Sound Sensor Library for Proteus

Update: We have created a new version of this library, which you can check here: Sound Detector Library for Proteus V2.0.

---

Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new Sound Sensor Library for Proteus. We are presenting this library for the first time and I would give the credit to our team, without their support it won't be possible. Proteus doesn't have this module in its library and it is used in a lot of Engineering Projects these days. This sound sensor is used to detect the sound in the surroundings and is normally known as the Sound Detector sensor. It won't recognize the sound. As we can't produce the sound in Proteus, that's why we have placed a TestPin. When this TestPin is HIGH, that means we have sound in the surroundings and if it's LOW then there's silence. Analog sound detector sensors are also available but our sensor is a digital one. So, now let's have a look at How to download & simulate this Sound Sensor Library for Proteus:

Sound Sensor Library for Proteus

• First of all, download the Library files for the sound detector sensor by clicking the below button:

Sound Sensor Library for Proteus

• Open this downloaded zip file, and extract below three library files:
  • SoundSensorLibraryTEP.LIB
  • SoundSensorLibraryTEP.DLL
  • SoundSensorLibraryTEP.HEX
• Place these three files in the Library folder of your Proteus software.

Note:

• If you are having problems in adding a library in Proteus 7 or 8 Professional, then you should read How to add new Library in Proteus 8 Professional.

• Now restart your Proteus ISIS software and in the components section, make a search for sound sensor, as shown in the below figure:

• As you can see in the above figure, we now have 3 sound sensors in the Proteus database.
• So, now I am gonna place all of them in my Proteus workspace and here's how they look like:

• They are all similar in operation, I just changed the base color as there are different versions available.
• Now in order to make them work, we have to add the hex file.

• Double click the sensor to open its Properties panel and in the Program File section browse to SoundSensorLibraryTEP.HEX file.
• We have placed this hex file in the Library folder, here's the screenshot:

• Now click OK and our sound detector sensor is ready for simulation.
• So, let's design a simple circuit to test it out, as shown in the below figure:

• When the TestPin will get HIGH, that means we have sound in the surroundings. In that case OUT Pin will also go HIGH.
• In case of silence, OUT Pin will remain LOW.

• Let's run our simulation and test it out as shown in the below figure:

• So you can see in the above figure that LED is ON when the TestPin is HIGH and its OFF when the TestPin is LOW.
• So that's how you can detect sound in Proteus.
• I have also created this video which will give you a better understanding of How to download and use this Sound Sensor Proteus Library.

I hope you will like this Proteus Library. If you have any suggestions regarding this Proteus Library then ask in the comments and we will try our best to resolve them. Thanks for reading. :)

Introduction to Arduino Duemilanove

Hey Fellas! Hope you are doing well. I feel pleasure to have you on this platform. Today, I'll discuss the detailed Introduction to Arduino Duemilanove which is a Microcontroller Board, introduced by Arduino.cc and is based on ATmega168 or ATmega328. It comes with 14 pins that can be used both ways: Input or Output. Duemilanove means "2009" in Italian. Arduino boards have always been a good pick for hobbyists and students who intend to design projects that are mainly related to embedded system and automation. These boards are similar to microcontrollers, with little advantage over them as they come with some built-in peripheral features, setting you free from buying external components to employ automation in your project. If we focus on Arduino Duemilanove, it incorporates an ICSP header, a power jack, a reset button, and USB connection. A 16 MHz crystal is added on the device, aiming to produce clock pulses with regular intervals. In this post, I'll try to cover each and everything related this Arduino Board i.e. main features, pinout, pin description, software used and applications. Let's jump right in.

Introduction to Arduino Duemilanove

Arduino Duemilanove is a Microcontroller Board that is based on ATmega168 or ATmega328.

• It comes with 14 I/O pins, out of which 6 are used as a PWM output Pins.

This board is useful where low speed and memory space is required. You can not compare it with Arduino Mega that proves to an ideal choice for high-speed applications. Still, if you aim to produce a project with simple functions, Arduino Duemilanove comes handy and stands fit for your technical requirements. It is a most recent version of the board housing USB connection and can operate at 5V with an Input voltage ranging between 6 to 20 V, however, it is advised to keep the voltage range from 7 to 12 V.

• The Flash Memory is different depending on the microcontroller incorporated into the board: 16 KB for ATmega168 and 32 KB for ATmega 328. Out of this total flash memory, 2 KB is reserved for a bootloader. 

