Arduino Soil moisture sensor

Mobile Control Soil Moisture

              The Mobile Controlled soil checker helps the presence of water in the soil, which could be controlled with the help of Smart phones. The application which is in Smart phone allows it to control the movement of vehicle and also check the presence of water in the soil. The vehicle could be controlled in certain directions such that Front, Back, Left, Right. The servo placed in help the control the movement of soil moisture sensor and soil moisture sensor checks the water presence. The serial monitor in mobile helps in monitoring the vehicle movement and also water presence in the soil.

Apparatus required

1)    Arduino               
2)    Motor Shield                          
3)    Hc-05bluetooth module          
4)    Soil moisture sensor               
5)    Servo                                      
6)    Chasser and Motors                             

*Click the above things to buy it.

Connection

·        Connect Arduino to the motor shield and connect the two motors to  the motor shield with respect to source code
·        Connect the servo with the motor shield in the servo port with respect to source code.
·        Connect the soil moisture sensor output to the A0 and vcc to +5V and Ground to the Ground pin.
·        Connect the Bluetooth module TX pin to Arduino RX pin and the Bluetooth RX pin to Arduino TX pin and +5V and Ground to the Ground pin.

                  Check out these photos to know its working
                               


                     The Black box which allows to knows the movement and control of the vehicles. The arrows allows it for control of directions.

 Up = 1      Left = 2    Stop = 3     Right = 4    Back = 5     Soil Checker = 6

 *Data which is sent from mobile application to HC-05 Bluetooth module when respective buttons are pressed.

What if you could control the Internet

At present situation internet is the basic need for us, we are using the internet for many purposes from medicine to aerospace internet is used and helps in day to day life activates. Internet is spread out in all the areas and we could say it is the most powerful tool in the world, if you got a chance to control the internet what will you do.                                                Image Credit : Internet In general, more than 5 billion google searches are done all over the world and millions of hours videos are watches in facebook and YouTube daily. What if you got a chance to control the internet, whether it is possible to control the internet, the internet is actually controlled with the help of 7 keys and by 14 peoples all around the world. They maintain the DNS which helps in accessing the internet all around the world. The DNS helps in accessing ...

ARDUINO KEYPAD LOCK SECURITY SYSTEM WITH SERVO MOTOR

                    ARDUINO KEYPAD LOCK SECURITY SYSTEM WITH SERVO MOTOR ARDUINO:          Arduino is Basic system which is used for the controlling various system that does lots of work.The arduino develope in 2003,the arduino is basically a microcontroling unit the code return in the form 8 bit ,32 bit which is return in the language of C and C++`The RAM in arduino is SRAM. KEYPAD LOCK:                       A Keypad Lock is the microcontrolled Security System in which it can be controlled which is contolled by the keypad which is 4*4 matrix and we could be secured with that.Here is the simple project with that we can do the keypad security system.

Creating Artificial Planet

Already our Earth is loosing the habitable tendency due to the deforestation, Climate changes, etc. These all causes our Earth as inhabitable planet, for life better we should move into another planet to move into another planet we could create our own planet. But, it is possible to build a planet as like Earth with Atmosphere, Air, Water, Moderate Temperature, Gravity, etc. Theoretically, it is said we could build a planet like Earth. We could build our own planet right in our solar system for constant temperature as we get in our planet “Earth”. We could probably use asteroids in our solar system to build our artificial planet, but we are having only lower amount of asteroids in our solar system so we cannot build a planet as we expected so we are going to use OORT CLOUD to build our Artificial Planet but problem with this OORT CLOUD is it is so far from our Earth, we haven’t still invented that fast vehicle to bring that materials here, so this case could not help us. We have ...
