AVR/Arduino RFID Reader with UART Code in C using Atmega

Leave a Comment / Using Atmega / Tech Master

RFID is the craze, found everywhere – from inventory systems to badge ID systems. If you’ve ever been to a department store and walked through those metal-detector-looking things at the entrace/exit points, then you’ve seen RFID. There are several places to find good information on setting up RFID, and this instructable focuses on installing the Parallax RFID reader (Serial TTL)

Output number when button is pressed using Atmega16 microcontroller

Leave a Comment / Using Atmega / Tech Master

This is simple demo program of reading button state, lighting LEDs, sending information via USART. 8 buttons are connected to Atmega16 port A, 8 LEDs to port B via current limiting resistors. While none of buttons arent pressed there is running light on LEDs performed, but when any of buttons is pressed then LEDs display

Wii Conductor Using Atmega32

Leave a Comment / Using Atmega / Tech Master

Introduction Our project can be described as a simplified implementation of Wii-Music, utilizing a Nintendo Wii Remote (Wiimote) to play a gesture-based music game with the player as a virtual music conductor. We decided to do this project since it exploited two of the Wiimotes more peculiar features: its wand-like shape and the embedded 3-D

USB controlled DDS signal generator with ATmega88

Leave a Comment / Using Atmega / Tech Master

A simple signal generator which produces sine waves (or any waveform really) at audio frequencies using DDS and is controlled a USB serial connection. Only 2 chips are used in this circuit. The AVRATmega88 which produces the signal, and an FT232R for the USB interface. While a computer is required to control the varying frequency of

Speech Lock Using Atmega

Leave a Comment / Using Atmega / Tech Master

we designed and implemented a speaker recognition device that acts as a lock triggered by the sound of your voice saying a specific passcode. The implementation uses hardware filtering from a microphone and many signal processing concepts in software. All software and matching is implemented in the ATmega1284p. The lock has two modes: training and

Speech Synthesis on Atmega128

Leave a Comment / Using Atmega / Tech Master

I had this one project where the device was supposed to speak out the output. And I was too Lazy to actually go and build a PC based application and not that lazy to make it on a micro controller. So here is some of my research where i am gonna show you how to

The Breath-o-Matic Using Atmega32

Leave a Comment / Using Atmega / Tech Master

Introduction Let us introduce the Breath-o-Matic alcohol sensor. The Breath-o-Matic is an electronic, non-invasive method of measuring a human’s blood alcohol content (BAC). Its elegant, yet discombobulated design embodies a cheerful mix of mechanical and semiconductural components. Simply blowing into the mouthpiece causes the Breath-o-Matic to automatically begin taking a sample of your own foul

UV Sensor ML8511 AVR Atmega library

Leave a Comment / Using Atmega / Tech Master

Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm. The ML8511 is an ultraviolet sensor that output an analog signal correlated to the amount of UV light detected. By datasheet the sensor detects wavelength from 280nm to 560nm. Here I’ve implemented a driver for AVR Atmega, portable to other microcontrollers, that correlates the sensor output
