In my previous article, GPS Bee Kit (Part 1), I have shown a few methods how to read NMEA messages directly from your computer without an Arduino. In this post, I will explain some basics of the NMEA message and how to make a simple interface with Arduino and GPE Bee Kit.
Global Positioning System (GPS) is a space based satellite navigation system that provides location and time information. Initially, GPS only available for military used in tracking, but now it is available to everyone. GPS is widely used in application such as military, robotics, astronomy and etc. But we can also see the application of GPS in our daily life such as navigation system in advance car or mobile phone with built in GPS. A basic GPS provides information such as location (latitude and longitude), altitude, speed, and time.
Have you ever wondered how people made their projects controlling tons of LEDs with just a single Arduino? Controlling all the LEDs individually requires a lot of pins. So, now I am going to introduce you to shift register. In this tutorial the shift register that we are going to use is 74HC595, 8 bit shift register. By using shift register, you expanded a lot of output pins from your Arduino, that is the best part! Continue reading “74HC595 8 bit Shift Register”
