- 3. WHAT IS ARDUINO 3 ►Arduino is a microcontroller based open source electronic Prototyping board which can be programmed with an Easy-to-use Arduino IDE. ► Arduino consists of both a Physical programmable circuit Board and a piece of software or IDE. The Arduino IDE uses a Simplified version of C++ making it easier to learn.
- 4. THE MAJOR COMPONENTSOF THE ARDUINO UNO BOARD ARE THE FOLLOWING POWER PORT 4 USB Connector MICRO CONTROLLER ANALOG INPUT PINS DIGITAL PINS
- 5. CRYSTAL OSCILLATOR 5 Reset USBINTERFACE CHIP TX RX LEDS THE MAJOR COMPONENTS OF THE ARDUINO UNO BOARD ARE THE FOLLOWING
- 6. Pitch Deck 6 USBConnector ► This is a printer USB port used to load a program From the Arduino IDE onto the Arduino board ► The board can also be powered through this port
- 7. 7 Power port ► TheArduino board can be powered through a AC-to-DC adapter or a battery ► The power source can be connected by plugging in a 2.1 mm central-positive plug into the power jack of the board ► The Arduino UNO board operate at a voltage of 5 volts, but it can withstand a maximum voltage of 20 volts
- 8. Pitch Deck 8 MicroController ► It is the most prominently visible black rectangular chip With 28 pins. Think of it as the brain of your Arduino ► The microcontroller used on the UNO board is Atmega328P By Atmel ( a major microcontroller manufacturer)
- 9. Pitch Deck 9 MicroController ► Atmega328P has the following components in it ► CPU: It controls everything that goes on within the device. It fetches The program instructions from flash memory and runs It with the help of RAM ► RAM of 2KB. This is runtime memory ► Flash memory of 32KB. The program loaded from the Arduino IDE is stored memory
- 10. Pitch Deck 10 AnalogInput Pins ► Arduino UNO board has 6 analog pins labeled “Analog 0 to 5.”These pins can read the signal from an analog sensor such as a temperature sensor and convert it into a digital value for system understanding
- 11. 11 ► You canfind these pins labeled “Digital 0 to 13.”These pins can be used as either input or output pins. When used as output, these pins act as a power supply source for the components connected to it and when used as inputs pins, they read the signal from the component connected to them Digital Pins
- 12. 12 ► When thisswitch is clicked it sends a logical pulse to the reset pin of the Microcontroller and now runs the program again from the start. Reset Pins
- 13. ► This isa quartz crystal oscillator which ticks 16 million times a second. On each tick, the microcontroller performs One operation, for example, addition, subtraction, etc.. crystal oscillator
- 14. ► Think ofthis as a signal translator. It converts signals in the USB level to a level that an Arduino UNO board understands. usb interface chip
- 15. ► TX standsfor transmit, and RX for receive. These are indicator LEDs which blink whenever the UNO board is transmitting or receiving data TX RX LEDs
