Those buck converters will change the output voltage to make the feedback pin, connected to the output via a voltage divider, become 1.25V or so. If feedback is higher, output gets lower and vice versa. If one changes the ratio of resistors in voltage divider, output voltage will change. This is usually done by turning […]

Summary This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16×2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being

Introduction Quite possibly the slowest and lowest resolution of any scanner on the market today, but it sure is mesmerizing to watch.. and it actually works! That’s about the best way to describe this behemoth of a project, which involved countless hours of building, gluing and scavenging for parts. The goal we strived for

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

MP3 is presently a household term; the reader will likely own a few, barring any intervention from the RIAA. Since it’s not always practical to sit in front of a monitor and keyboard when you want to listen to music (e.g. in a car, on the couch, in the bathroom), we decided to create a

1. Introduction For our final project we built an ATmega32 based stepper motor controller which measures the angular position of the motor shaft using an optical encoder and quadrature decoder. Our system performs 3 basic functions: (1) Communicate with a PC by means of a RS-485 interface, and (2) Generates step and direction signals for

We have designed a programmable infrared receiver which can utilize any pulse coded IR signal to play Connect Four from a remote distance. The programmable infrared receiver device we have created can decode any pulse-width modulated signal of an IR remote control, store it in non-volatile memory, and then recognize that signal again the next
