Do you know Arduino borrowed its name from a nearby watering hole called Bar di Re Arduino where it was first developed in Italy? See this infographics first, created by Make: magazine.
It is 10 years after its appearance and by now we all know the super popularity of Arduino – the first open-source hardware and software combination platform that millions enthusiasts as well as professionals all around the globe uses for making their electronics projects prototypes. It includes microcontrollers that can receive various inputs from different custom devices such as a light or pressure sensor.

Any Arduino board generally includes some flavour of microcotrollers manufactured by Atmel, such as Atmel 8, 16 or 32-bit AVR microcontroller. Nowadays Arduino board is manufactured by several manufacturers and they also uses different microcontrollers.
In this article, we shall see an overview of fifteen Arduino projects that will spark your interest on this easy and user-friendly platform. Please click on any headline to go to the project page. They will open in new window so that you do not loose this article page.
1. An ARDUINO based JPEG Camera with IR and PIR
Project by Boris Landoni from Open – Electronics dot org.
Let’s equip Arduino with a serial-interface JPEG Camera with IR and try two applications: the first one saves shots (on a SD-card) at regular intervals while the second uses a PIR sensor to detect intrusions and photograph what happens.
Recently, miniaturized cameras with serial communication interface have been launched on the market. Compared to traditional cameras, they offer easier integration with Arduino or other microcontroller-based boards.
This article will show how to use this camera in two different Arduino projects: the first creates a timing system to take pictures on specific intervals, storing them on the SD-card, while the second is an automatic surveillance system activated only if the special PIR sensor (Passive Infrared Radar) detects a warm object moving in the camera view field. In practice, this second application is a time-lapse video surveillance device that records what happens in a room, activated by the detection of moving people or vehicles. Of course, the PIR detection area must match the same camera angle so that the captured images effectively show the triggering “foe”.
2. Bluetooth enabled Door locker using Arduino
Project by Frank Donald from Gadgetronicx dot com.
DIY Arduino-based lockers can be found plenty in the internet where keypad was used to feed lock input. But this Bluetooth enabled Door locker uses Bluetooth as a medium to connect with the locker and your smartphone to feed input credentials. This locker allows you to lock/unlock your locker without physical touch when you are within the range of Bluetooth communication.
Arduino is the heart of this locker system and HC-05 module provides the Bluetooth connectivity for the Arduino. A relay has been added to act as an activator for the E-locker in the above design. You may replace it with any other electronic activator or door activator if you are going to use it for doors. If that’s the case alter the design in such a way that the system is provided with enough power to drive the activator.
3. Heart Pulse Alarm (HPA)
Project by Murad M from his Blog.
The HPA (Heart Pulse Alarm) is a portable device that measures the pulse rate and the body temperature. If the device receives an up normal heart pulse, it will send a message to paramedics to act quickly.
4. Arduino based remote controlled lights
Project by Frank Donald from Gadgetronicx dot com.
Christmas is just around the corner and its time to start planning things to lighten up this festive season. Today you are about to see building of Arduino based Remote controlled lights with adjustable lighting effects. The coolest thing about this project is controlling the effects of LED lighting using a typical household Remote and Arduino. This eliminates the primitive way of using pot to control LED effects and go wireless.
5. Make a huge 7-segment digital clock with Arduino
Project by Matt Wes from Instructables dot com.
One of the benefits of the Arduino development platform is the ease of making an accurate clock, and the following example by Instructables member Matt_wes is not only easy to make but also quite useful.

Instead of making do with pocket-sized LED displays, this clock uses digits that are 16 cm tall and would be visible from quite a distance away. Thanks to the power required for each segment, they are switched via MOSFETS to deal with the current.
In the next page, we start with another Big wall clock followed by a Lie Detector.
