Arduino has been a revolution ever since it struck the market. Arduino or Genuino (as known in some places), has been a very lucrative option for students designing their first projects. This increase in interest is causing a lot of people to tinker with technology themselves. We compiled a list of 20 Arduino projects that would be cool to design. If you have an Arduino lying around or are planning to buy one, these should come in handy. All you need is an Arduino board and some basic electronics supplies.

Robotics with Arduino
Tree climbing robot
This robotic project goes up a tree with ease. Unlike Naruto, this Sasuke (Ref. Naruto anime) keeps climbing a tree and this goes all the way. Trees with long stalk and no branches could be very well scaled with this little bugger. Build it and see it go all the way.

Fire breathing robot
For this next one, we would not advise taking it up at home, but at a safe and secure environment with zero flammable components. A flamethrower is underrated, using Arduino, you can also build a fire breathing animal. Makers of this project build it into a horse, but the final design is up to you. Khaleesi had dragons which breathed fire, you could have a horse. Hephaestus would be proud…

This next project takes dancing at your fingertips to the next level. Using Arduino, the designer could make an animatronic hand, that can be controlled by a user wearing specially designed gloves. Added advantage, it’s wireless. So, keep the animated hand out in your garden, while wearing the glove and scare trick or treaters. Remember, Halloween’s coming…

Once you have all this electronic stuff around, you can’t let just about anybody into your workshop. This Fingerprint door lock helps you in keeping unwanted people away from your workshop. You want some engineer to access the workshop, you can add his credentials to the database and he would have access as well.
This project is available at: Fingerprint Lock
Secret knock detector
If updating the fingerprint sensor becomes tiring for you, there is always another system of a secret door knock. However, things are not like the secret seven now. Using the Arduino project, you can turn your regular door lock into a smart door lock. A good opportunity to work with Morse code to come up with knocks. Or you could just “say friend and enter” (Ref. Lord of the rings). You could create multiple Arduino projects with similar rigs.

A variant of the secret knock detector could be a gumball machine that dispenses only to limited people. You could have a machine setup in your home and have fun with your family. You could also punish others by changing the knock. Kids not completing their chores, change the knock (just an idea).

This next James Bond device could be a double-edged sword. With the help of an Arduino, this surveillance camera is fits into a coffee cup. Every time you pretend to drink coffee, the tilt sensors in the module takes an image for you. Make sure the base of the cup is pointed in the right direction.

Arduino projects on Agriculture
Another idea would be to build a greenhouse for yourself. You can have your own kitchen garden build inside a wrapped enclosure. Mark Watney (Matt Damon in Martian) will be proud. Let’s look at the project before your shuttle malfunctions. In this slideshow, the designer takes you through the entire details about building an Arduino project. The project is easy to build and the software and hardware details are provided within the presentation. So, go ahead with building a greenhouse for yourself.

Automated plant watering system
Once you are all set with your greenhouse, how does an alarm system for watering your plants sound? This next project could be an addition to your greenhouse as well. You can use both Arduino projects together to have your own automated kitchen garden. This project is a simple and exciting plant watering system that you can build yourself in just a few hours. With efficient use of moisture sensor and downloadable component layout and source code, this could fit in perfectly for potted plants, be it on your terrace or the balcony or the front lawn. It works everywhere. This video takes you through a very similar system that would be very helpful in understanding the project.

Air quality controller
Some reports stated Bengaluru to be unliveable in the next 5 years. Top reason listed in the report was high air pollution. How about you build something for yourself that helps you in keeping the air clean at least in your home. The outside can be taken care by planting more trees, which is a longer process. You go ahead with building an air quality control system for yourself.

This list of Arduino projects starts off with an earthquake indicator. A highly-sensitive ADXL335 accelerometer is presented that can indicate vibrations. If motion is violent enough during an earthquake and crosses a certain threshold, a local alarm light (LED) glows, a buzzer sounds and a relay energises. With certain modifications, this can be turned into a knock-and-shake detector for ATMs, vehicles or door-break alarms as well.

Turn signalling jacket
Taking your zeal to make the air clean inside your apartment, we would also suggest you build this next jacket which signals left or right turning for two wheelers. Left or right turning indicators are often missing in bicycles, and most of the other people don’t use them. This jacket could come in handy for such people. The blinking LED’s indicate left or right turning movements.

This next project could come in handy the next time you mow the lawn. Playing with remote controlled small helicopters has always been funny. However, if you could get work done in the same play time, that would work out great. The grass would be cut, you could’ve had some fun. With this project, you could have a lawnmower, and a mini dump truck, into one. Work just became interesting.

Automatic tying shoelaces
Lawn mowing might be a bothersome task at times, but this next project is just straight up lazy. However, if you are that lazy, this next project might be the one for you. Statistics report a majority of people are uncomfortable with tying shoelaces, with about half of these don’t know how to. The effort taken to put your feet in tighten the laces and tie the knot might be too much. This next project built around Arduino does that for you. After Nike’s self-tying shoes, yours could be the one to hit the market. What do you think?

Washing machine alarm
A washing machine beeps once it finishes washing your clothes. However often this sound does not reach you due to many reasons. Imagine if you could have this alarm come to your mobile phone. This next project takes care of your washing machine alarms. You don’t have to listen to the beep of the machine, as the notification will show up in your mobile.

This project could be a simple addition to your night stand. Build an alarm clock using Arduino, and sleep tight. This trusty Arduino project would be an interesting project to try out. It could be easily made using the components already available with any tinkerer. Just go and get an Arduino already…

Walkie talkies have always fascinated me. I used to wonder why don’t people just use their phones. Turns out it makes much sense to use a walkie talkie for them. These are bi directional modules dedicated for conversation between just them. How about you make one for yourself? This next Arduino project uses a Bluetooth for communication. All you’ll need are basic electronics supplies and an Arduino board. Hopefully if your frequency crosses over with mine, we might talk?

How much does an inverter cost? A basic with a single battery costs about 20-25K INR. How about you just go about buying the battery and use this next Arduino project for your inverter. Money aside, you get to have fun while building it. Who knows, this very practical solution could generate interest in electronics for you.

This next one is for all the photographers out there. Splash photography is a very interesting form of art to lo at. The camera timing might not be able to get just right with a manual photographer at the helm. However, if you have an automated system operating that high-resolution camera for you, it truly works wonders. With this next Arduino project, you can design your very own rig and have a high-speed flash photography setup in no time.

The move to smart has now affected the rat trap too. This next project builds a rat trap using an Arduino. Seems like a suitable project to build and set up for those little thieves. Click through to prevent any more of these buggers from making anymore holes in your celery boxes or rice bags.
