PROTOTYPING INNOVATION

Our thoughts regarding physical mail and posts is that it is diminishing over time. But, still some of our important documents are still sent through physical mail. Most of have a post box out of our house, and some live in an apartment and that also have an array of post boxes of houses. What if we don't check our mail box regularly? A gentlemen was not a big fan of Physical mail, and one day a tax bill was sent to his home and it was rested in the post box for about a month. This man was not aware of this and resulted him to pay the bill immediately with a penalty. If he checked the mail box he could have saved some amount of his money and his temper. That gentlemen wanted to have a solution for this, but he doesn't like to check that post box every time. So, if we have an Arduino we have the solution. This system notifies the user whenever there is a mail and hence avoiding the need to check for mail frequently. This project is based on RF module (RF Transmit

Everybody want to be healthy, and people measure three main parameters to define them selves as healthy or not. Body temperature, blood pressure and heart rate are the very basic things we measure to in order to stay healthy. To measure the Heart beat rate we can simply hold ones wrist and measure but, it is not that practical. Other way is to use a heart rate monitor, but they are quite expensive. As hobbyist and engineers we planned to create a Heart rate monitor using Arduino. A Heartbeat sensor is used to create this Heart rate monitor. This project was brought to us by a Bio Medical enthusiast, and he wanted to go an extra mile with this project. The sensor used in this project is a Hearbeat sensor which is compatible with Arduino. Heart beat sensor is available in may of the devices that we use in our day to day activities such as wrist watch, smart phone, chest strap and etc. Heart beat sensor consist of two parts as shown in the figure below, This sensor have
