Project Details for Turtle Robot

Project 1: Getting Started with ARDUINO

1)UNO Control Board

When it comes to using the UNO R3 as core of our robot, the UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with.

Well, let's at first have a look at this UNO R3 board.

	USB Connection Arduino board can be powered via USB connector. Or you can program the board via the USB port.
	DC Power Jack Arduino board can be supplied with power from the DC power jack
	Voltage Regulator To control the voltage provided to the Arduino board, as well as to stabilize the DC voltage used by the processor and other components.
	Crystal Oscillator How does Arduino calculate time? by using a crystal oscillator. The number printed on the top of the Arduino crystal is 16.000H9H. It tells us that the frequency is 16,000,000 Hertz or 16MHz.
	Arduino RESET You can reset your Arduino board, for example, start the program from the very beginning. Firstly, use the RESET button（17）. Or you can connect an external reset button to Arduino pin 5 labeled RESET
	Pin Header（3.3V，5V，GND，Vin 3.3V - provides 3.3V output voltage 5V - provides 5V output voltage Using 3.3 volts and 5 volts, most components can normally operate with Arduino board together. GND（Ground pins）- two GND headers on Arduino, each of which can be used for circuit ground. Vin - You can supply an external power (like AC power supply) through this pin to Arduino board.
	Analog Pins Arduino UNO board has 6 analog inputs, labeled A0 through A5. These pins can read the signal from analog sensors (such as humidity sensor or temperature sensor), and convert it into the digital value that can read by microcontrollers)
	Microcontroller Each Arduino board has its own microcontroller. You can regard it as the brain of your board. The main IC (integrated circuit) on the Arduino is slightly different from the panel pair. Microcontrollers are usually from ATMEL. Before you load a new program from the Arduino IDE, you must know what IC is on your board. This information can be checked at the top of IC.
	ICSP (In-Circuit Serial Programming) Header In most case, ICSP is the AVR, an Arduino micro-header consisting of MOSI, MISO, SCK, RESET, VCC, and GND.It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output.In fact, slave the output devices under the SPI bus host.
	Power LED Indicator Powering the Arduino, LED on means that your circuit board is correctly powered on. If LED is off, connection is wrong.
	TX and RX LED Onboard you can find two labels:　RX(receive ) and TX (transmit) First appear on digital pin 0 and 1 for serial communication; Besides, the RX LED on the board will flash in different speed when serial data is being transmitted. The flash speed depends on the baud rate set by board. And RX LED will also flash during the receiving process.
	Digital I/O Arduino UNO has 14 digital input/output pins (of which 6 can be used as PWM outputs). These pins can be configured as digital input pin to read the logic value (0 or 1). Or used as digital output pin to drive different modules like LED, relay, etc. The pin labeled “〜” can be used to generate PWM.
	AREF Reference voltage( 0-5V) for the analog inputs. Used with analogReference().

Installing Arduino IDE

When you get the UNO development board, first you should install the software and driver of Arduino. You can see all the Arduino software versions from the link below:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x
Or you can browse the ARDUINO website at this link, https://www.arduino.cc, pop up the following interface.


Then click the SOFTWARE on the browse bar, you will have two options ONLINE TOOLS and DOWNLOADS.


Click DOWNLOADS, it will appear the latest software version of ARDUINO 1.8.5 shown as below.


In this software page, on the right side you can see the version of development software for different operating systems. So ARDUINO has a rather powerful compatibility. You should download the software that is compatible with the operating system of your computer.
In our project, we will take WINDOWS system as an example here. There are also two options under Windows system, one is installed version, the other is non-installed version. For simple installed version, first click Windows Installer, you will get the following page.





This way you just need to click JUST DOWNLOAD, then click the downloaded file to install it.
For non-installed version, first click Windows ZIP file, you will also get the pop-up interface as the above figure.
Click JUST DOWNLOAD, and when the ZIP file is downloaded well to your computer, you can directly unzip the file and then click the icon of ARDUINO program to start it.
