The voltage provided by the power jack can be accessed through this pin. Vin => It is the input voltage supplied to the board which ranges from 7V to 20V.Setting this pin to LOW will reset the board. Reset => This pin is used to reset the board.GND =>There are 5 ground pins available on the board which makes it useful when more than one ground pins are required for the project.While another voltage regulation is provided by 3.3V pin. It can be obtained from Vin of the board or USB cable or another regulated 5V voltage supply. This regulated power supply powers up the controller and other components on the board.
#Arduino mega serial port interrupt code#
code that identifies which satellite is transmitting information. A GPS signal contains 3 different types of information However, modern receivers are more sensitive and can usually track through houses. The signals travel by line of sight, meaning they will pass through clouds, glass and plastic but will not go through most solid objects, such as buildings and mountains. GPS satellites transmit at least 2 low-power radio signals. Once your position has been determined, the GPS unit can calculate other information, such as
Generally, a GPS receiver will track 8 or more satellites, but that depends on the time of day and where you are on the earth. With 4 or more satellites, the receiver can determine your 3-D position (latitude, longitude and altitude). To calculate your 2-D position (latitude and longitude) and track movement, a GPS receiver must be locked on to the signal of at least 3 satellites. With distance measurements from a few more satellites, the receiver can determine a user's position and display it. Essentially, the GPS receiver measures the distance to each satellite by the amount of time it takes to receive a transmitted signal. GPS receivers use this information and trilateration to calculate a user's exact location. Each satellite transmits a unique signal and orbital parameters that allow GPS devices to decode and compute the precise location of the satellite. GPS satellites circle the Earth twice a day in a precise orbit. GPS works in any weather conditions, anywhere in the world, 24 hours a day, with no subscription fees or setup charges. The Global Positioning System (GPS) is a satellite-based navigation system made up of at least 24 satellites. What I found is there is no tutorial for interfacing of Arduino Mega with NEO-6M GPS module so I decided to make one.
