Step 1: The Beginning Last week I decided to make a classic Arduino clone with an ATMEGA328P-PU. I seemed to be so easy and quick but a very bad surprise for me: I odered the cheaper ATMEGA328-PU (non P!!) that is to say: non pico power. The difference: this IC needs a bit more energy […]
Introduction The following diagram shows the system schematic of the Smart Plant Feeder. It contains the several major blocks: ATmega 323 is the CPU of the system. 5 VDC power supplier: an adaptor first transforms 110 VAC 60 Hz into 9 VDC; then a regulator keeps VCC stable at 5 VDC. A crystal of 32KHz
Board Design For part of my final project I want to make my own USB audio recording device. So I’ll try to develop all the necessary electronics this week. I have the analog circuitry I need from inputs week. But I don’t have a board ready to go with a USB-capable microcontroller (bit-banging will not suffice,
This tutorial series designed specifically for beginners. If you are a beginner looking to play with cool electronic stuff, then you are going to find this very useful. This AVR tutorial for beginners series is going to cover all the information about microcontrollers. I will also focus on projects and together, we will make various
Introduction One of the more challenging aspects of owning a home entertainment system is dealing with all the remote controls. My device is designed to tackle this problem. Specifically, the universal remote control I implemented is able to learn the signals used by other remote controls, store those signals in its own memory, and send
Introduction Most homes across the world lack a security system of any sort. The goal of our project was to design a simple security system using the Atmel AVR ATmega1284p microcontroller that most people could build without too much hassle for an affordable price. This project uses a few external peripherals to accomplish this goal;
Introduction Several different approaches have been explored in developing a system to track eye movements. These approaches span from measuring reflections of infrared light to using advanced imaging techniques to monitor specific features within the eye. While a variety of reports exist on measuring infrared reflections off of the eye, the long term effects of
Introduction We designed and built a glove to be worn on the right hand that uses a Machine Learning (ML) algorithm to translate sign language into spoken English. Every person’s hand is a unique size and shape, and we aimed to create a device that could provide reliable translations regardless of those differences. Our device
Introduction What is seeing without feeling? The field of Virtual Reality has recently been gaining much attention, with the Oculus Rift and Google Cardboard paving the path of visualizing a world that is not physically there. But what if the virtual reality experience could be enhanced by incorporating tactile sensing? The Haptic Glove we developed
INTRODUCTION In the modern American classic, Rocky IV, Ivan Drago (portrayed by Dolph Lundgren) is shown utilizing a then-futuristic electronic punch meter (in addition to anabolic steroids) in his quest to triumph over Rocky in one of the Cold War’s only face to face confrontations. While we dispensed with the communist symbolism (and controlled substances)
