by receiving IR rays from a reflecting spot on the shaft of the motor. The speed of the motor is controlled by PWM from the microcontroller. The project uses a microcontroller and a pair of sensors (Transmitter and receiver) which gives the output to the microcontroller. The timer and the counter of the microcontroller gives the speed of the rotating shaft. The microcontroller is interfaced with an LCD to display the speed. The LCD directly displays the speed of the device in rpm. The controller is

“align robot on center of the line algorithm”. Actually you does not need a microcontroller for implementing such a simple robot. A set of comparators and a motor driver circuit will happily do the job. But I am using the microcontroller just to demonstrate the technology. Also this project serves as a platform for advanced line follower robots which works on complex algorithms. AT89S52 from Atmel is the microcontroller used here. Sensor. The sensor part consists of a set of LED / LDR pairs

This leg behaves similar to a normal human leg and it can perform operation like walking‚ running‚ climbing stairs etc. The entire system is controlled with the help of advanced microcontrollers and digital signal processors. The signals are taken out from the human brain with the help of electroencephalography technique. The person can perform operations like walking‚ running etc just by their thought. This system will be very much

Chapter I INTRODUCTION A clothesline or washing line is a piece of rope or wire that people use to hang wet clothes to dry. [Merriam Webster] It may any type of rope‚ string‚ cord‚ or twine that has been stretched between two points generally outside‚ above the level of the ground. Clothing that have been washed is hung along the line to dry‚ using clothes pegs or clothespins. Washing lines are attached either from a post or a wall‚ and are frequently located in back gardens‚ or on balconies. Longer

High-level Design: This project used an Atmega644 microcontroller clocked at 20MHz in each of the two functional modules for processing. Memory storage is provided by a standard Secure Digital (SD) card. Xbee modules provide bidirectional wireless communication and we use the TLV5616 DAC chip for generating analog audio. The LM358 dual op amp provides active filtering to the output of the DAC. Music files can be added to the SD card using any computer with a multimedia card reader. Once the