Similarly, SRAM featured on the device is 1 KB  while using ATmega168 and 2 KB for ATmega328. 

• This board can be powered up both ways: connecting with a computer using USB cable or using DC adopter.

A reset button is added on the device that helps in resetting the module in case there comes a glitch in a running program and module requires instant reset that brings it back to the initial condition.

• There is a built-in LED connected to digital pin 13, toggling between ON and OFF as you send HIGH and LOW respectively.

2. Arduino Duemilanove Pinout

Following figure shows the pinout of this Arduino Board.

• There are total 28 physical pins on the board and six pins are available on the ICSP header. Four female headers are available covering all physical pins for the connection with the external devices.

3. Arduino Duemilanove Pin Configuration

In the previous section, you have got a brief overview of the Arduino module pinout. Now, we will highlight the major functions associated with each pin, so you can anticipate what each pin is capable to perform, helping you use the relevant pin for your project.

Digital I/O Pins

There are 14 digital I/O pins on the board that can be used as an input or output based on requirement. If you are working with sensors, these pins can be made as an input to accept the digital input from the sensor, similarly, if you are aiming to control the motor, these pins are used as an output for writing the required command to control the motors.

Analog Pins

There are 6 analog pins available on the board. These pins can accept any value, unlike digital signals that are designed to deal with only two values: HIGH and LOW. The following figure shows the location of analog pins on the board.

PWM Pins

There are six PWM pins (out of 14 digital I/O pins) incorporated on the board. PWM (pulse width modulation) is a process for getting analog results with digital means. These pins appear on the right side of the board as you place the board with power jack pointing upward.  Following figure shows the placement of these pins on the board.

ICSP Header

ICSP (In-Circuit Serial Programming) header is added that help to connect the board with computer and upload a sketch in case USB port is not available.  This feature is mainly used to program Arduino with another Arduino.

Power Source Pins

There are four main voltage sources i.e. Vin, 5V, 3.3V, AREF, available on the board. The Vin is the input voltage that ranges between +7 to +12 V and comes from the external power source. The board operates at 5V while 3.3V is the operating voltage of each pin. There are four ground pins on the board where one is reserved for AREF and another for ICSP header while remaining two are available for the board. The AREF is an Analogue reference voltage, used for analog pins. The following figure shows the power source pins.

Communication Protocols

Common communication protocols like SPI, UART and I2C are available on the board. It is important to note that SPI communication is available on both: digital I/O pins and ICSP header pins.

Serial Peripheral Interface (SPI) is commonly used to send data between microcontrollers and small peripherals such as sensors, shift registers, and SD cards. It comes with separate clock and data lines, layered with a select line to choose the device for communication.

Similarly, I2C is a two-wire interface that contains two main lines known as SDA and SCL where former is s serial data line that carries the data and later is serial clock line that is used to synchronize all data transfers over the I2C bus.

4. Programming and Communication

Almost all modules falling under the Arduino family are programmed using  Arduino IDE - Official software introduced by Arduino.cc for programming Arduino Modules. This software is compatible with common operating systems like Windows, Linux or MAC.

• You need to take care before installing the software version for your system i.e. if you want to download Arduino IDE App version, you must have Windows 10 installed in your system as app version is not compatible with Windows 7 or 8.1.

The software is very easy to use and is readily available on the Arduino Website. It is an open source software i.e. you can use it freely and modify your Arduino Board as per your requirements. Some basic codes are already available on the software, you just need to connect the board with the computer and upload the required program and start playing with your board right away.

• Arduino never fails to keep your budget at the bare minimum as no external burner is required to burn the code inside the module due to Module's built-in bootloader, however, if you aim to insert a new controller on the module, you have to install the bootloader again using IDE software.

Arduino IDE comes with a number of options to select the required Arduino Board, simply go to Tools Menu and click Board section and select the board you are working on.

• Software comes with a compilation option that allows you to see the code compilation on the bottom of the screen as you upload the code, generating a code hex file which then is transferred to the board.

The physical pin 0 and 1 are used for UART communication and FTDI  chip on the board sets a pathway to bridge the serial communication between FTDI drivers and USB. As you send the data using FTDI chip and USB connection, the RX and TX will flash, indicating information is being transferred to the computer.
