Top 12 Arduino Project Ideas

Arduino Project Ideas

A guide for Arduino Project Ideas and exciting projects for beginners and engineering students.

Arduino is an open source Micro-controller board. It is based on Microchip ATMega328P Micro-controller developed by Arduino.cc. The board has sets of analog and digital input/output (I/O) pins that can interface with various expansion boards and other circuits. Arduino has 6 analog pins, 14 digital pins, and it can be programmed using the Arduino IDE (Integrated development environment) via a type B USB cable. It accepts the voltages between 7 and 20 volts and powers up by USB cable or a 9V battery. Moreover the hardware reference design is distributed under a Creative Commons Attribution Share-Alike 2.5 Licence which is available on the Arduino website. The production files and layout for some hardware versions is also available. Arduino UNO version 1.0 board is first in the series of USB Arduino boards and reference model for Arduino platform. The ATmega328 on the Arduino Uno comes pre-programmed with a bootloader which allows to upload new code to it without the use of an external hardware programmer.It communicates using the original STK500 protocol. The Arduino UNO 1.0 does not use the FTDI USB-to-serial driver chip. Instead, it uses the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. In conclusion, Arduino UNO has a wide variety of applications with excellent results.

General Pin functions

PIN FUNCTION
LED There is a built-in LED driven by digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off.
VIN The input voltage to the Arduino/Genuino board when it’s using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
5V  This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 – 20V), the USB connector (5V), or the VIN pin of the board (7-20V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage the board.
3V3 A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 m
IOREF This pin on the Arduino/Genuino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs to work with the 5V or 3.3V.
GND Ground pins.
Reset Typically used to add a reset button to shields which block the one on the board.


Special Pin Functions

Each of the 14 digital pins and 6 Analog pins on Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. These pins operate at 5 volts. Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor ( by default it is disconnected) of 20-50k ohm. A maximum of 40mA is the value that must not be exceeded on any I/O pin to avoid permanent damage to the micro-controller. The Arduino Uno has 6 analog inputs, labeled as A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). While by default they measure from ground to 5 volts, it is possible to change the upper end of their range using the AREF pin and the analog Reference() function.

In addition, some pins have specialized functions

PIN FUNCTION
External Interrupts pins 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
Serial pins 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip.
PWM (Pulse Width Modulation) 3, 5, 6, 9, 10, and 11 Can provide 8-bit PWM output with the analog Write() function.
SPI (Serial Peripheral Interface) 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication using the SPI library.
TWI (Two Wire Interface) A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library.
AREF (Analog REFerence) Reference voltage for the analog inputs.
