Arduino Uno Projects for Beginners and Engineering Students

Arduino UNO is a Microcontroller developed using ATmega328P. It has 14 digital I/O pins. From among these 14 pins, 6 are used for PWM output. Beside these Uno also has 6 analog inputs, a 16 MHz quartz crystal. It also contains a USB connection along with a power jack, an ICSP header, and a reset button. This Uno can be viewed as a plug and play device. To get started, one simply has to connect it to the computer using a USB connection or can power it using AC-DC adapter or battery. For programming an Arduino Uno, an Arduino IDE is required. To work on Arduino, one has to install this IDE on the computer and write programs using it. The ATmega328P is preprogrammed with the boot loader. So, one can upload new code to the Uno without the use of an external programmer.

Arduino Uno Projects for Beginners

Some of the exciting Arduino projects for the beginners are listed below. Once the Arduino software IDE is installed, connect the Arduino UNO board to the computer using a USB connection. In the IDE go to the TOOLS and then BOARD and select the board from the drop list. To select the port, go to the TOOLS, then from PORT select the port that says ARDUINO.

Blink an LED

The hardware parts required are

  • Arduino UNO board.
  • Breadboard.
  • Jumper Wires.
  • LED.
  • 220Ω Resistor.
  • USB cable.

Step 1: Insert the Black jumper wire into the ground pin on the Arduino and the other end to the ground on the breadboard .i.e. row 15.

Step 2: Insert the red jumper wire to the pin 13 of the Arduino and the other end to the F column and 7th row of the breadboard.

Step 3: Place the long end of the LED into the 7th row of the H column of the breadboard.

Step 4: Place the short leg of the LED into the 4th row of the H column of the breadboard.

Step 5: Place one end of the resistor in the Ground rail at 4th row of the breadboard and the other end into the 4th row I column of the breadboard. Now connect the Arduino the computer using USB.

After making all the connections now to program the Uno, open the IDE. Arduino IDE has some built-in programs, which one can simply copy and use. To blink an LED program open FILE then choose the EXAMPLES option, then go to BASICS option and then choose the BLINK option. This will open the Blink LED program.

Use the verify button, given at the top left of the IDE box, to check the program the errors by compiling. Once it indicates “ Done Compiling” the program is ready to be used. Click the upload button to upload the program into Arduino board.

The built-in LED of the board flash rapidly for a few seconds and the program will start to execute. If there are no errors, the LED on the breadboard will Turn ON for a second and then Turn OFF for a second and continue in the loop.

In the same way, as described above by choosing a different code and customizing the Hardware required one can work on Uno hustle free.

Some of the other basic projects are

  1. Designing a push button to turn ON and OFF a LED.
  2. Designing a potentiometer to change the resistance values of an LED.
  3. using the PWM pins on Arduino to increase or decrease the intensity of the LED.
  4. Design a scrolling LED loop where 6 LEDs blink, one at a time, back and forth.
  5. Designing a Bar graph by using Potentiometer and LEDs.

4WD Smart Robot Car

In this project, a Smart Robot Car is designed that can avoid obstacles and follow the given directions to reach the destination. This car can function automatically or manually by using the Bluetooth module. The hardware used for this project is an Arduino UNO, Dual H bridge motor driver, Ultrasonic sensor, Bluetooth module, Contact avoidance sensor, Line Tracking sensor, and Li-Ion battery.

Ultrasonic Range Detector

In this project, an Ultrasonic sensor is used with Arduino to measure distance without using a ruler. Similar to the method used by bats to measure distance by using echo, here the ultrasonic transmitters emit the ultrasonic sound and measure the distance by calculating the time it has taken for the ultrasonic sound to hit the object and return back to the Ultrasonic receiver.
