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.
If you haven’t check on the first part on RF module explanation, you might want to read it before proceed with RF using library. Here we going to discuss how to implement VirtualWire library with low cost RF module. VirtualWire library does not use the Arduino UART pin (digital pin 0 and digital pin 1).
You can download the VirtualWire library here.
Before we look into the code, let us see some of the functions.
Ever wonder how to implement wireless control on your project without spending too much of money? It is possible with cheap radio frequency (RF) module, consists of transmitter (Tx) and receiver (Rx). The RF module has to be used in pairs which are of the same frequency. Frequency of low cost RF module available are 315MHz and 433MHz.
I’m gonna share one of the project I had in my course subject, Microprocessor here. The title of my project is GPS sensor. So I was required to interface with GPS sensor by using Intel 8085 microprocessor. The language used is assembly language.
