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. Besides 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 an 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. This article list outs Arduino Uno Projects for beginners and engineering students include the following.

Simple Arduino Uno Projects for Beginners

Blink an LED

The hardware parts required are

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

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 the 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 the 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.
