What is Arduino? Projects using Arduino

What is Arduino?

Arduino is a form of electronics platform which is based on user-friendly hardware and software.  Arduino boards are capable of reading inputs and converting them into output. One can instruct one’s board about what to do by sending out instructions to the microcontroller present on the board.

Over the past couple of years, Arduino has been the base of several projects ranging from day-to-day objects to complicated scientific equipment. A global community of creators including artists, students, programmers, hobbyists, and professionals have developed the Arduino and have increased the amount of knowledge accessible to creators alike.

Arduino was invented at the Ivrea Interaction Design Institute as an easy-to-use tool for quick prototyping. It was designed for students with no prior background in programming languages and electronics. Upon reaching a broader segment of society, the Arduino board started adapting according to modern needs and problems. It diversified its offers from basic 8-bit boards to products for wearable and 3-D printing. All Arduino boards are sourced openly hence users have the liberty to design them independently and tailor them according to their specific needs. 

Impressive examples of Arduino projects

The introduction of Arduino is revolutionary and has proved to be an amazing opportunity for creators to initiate their projects according to their needs. Some impressive examples of Arduino projects have been discussed below.

Arduino based Alcohol Sense Engine Lock & GPS

Drunk driving results in damaging road accidents globally. In most road accidents drivers are found to have excess alcohol concentration in their blood. Arduino is used to designing an alcohol sense system combined with GSM and GPS for transmission of location. This alcohol detection system also comprises an Arduino Uno board and an Mq-3 alcohol sensor for detection.

The system enables automatic detection of the concentration of alcohol present in the breath. Furthermore, a GPS along with GSM is used to send an SMS with the location of the driver to the concerned person in a scenario of alcohol detection higher than permissible limits. Simultaneously, the Arduino controller automatically halts the vehicle’s motor to prevent an accident.

Solar Powered Water Trash Collector

Although water is an indispensable resource, water pollution is one of the most damaging environmental threats that we experience today. Reverting the impact of water pollution is extremely difficult and can cost years to remove hazardous substances from the water bodies.

The solar-powered water trash collector is an innovative system that offers an automated way to deal with the issue of water pollution. It eliminates the requirement of manual labor hence making the process more time and cost-efficient. This floating trash collector removes the waste that gets accumulated on the water surface hence reducing water pollution. This is an Arduino-based project which is operated using an RC remote that can be maneuvered accordingly. Furthermore, DC pumps are used to provide direct control and arrange the motor for the steering. The boat is made self-sustainable by using two Solar panels to charge the battery. Garbage is collected by a net made up of a wire gauge.

3D Printing Used in Medicine

3D Printing in Medicine: The Need to Know

No, 3D printing is not a fad. It has come to stay. And it is only getting better.

While for consumers it is mostly used to make decorative objects or to replace parts when needed, many companies have already integrated it into their design process, creating useful prototypes in a matter of days.

But where 3D printing really shines is in medicine. This is not something from the “far future”, this is the state of the art.


Ever watched the famous Anime movie Ghost in the Shell? That about The Avengers : Age of Ultron – MCU? Where a conscious mind can be added to a body made of various metals assembled at a molecular level. We are getting there.

With 3D printing, you have a great balance between customization, cost, and production time. Although most of the materials available to consumers aren’t very strong, medical companies have access to many materials and technologies that when combined in unique ways create the platform that opens creative solutions to the challenges currently being faced, this includes 3D printers that use titanium.

Prosthetics are now becoming both more functional and more artistic, it is fast becoming easier, more cost effective and efficient to create and manufacture a unique one from the ground-up.


If instead of replacing a body part currently one needs to replace either a part of or an entire bone, 3D printing can help with bone replacement. As previously mentioned, there are 3D printers that can print titanium. Titanium is a bio-compatible material, meaning that human tissue can connect with it, instead of considering it a foreign body and rejecting it.

Traditional manufacturing methods tend to waste a lot of energy and are extremely inefficient, This is due to the process where the metal first needs to be melted at high heat in order to give it a shape using molds, which are too challenging and very expensive to create. Thereafter cutting and diamond polishing until the final form is achieved. Metal 3D printing just melts the metal powder directly into the desired shape, requiring only little polishing afterwards, so it is much cheaper.

This means that objects that require a lot of titanium, like bones, will be both cheaper and quicker to manufacture in the near future, even considering that titanium is one of the toughest and expensive metals we have access to.

Physical medical models

Surgeries is a rather difficult task. It becomes even more challenging considering that it is mostly a task where one does not know what to expect. Humans have a roughly consistent anatomy, but there is always an anomaly, a variation, especially when illnesses are involved. When attempting surgery that is critical for the life of the patient involved, there is no greater privilege, responsibility, and risk management. It makes one wonder why all medical professions are called a ‘practice’.

What if surgeons could practice the surgery on a customized model of the patient’s anatomy? That would surely make things easier, wouldn’t it?

With 3D printing, a CT scan of a body part can be transformed into reality. High-end 3D printers come in many different sizes and can use a multitude of materials and material colors, the ideal result will be as close to reality as possible. And it will keep getting better.

3D printing is here to stay and thankfully so. It is bound to make everything much faster and cheaper to create, the rate of technology acceleration is growing exponentially. It will not take long for it to reach that point and who knows, perhaps faster than expected.
