The Arduino is a cheap electronics board that allows you to make your own electronics without a ton of coding experience. We love the Arduino, but like any electronics project, coming up with ideas for what to build is tough. Whether you’re just looking for inspiration or just need a place to start, let’s take a look at ten of the coolest Arduino projects.
Top 10 Arduino projects are selected by our experts of RoboCircuits. These projects are available on YouTube. Links to these projects are given below you can check.

If you want to build a robot that moves across the ground, the normal options are wheels or legs of some kind. Maker “joesinstructables,” however, decided to do something a bit different. He created a versatile, slithering system, which he calls the “Lake Erie Mamba.”\n\nHe put a dozen Arduino Mega-controlled servos together in a reptile configuration to allow the robot to move via serpentine motion (like a normal snake), rectilinear motion (like a worm), or sidewinding (which snakes use in shifting terrain). It can also twist itself into a wheel and roll in this rather unnatural, though quite interesting way.
Built with an arduino nano and 4 HC-SR04 ultrasonic sensors. It uses ultrasonic waves to protect itself from being crashed by any obstacle or any wall. it uses four ultrasonic sensors on its each side which gives Arduino signals when it reaches its limit distance to any obstacle.
This system is proved highly helpful to avoid drone crashes. And even it will avoid the collision of human beings and drone which causes high injuries.

3. Otto Robot
Who is Otto?
An interactive robot that anyone can make!
What can Otto do?
Otto walks, dances, makes sounds and avoids obstacles.
Why Is Otto special?
Otto is completely open source, Arduino compatible, 3D printable, and with a social impact mission to create an inclusive environment for all kids.
Otto’s differences are in the assembled size (11cm x 7cm x12cm), cleaner integration of components and expressions. Using off the shelf and 3D printed parts, simple electronics connections (almost no welding required), and basic coding skills, you will be able to build your own cute Otto friend in as little as two hours!

One of [Dooievriend]’s friends recently pressed him into service to write software for a 3d spectrum analyzer/VU that he made. The VU is a fairly complex build: it’s made up of 1280 LEDs in a 16x16x5 matrix controlled by a PIC32 clocked at 80MHz. [Dooievriend] wrote some firmware for the PIC that uses a variation on a discrete Fourier transform to create a 3D VU effect.
When [Dooievriend] set out to design the audio analyzing portion of the firmware, his mind jumped to the discrete Fourier transform. This transform calculates the amplitude in a series of frequency bins in the audio—seemingly perfect for a VU. However, after some more research, [Dooievriend] decided to implement a constant Q transform. This transform is very similar to a Fourier transform, but it takes into account the logarithmic way that the human ear interprets sound.
[Dooievriend] started implementing the constant Q transform using an interrupt-based sampler, but he quickly ran into issues with slow floating-point math on his PIC32 (which doesn’t have a hardware floating-point unit). Thankfully he rewrote his code using fixed-point math, and the transform runs nearly real-time. Check out the video after the break to see the VU in action, and a second video that gives some details on the hardware build.
