Currently, in the market, a large number of GPS projects are distributed. You might be wondering what is different here? Well, the GPS receiver we are talking about is solely based on AVR- microcontroller. The project collects information from the satellite and so is more practical than other systems that demand wireless network connections as cellphones or Internet to operate. This GPS receiver system is a boon to remote areas and can be used as a base to work in other research areas. It works with the satellite to track…

Whenever we thought about distance measurement, an image of a circuit designed using an ultrasonic sensor is formed in our minds. But today we are going to present here a distance measurement project using the GPS (Global Positioning Measurement) module. The project named DIY Distance Measurement uses GPS and ATmega328 which measure the distance between two positions using the haversine formula. The start point is the position where switch SW1 (Reading Switch) is pressed and the endpoint is the position when switch SW2 is pressed (Switch Switch). Thus, the circuit…

The DIY project Digital compass posted here utilizes an OLED display to show the direction (i.e. north). Another feature of this project is, it shows real data and time. DIY Digital Compass using ATmega8 A conventional compass utilizes a needle or a dial kept inside a compass rose. The conventional compass work on the principle of the earth’s magnetic field. But the projects DIY Digital Compass using ATmega8 posted here use the sun position to show the direction, unlike the magnetic field. Thus, this DIY Digital Compass is not affected…

We often visit to restaurant for food and drink, there we see a waiter came and ask for order. The most annoying part is waiter wait while we are choosing items for menu. At the time of pick hour customer increase, requires more manpower and as a result the situation becomes annoying and expensive too. In order to solve these problem, here we had design a simple automation system called restaurant menu ordering system based on 8-bit microcontroller ATmega8. Different concept of digital menu ordering system has flourished along with…

There are various types of circuit used to indicate the temperature and humidity of fridge but it cannot measure relative humidity accurately. Because at the time of door opening of fridge relative humidity will rise or fall due to moister of surrounding. Thus, we had posted here “Wireless Temperature and Humidity Indicator for Fridge”. Here, we had posted a simple, small and handy wireless device which is used to measure temperature, humidity and relative humidity from inside the fridge. The circuit posted here used RF technology to transmit and receive…

The system “GPS Navigator Circuit using ATmega 16” is implemented to detect the position/location of anything under consideration, and hence it is suited for navigation activities. Introduction to GPS Navigator Circuit using ATmega 16 The term GPS has been so popular in recent times. The credit for its quick recognition is due to the list of multiple features this system offers. Elaborated as a Global positioning system (GPS) it has already been established as a reliable technology that has made our lives much easier. Just with the involvement of GPS, we…

The project GPS and GSM-based Vehicle Tracking System uses Global Positioning System (GPS) and global system for mobile communication (GSM), which makes this project more economic than implementing a communication system through GPS satellites in a two-way GPS communication system. Introduction to GPS and GSM based Vehicle Tracking System Tracking has now been a recent trend followed everywhere. This process helps us to collect details and at the same time prevent robbery of devices being tracked. The project ‘GPS and GSM based Vehicle Tracking System’ which employs a microcontroller as its…
