9 Crazy Arduino Projects You have Never Heard About (With Tutorials)

Selecting the crazy Arduino project might be the biggest hurdle when you are just starting out your Arduino career.

Don’t worry, it won’t be a hurdle now.

With a bit of work, and the right Arduino board. You can make your own projects that could be a great resource to enhance your skill set.

I gathered a lot of crazy Arduino projects and made a huge list of some of the best projects that you could use in your real life. Hand gesture-controlled robots using Arduino and Digital Alarm clocks are the best projects so far.

Arduino is a well-known open-source hardware board utilized by engineers, specialists, and producers to develop electronic projects and models simply.

It has different types of boards, and is easily available in the market. Every Arduino board is unique in its own way and you can use it according to your project requirement just like Arduino UNO, Arduino Nano, Arduino Mega, Arduino Lilypad, etc, all of which are based on the arrangement of AVR microcontrollers.

Building Arduino projects can deliver an extraordinary sense of fulfillment and skill, but oftentimes beginners don’t know where to start, and what should their first project be.

Don’t worry, by the end of this blog you will be able to make your own projects.

There are a few complex things that require thought when you are starting a project, and if you have no creator involvement, it can be very confusing.

For this reason, a list of 9 crazy Arduino projects for tenderfoots with instructional exercises that anybody can start!

Even a 14-year-old kid too.

Before we move on to the projects, you should how to select the best board, and it is as crucial as making a foundation in any house.

How to select the Arduino board that goes with your all projects?

My sister thought getting started with Arduino Lilypad would be a game changer and I wouldn’t need any other new boards to make a Digital Alarm Clock, and other projects, but she ended up buying the wrong one because that board is only used for wearable projects. That was a nightmare for her.

You might be thinking what Arduino board should I buy that fits in all of your projects?

You need to be more strategic when selecting the right board because you could end up ruining your project by selecting the wrong board.

The title Arduino is trademarked by the first obvious company in Italy. All compatible Arduino boards utilize a distinctive but see-alike trade name like Freeduino, Netduino, etc.

In case you need a cheaper elective of the Arduino, you’ll be able to continue to purchase the clone boards.

NOTE: But I won’t recommend you to buy these cheaper boards as they are almost equal in price, but the efficiency of their components might be lower than the original ones.

You can buy Arduino boards from many online places, but eBay, Amazon, and Sparkfun are some of the best online places to buy microcontroller boards. They are too accessible in your city’s neighborhood gadgets stores, so grant them a call and affirm the time recently going over.

Along with the Arduino Uno, which is the finest starter to the Arduino world, there are other microcontroller boards that can be found in the advertising. Since determinations change, you ought to select the board for your Arduino family.

To bring your Arduino projects to life or to step into the world of Arduino, it is superior to urge begun with the foremost commonly utilized board such as the Arduino UNO, Arduino MEGA, or the Arduino Scaled-down, as these have more noteworthy forums and arduino community accessible online than others.

Arduino UNO is famous for its little and basic Arduino projects depending upon your requirements and the good thing about it is; economical. Or on the off chance that you’ve got a requirement for the number of pins or serial communication gadgets to be processed with the same controller, you’ll go for the Arduino Mega.

NOTE: I would recommend you to use Arduino UNO if you are just starting out, it is simple, economical and easily available in the market, or you could buy it from Amazon.

1. Motion Following Motorized Camera Base

You might need two cameras at your main door to watch out for outdoor activities because your camera doesn’t move.

With a little work on the code, and calibrating the sensors; your camera will be able to detect motion and move whoever passes by. This could increase your security, and you could also watch out for your children’s activities in the backyard.

To illuminate this issue, I chose to form a movement tracking based on which I might connect the camera so it would naturally reposition itself to wherever the movement was identified.

How does motion following a motorized camera base work?

  • You utilized the Arduino UNO microcontroller for interfacing the different hardware and required to form the implanted framework come to life.
  • The PIR sensors come inconveniently to identify the movement of a person. You need to divide the full framework into 5 divisions and put each PIR sensor in each of the compartments.
  •  At whatever point, it recognizes movement in any one of the compartments the camera pivots to that compartment and brings in to see anybody who is displayed in that position.
  • You actualized this with the help of a persistent revolution servo which empowered us to have a 360-degree revolution extend.
  • You moreover, had 5 LEDs interfaces to the Arduino UNO where each was Driven and comparable to each of the 5 compartments.
  • The moment assignment that was handed was the task of confronting discovery and altering the camera to bring the confrontation within the show. So, you utilized an adaptable computer program sketchbook named Handling 3.2.3 and included the OpenCV library to empower the highlight of identifying faces.

What components do you need for Motion following Motorized Camera Base?

Following are the components you will need to make your own motion following a motorized camera.

  • Arduino UNO (A Microcontroller that would send signals to the camera)
  • Five PIR Sensors (It would sense the motion near the sensor and send the signal to the microcontroller)
  • Lipo Battery 7.4V (To power up the microcontroller)
  • Continuous rotation Servo
  • 180 Servo (It would help the camera to move)
  • Capacitors
  • Resistors
  • Web camera
  • LED

After collecting these components and applying the complete method given in the tutorial, you can make your motion following a motorized camera.

4. Motion-Sensing Alarm with KeyPad and Password

The caution actuates in 10 seconds after squeezing the A button. For identifying objects it employs an ultrasonic sensor, and once the caution distinguishes something, a buzzer begins emanating a sound. To halt the alert, you got to embed a 4 digits watchword. The preset secret numbers are 1234 but you too have the plausibility to alter it.

By squeezing the B button you enter the secret word alter menu where, to begin with. You ought to enter the current secret word to proceed and after that enter the unused 4 digits password. Once the watchword is changed, the following time you actuate the caution, and can halt the alarm by entering the unused watchword. If you enter an off-base secret word, you will get a message that you ought to attempt once more.

7. The alarm clock by Arduino

I outlined an Arduino-based Genuine Time Clock with an alert. A Genuine Time Clock or RTC may be a battery-powered clock that measures time indeed when there’s no outside control or the microcontroller is reprogrammed. An RTC shows a clock and calendar with all timekeeping functions. The battery, which is connected to the RTC could be a partitioned one and isn’t related or associated to the most control supply.

When the control is restored, RTC shows the genuine time independent of the length for which the control is off. Such a Genuine Time Clock is commonly found in computers and is regularly alluded to as fair CMOS (Complementary Metal Oxide Semiconductor). Most microcontrollers and chips have built-in clocks for keeping time. But they work as they were when the microcontroller is associated with the control supply.
