Solar energy is so powerful that we make full use of this power almost everywhere like commercial use, agriculture, schools, government and residential solar power systems throughout the country. Besides nowadays many enthusiastic makers utilize even small solar panels to create various applied and awesome applications which are really an environmentally friendly,useful and  practical things for us.

I found that there are plenty of helpful projects about the use of solar panels so here I selected some

For most Pi makers, the Raspberry Pi is really a super platform for learning about IOT skills for its freedom of open source community and excellent community support. Today I wanna share five amazing raspberry pi IOT projects with dear pi makers. Raspberry Pi IoT Doorbell

This Raspberry Pi, IoT Doorbell is basically a simple smart Door Bell which takes

Sensors are widely used in our day-to-day life to detect events or changes in its environment and then provide a corresponding output. Besides sensors share abundant applications including manufacturing and machinery, airplanes and aerospace, cars, medicine,robotics and so on. To be specific, today I wanna introduce arduino projects on light sensor and color sensor which could be seen every here and there in scientific applications and in everyday consumer products. Nowadays you can see applications on light sensor  like a garage door opener,a burglary alarm, TVs,computers and wireless phones etc. Arduino Sunflower - an Electronic Sundancer This project

Nowadays Elecrow has increased many kinds of new products, welcome to take actions to find whether there is one that catches your ideas of creativity ! A7 GPRS+GSM+GPS Shield New added GPS function compared with A6 GPRS/GSM Shield to make a simple phone or more

An analog temperature sensor is a chip using a solid-state technique to determine the temperature and tell you what the ambient temperature is ! By precisely amplifying the voltage change, it is easy to generate an analog signal that is directly proportional to temperature. How to Set Up the DHT11 Humidity and Temperature Sensor on an Arduino To this project, you could get how the DHT11 measures humidity and how to connect the DHT11 to the Arduino and give you some example code so you can use the DHT11 in your own projects.

Robot, depended by many areas, has already taken up rather essential places to human beings for its great difference. Have you ever tried to make a robot with useful tutorials? And here I just gonna share you two nice and careful projects. I wish they could help you make a difference too. Build a 4WD Arduino Robot   With a 4WD Mobile Platform for Arduino Smart Robot Car, we could build a four-wheeled robot that can drive around and avoid obstacles. To begin with, you are supposed to attach the motors and the H bridge to the lower part of the chassis. First, attach the four metal brackets to each motor using two long bolts and two nuts. The next step is to secure the H bridge to the chassis  and then you can start wiring up the power supply. Now that you have

NFC or Near Field Communication, a standard-based wireless connectivity technology, enables making transactions, exchanging digital content or connecting electronic devices with a simple touch. And it is compatible with hundreds of millions of smart phones, business cards and readers already deployed worldwide. Moreover, NFC is applied widely by quite a few areas for medical & health care and safety & security and others. For example, for medical & health care, it could be applied to medical,chemical and biological test labs, medication identification,equipment usage tracking and pharmaceutical research tracking and so on. For safety & security, it shares applications of tool drawers,home entries,car locks and office

Do you miss the gyro toys we love playing when we are young? Now this toy idea have changed to large new world with plenty of great inventions like the unmanned aerial vehicles. The gyroscope shares a variety of categories and it could be divided to sensing gyroscope and indicating gyroscope from its function. The sensing gyroscope is mainly applied to the flying automatic control system for movement control of flying objects while the indicating gyroscope is mainly used in driving and pilot meter to indicate directions. Follows please enjoy two videos, you could get more different about gyroscope from the videos. Tim Peake demonstrates gyroscope - BBC News
