Fertilizer Feed Rate

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 …

SSD1306xLED Tinusaur ATtiny85 Library for SSD1306 1

SSD1306xLED Tinusaur ATtiny85 Library for SSD1306

Story SSD1306xLED is a C library for working with the SSD1306 display driver to control dot matrix OLED/PLED 128×64 displays. It is intended to be used with the Tinusaur board but should also work with any other board based on ATtiny85 or similar microcontroller. The 128×64 OLED is controlled by a SSD1306 circuit and could be interfaced over I²C. The code could be divided …

POV Cylinder

POV Cylinder with Arduino Due Using Atmega

Story Introduction This is my first Arduino project. My work was inspired by several maker projects that created Persistence of Vision Displays [2,3,4]. Persistence of vision (POV) refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films [1]. The …
