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 …
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 …

Introduction Our project is an electronic voting system. The system allows for quick and accurate voting electronically. The system uses a client/server architecture, which allows voters to cast ballots on the client terminal. Each client interfaces with the server, which keeps track of the entire system. High Level Design Our design is broken up into …
Story What is a Bootloader? Microcontrollers require a programmer to install firmware on them. A programmer is a device, that when combined with software, loads firmware to the microcontroller. There are many programmers available. I won’t go into to detail about them, but I will say that if you intend to do more than just tinker with …
Introduction The Juicer is a wirelessly controlled, programmable juice maker which will mix each ingredient of a recipe to the exact proportions every time. The Juicer will take a recipe selection serially via either the keyboard or the wireless remote and dispense the juices into the cup below. Force and Photo sensors are incorporated to …
Things used in this project Hardware components: OLED 128×64 SPI-capable Available on Aliexpress or eBay for $4 to $20 × 1 For standard Arduino platforms, use the unmodified Adafruit libs Story I like cheap electronics for playing. Cheap is good for budget conscious hobbyists and China is delivering lots of toys for playing – one …
Overview The SmartBlinds system uses a microcontroller to control the angle of a set of miniblinds used at home, in the classroom, or on the job. Using SmartBlinds, a user can more effectively control the light coming into the room, or have an alarm that opens at a specified time. We’ve noticed that despite the …
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 …
Introduction: One Sentence Sound Byte: “Grillzilla – A wireless meat grilling thermometer which alerts the user whether their entrée is cooked according to USDA recommendations via LCD and voice feedback.” Summary of what we did: As the weather starts to get warmer a common type of social gathering that occurs is the barbeque. Barbeques are all about …
This tutorial is meant for beginners in the field of Atmel AVR programming. I hope that you already read my first tutorial Blinking LED using Atmega32 and Atmel Studio. In most of the embedded electronic projects you may want to use a push button switch to give user inputs to the microcontroller. To use a push …
