Introduction It is becoming increasingly difficult for users to interact with the slew of portable gadgets they carry, especially in the area of text entry. Although miniature displays and keyboards make some portable devices, such as cell phones and PDAs, amazingly small, users’ hands do not shrink accordingly. To solve this problem, we proposed a […]

“A car that can track its own location and calculate the direction and distance needed to get to a final destination given by user inputs.” Elevator Pitch For our final project, we built a self-driving car that takes in inputs for a final destination and drives itself from its initial location to the final destination.

The Elevator Pitch We successfully implemented a prototype RFID checkout system that will enable consumers to instantly pay for their entire purchase upon arrival at the register, increasing customer satisfaction, reducing retailer costs, and ultimately lowering consumer prices. Summary Shopping in the present day usually involves waiting in line to get your items scanned for

This is my first time using the AVR. I like to learn using the ATTiny 2313, because it is faster than MCS-51, cheap and the circuit is very simple. The chip has only 20 pins. I was interested because I want to build a simple line follower robot controlled by this MCU. Board Construction The

Introduction We can use a PC for connecting the homemade data acquisition hardware and produce the GUI for user friendly graphical presentation easily. One of the project that uses Visual Basic is the Data Acquisition & Logging System using AT89C51 made by Abbas Raza. In this project we use a PC for GUI display and

INTRODUCTION AVR910 is a very useful programmer. It can program almost complete range of AVR chips. The original version made by Klaus is here, http://www.mikrocontroller-projekte.de/Mikrocontroller/AVR-Prog/AVR-Programmer.html. The programmer uses ISP capability of AVR chips. AVR910 first appeared in AVR910 application note by ATMEL. It is one of the fastest programmers for AVR. We can use AVR

Servo motors are so called “closed feedback” systems. This means that motor comes with control circuit, which senses if motor mechanism is in desired location and if not it continuously corrects an error until motor reaches proper point. Servo motors are widely used in robotics, remote controlled planes, vehicles. So they come in many shapes

Lets have some practice and write simple AVR LCD menu routine. For this we need to write LCD control library. I decided not to use one from AVRLIB. LCD controlling isn’t difficult just a few lines of code unless you want to make it more universal. I want to demonstrate how LCD menu control may
