Arduino Project Ideas For Intermediate-Level Students

Following are the best Arduino project ideas for intermediate-level students.

6. Considerations

Before peeking at our choices, let’s figure out the standards we used to make our selections:

  • Challenging: All these Arduino projects will present a genuine DIY experience, whether it’s the formation process, the program needed, the number of elements, math, or the theory behind the Arduino project.
  • Cheap: Although all Arduino projects need materials to be bought, the instructions are complimentary.
  • Replicable: All Arduino projects are picked up to include a code, bill of materials (BOM), and required instructions for wiring and gathering to bring the project out.

7. LED Cube

The LED cube is included in the best arduino project ideas. Cubes of LED lights are an excellent activity for people of all skill levels. It is solved by counting the number of LEDs along each cube’s edge. It also takes a steady touch and greater complexity to construct the cube as additional LEDs are added.

8. Writing Machine

Nowadays, a CNC machine can perform almost anything thanks to its expanding capabilities. You may also use this device to produce an ideal essay. Aside from flawless handwriting, there is no assurance that the content will be worthwhile.

This ingenious apparatus operates at a constant height and requires little traction since handwriting generates so little friction. A timing belt drives the pen in exact XY motions, and the system includes an on/off, up/down action in the pen tool head for lifting the needle off the paper.

Arduino Project Ideas For Advance Level Students 

Let’s know the following best Arduino project ideas for Advance level students.

9. Levitation System

The inventor suggests using proportional-integral-derivative (PID) control. It continuously varies current to maintain a specific temperature or other target value to keep the pot afloat in a steady position. Moreover, the levitation system is included in the best arduino project ideas category. The PID controls two solenoids—one in the vessel’s upper portion and another at its lower level. PID control adjusts the induced magnetic current produced by feeding electricity via a solenoid, maintaining the pot at a fixed height above the ground.

10. Mini-Oscilloscope

It is also included in the arduino project ideas. Now it’s time for a theoretical challenge. You don’t need a deep understanding of electronics to build something similar to someone else’s work, but if you want to make something completely new, you should hit the books.

Some electronic engineers specialize in just one area, signal handling. Learning a great deal about your system is possible by observing it and interpreting the signals it sends and receives.

To read and show electrical waves, you need an oscilloscope. Sine waves, triangle waves, and rectangle waves may all be revealed. It is of paramount significance in electronics and signal processing.
