00:00 - 00:30 [Music] [Music] hello viewers
00:30 - 01:00 welcome again to the moo course on Internet of Things Design Concepts and use cases in this video we will learn about ardino ardino is an open-source electronic platform which is based on very lowcost hardware and software basically it is based on microcontroller it can take input from sensors or you can say it can read the sensors or actuators it can read the data
01:00 - 01:30 and it can process the data and finally the output is able to control the outside world or the physical world maybe it can uh you know that control the motors or it can control the switching on the LEDs or it can sometimes control even the publishing of online content also so as I have told that it is based on microcontroller now let us see that what is microc controller microcontroller is basically
01:30 - 02:00 a very small computer which has the its memory or Ram or some other peripheral devices connected with it so basically it has the digital uh electronic devices which is built into it right and it is also known as the embedded computer system which repeats the programming for example at Mega 328 that microcontroller we use in ardino Uno now
02:00 - 02:30 uh let us see that what is ardino and some we will get some introduction to ardino as I have told that ardino is an open source based right it is a prototype platform or electronic platform which is open source based on an easy to use hardware and software very lowcost cheap easy to use hardware and software it consists of a circuit board right which can be programmed and which is referred to as your microcontroller that board microcontroller is a basic of that and a
02:30 - 03:00 redimed software which we call as a ardino ID that is your integrated development environment right with which we can write some code and upload in the computer code to the physical board the project of ardino uh was started in 2005 for students in ia uh Italy and it aim to provide an you know easy and lowcost method for hobbyist and profession profal to interact with the environment
03:00 - 03:30 using the actuators and the sensor there are many types of ardino board for example ardoo ardino Mega ardino micro ardino Nano ardino zero and many more right but one thing is common to each and every board that they can be programmed using the ardino ID every ardino board has its ardino ID and with this you can interface with the physical world the reasons for different types of Bo are uh the uh requirement of the
03:30 - 04:00 different uh you know power supply or the connectivity options as well as different types of applications we will see one by one that how uh different ardino boards are used for the different applications ardino boards are available in different sizes right form factors and different number of IOP pins some ardino board has 20 digital input output pins some ardino has you know 14 digital input output pins and so on
04:00 - 04:30 some of the commonly known and frequently used ardino boards are as I have told ardino Uno ardino Mega ardino Nano ardino micro ardino lilipad Etc and there are some addon modules also that called the ardino shields which can be used to extend the functionalities of ardino boards now these are the various different uh you know ardino boards that is first of all is your ardino Uno youo
04:30 - 05:00 is the most popular and widely used development board right besides this ardino mini is there micro lilipad Nano Mega 2560 0 and many more now these are some uh photographs of the ardino boards as you are seeing that in the middle we have shown this ardino Uno board besides that there are many things for example ardino Lily Pad is there and Bard you know uh is there another you must be seeing seeing here DIY ardino this
05:00 - 05:30 ardino actually with this help you can uh you know develop your own ardino board right so these are the various types of ardino now we will go in detail of each and every board first of all as I have told that ardino is the most popular choice among the commonly used because it is very cheap and it is easy to learn and use right and also a variety of pre-existing or the pre-made modules are available so that it makes
05:30 - 06:00 uh you easy for developing the new applications or the new project it consists of uh 14 digital input output out of which six we are using as 8bit uh pwm means pulse withd modulation pins we will see what do you mean by this six pins are the 10 bits analog inputs right and the other communication Port are there for example SPI that is serial parallel interface i2c that is your inter integrated circuit and U that is
06:00 - 06:30 your universal asynchronous receiver transmitter it is powered by an at Mega 328 various applications are there that is your ardino is used in do it yourself projects in developing projects based on code based control development of uh you know automation system as well as designing of the basic circuit design next is your ardino Nano ardino Nano is basically the small version of Uno right
06:30 - 07:00 the only difference is that it is breadboard friendly as you are seeing that there are some pins here and that you can directly put up into the breadboard right and also it has the lack of DC power jack and the uh it has mini USB port in replace of the usbb port which is available in ardino Uno and it is very small size and cheap applications are embedded systems then automation then robotics control systems and instrumentation next is your ardino
