Fertilizer Feed Rate Controller Using Atmega

Abstract For a final project for EE 476 at Cornell University under the instruction of Bruce Land I designed and built a fertilizer flow rate control unit tailored to the needs of Lin Davidson. Instead of conventional mechanical drive methods, the delivery rate was controlled through the use of an Atmel AT90S8515 microcontroller. Ground speed of the tractor was sensed through the use of …

Self-Adjusting Window Shade Using Atmega644

Introduction The self adjusting window shade will automatically raise, lower, open, and close your blinds by itself. A computer terminal acts as a remote to broadcast instructions to the window shade via RF. These manual adjustments are stored into the microcontrollers system along with the rooms current ambient light and temperature settings. When these lighting …
