate in it.I have also posted a project Line Following Robot Using Arduino in which I have shown how to use this L298 MOTOR DRIVER in Proteus ISIS. I will also post a tutorial soon in which I will interface this L298 MOTOR DRIVER with PIC Microcontroller and AVR,8051 Microcontrolelr but you have to wait a little.  I hope you  are gonna enjoy it.

You can downlaod this  Motor Driver Library for Proteus by clicking the below link :

#### DS1307 Library for Proteus

DS1307 module is an RTC(Real Time Clock) module which is used in projects where real time is required. This RTC module is basically a clock and you have to program it for once and then it keeps on ticking forever. These are used mostly in different Engineering projects and is quite helpful. Proteus already have this module in its Library but its not much attractive and looks like a simple module. So, our team  given it a stylish look and its just a click away from you.OUR team designed its rtc library in Proteus which you can download by clicking the below link

##### GSM Module Proteus Library

GSM (Global System for Mobile Communication) is the protocol that defines the way of sending and receiving messages wirelessly so there should be some hardware that supports this type of communication. The device that is based on GSM is called the GSM model or GSM module. The GSM modem come integrated on mobile phones that enable the phones to communicate wirelessly under this GSM network. In the similar way the GSM modems comes also with USB interface to let them connected to the computers or laptops thus enabling the GSM wireless networks on the computers or laptops. The GSM modem has the slot on which the SIM card resides. A GSM modem can supports GSM networks of multiple frequencies. Besides these GSM modems the hardware for GSM communications to be used in the embedded systems projects is also in market and is usually called GSM module. The simulation model of the GSM module in Proteus looks like in the following image:

#### C945 Transistor Library for Proteus

C945 is a transistor used in many electronics circuits. It’s main purpose is to use as   Amplification  or in cases it is also used for generating different signals. C945 is not available in Proteus Components library list. Our team Projectiot  has designed this NPN  transistor and you can download it by clicking the below LINK:

#### Magnetic Reed Switch Library for Proteus