07:00 - 07:30 Leonardo ardino Leonardo has the uh controller that is known as your at Mega 324 that as the chip rather than is your at Mega 328 and it has I have told you can some ardino has the more number of pins so it has 20 pins uh digital input output pins analog 12 pins and also the pwm that is your seven pins whereas in 328 we have the 14 IO pins and analog input was
07:30 - 08:00 at Mega 32 u4 has a built-in USB communication so this allows the board to connect with uh you know to a computer as a human uh interface device or a virtual com device application are there that is your Industrial Automation health and security systems creating wireless keyboard automatic pill dispenser then water level meter next is your ardino micro ardino micro is a type of Leonardo only but it is a small form factor and
08:00 - 08:30 breadboard friendly sized board right its functionalities are same as your ardino Leonardo only difference is that it has the lack of a DC input jack and as well as it can also act as hrd and the virtual com Port device and the applications of ardino micro are it is used for USB joystick then in electric bike then Windows PC lock and unlock application also creating the wireless keyboard as well as the automatic peel
08:30 - 09:00 dispenser and the USB trackpad next is your ardino zero ardino zero is much more powerful and feature Rich than you know right it is powered with ATL's samd21 MCU which is a 32bit arm processor and another Advantage is that it has embedded debugger so no need of external debugger it embedded debugger is known as your edbg applications of r z r for hobby projects
09:00 - 09:30 anybody can use it power supply systems iot applications instrumentation as well as some display systems now in next videos you will see various practical approaches where we will be using ardino Uno so that's why I'm concentrating on ardino Uno only so as I have told that it is a microcontroller board based at Mega 328 and at Mega 328 has the flash memory of 32 kiloby and with5 KB is used for boot loader purposes it
09:30 - 10:00 has 2 KB of static RAM and 1 KB of eom that is known as your Electrical uh erasable prom and it is a one kind of single chip microcontroller formed with atml within the mega AVR family and the architecture is basically the 8bit risk processor code that is reduced instruction set computer processor code uh uh you must be seeing that in atga
10:00 - 10:30 328 this is the actually pin diagram of atga 328 as I have told that 14 are the digital input output pins out of that uh from 2 to6 and from 11 to 19 so those pins are used for the digital input output first pins is your reset pins and similarly some pins are used for the for example two and three so this uh number two and three are used for the receiving
10:30 - 11:00 or the transmission purposes and four and five these are used for the uh interrupts as well as if we want to give the voltage that means highest voltage 5 volt if you want to give then VCC pin is used and for the negative ground purposes we use the uh eight pin that is your ground pin and also there are two pins specially 9 and 10 these are for the crystal oscillator I will tell you that what is the purpose of the crystal
11:00 - 11:30 oscillator in the right hand side if you see that PIN number from 23 to 28 that is your pc0 to pc5 the six pins are known as your analog pins and you must be seeing I have written that ADC 5 ADC 4 that means analog pins it will it will input the analog signal and with this it will be converting into the digital signal and finally it will be processed in the controller and the three extra
11:30 - 12:00 pins we have used one is known as gnd that is your ground and ARF that is your reference voltage a VCC that is a means that these voltages are used for the ADC purposes besides this you must be seeing 19 18 17 16 uh these are used for special purpose uh for example 19th pin is used for sck that is your serial clock then 18th pin is used for miso that is your master in and slave out
12:00 - 12:30 then 17th pin is used for MOSI that is Master out and slave in and uh uh in 16th pin it is used for SS that is your slave select and these details have been given here as I have told that the ninth and 10th these are used for the crystal oscillator and the Crystal oscillator as I have told this is to provide the clock pulse to the atga chip clock pulse is needed for the synchron ization so that communication can occur in synchrony
12:30 - 13:00 between the at Mega chip and the device that is connected to and as I have told that these have the two pins mainly VCC and ground because of power if you want to give power uh to the uh uh chip or the controller then you have to use this two pins that is your VCC and the ground besides this we have the ADC that is your analog to digital converter as I have told six analog input output pins are there so that the analog data can be
13:00 - 13:30 in and the digital data can be out the ADC has three pins for its function avcc ARF and gnd avcc is the power supply that is your positive voltage that only for adcs it is used ADC needs some its own power supply in order to work so gnd is the power supply ground and ARF is the reference voltage that ADC uses to convert the analog signal to the
13:30 - 14:00 corresponding digital value that means it is it is working as a threshold value thank you so much and up to this we have learned about the introduction to ardino and the different types of ardino boards and specifically uh we have learned about the at Mega 328 the pin diagram of at Mega 328 and in the next uh PP next presentation or the next video we will learn about the ardino board itself and
14:00 - 14:30 the pin diagram of ardino board thank you so [Music] much
