 100 things Google announced at I/O'19 Another I/O is in the books! We played in sandboxes, watched eye-popping product demos and  listened to AI-powered music . But the fun isn’t over! In case you missed it, here are 100 announcements we made at I/O: Hardware 1.  Hold the phone! Our new smartphones— the Pixel 3a and Pixel 3a XL —hit the shelves this week, bringing together all the essential Google features at a lower price ($399 for the 5.6-inch display and $479 for the 6-inch model). 2.  Good things come in threes, like Pixel 3a’s color options. Choose from Purple-ish, Clearly White and Just Black. 3.  And no matter what color your phone is, it has the same great Pixel camera. Capture shots in portrait mode and HDR+, or use Night Sight to take magical photos in low light (think outdoor concerts, swanky restaurants or night hikes with friends). 4.  To add to the creativity, Time Lapse is coming to Pixel 3a. Soon you can capture an entire sunset within a fe

Days to go to complete 21 years Countdown

By vinod Kumar  Dec 20, 20 According to National Crime Records Bureau (NCRB), it is estimated that more than 1.2 lakh deaths have been caused because of fire accidents in India from 2010-2014. Even though there are a lot of precautions taken for Fire accidents, these natural/man-made disasters do occur now and then. In the event of a fire breakout, to rescue people and to put out the fire we are forced to use human resources which are not safe. With the advancement of technology especially in  Robotics  it is very much possible to replace humans with robots for fighting the fire. This would improve the efficiency of firefighters and would also prevent them from risking human lives. Today we are going to build a  Fire Fighting Robot using Arduino , which will automatically sense the fire and start the water pump In this project, we will learn how to build a  simple robot using Arduino  that could move towards the fire and pump out water around it to put down the fire.

Wireless notice board using Arduino and GSM module Wireless notice board  is very selective term for this project, as it has a very wide scope rather than just being a simple notice board. First we should understand the purpose of this project, in this system we can display a message or notice to some display device like LCD, and this message can be easily set or changed from anywhere in the world, just by using the  SMS facility  of your mobile handset. Whatever notice we want to display, just send the SMS of that text, with some prefix and suffix. This is very useful in Hotels, Malls, college, offices and can be used anywhere, even at home. Like you can set the message like “Do not disturb” at your hotel’s room gate, can set message at your home’s door step when you are away, and of course it is used as notice board in schools, colleges, cinema halls etc. And yes, it’s just not a simple Message board, the usefulness of this project is that you can set or change the message or no

      Voting machine using Arduino We all are quite familiar with voting machines, even we have covered few other electronic voting machine projects previously aan  using RFID and AVR microcontroller. In this project, we have used the arduino controller to create an  electronic voting machine Electronic voting machine has now replaced the traditional mechanism of ballot voting due to several advantages like security, automatic counting etc. The system consists of two units – the control unit and the user unit. The control unit consists of some control switches and status LED’s, and is handled by the presiding officer. The user unit provides voting facility and contains a matrix keypad, a memory IC and an LCD display. The system operates in three modes – the Idle mode, Voting mode and Counting mode. Each mode is identified by a status byte written in the EEPROM. In Ideal mode the machine is idle, that means the machine is ready to use. When the presiding officer press the ST
