Virtual Archery using ATmega1284P

Leave a Comment / Using Atmega / Tech Master

Introduction We decided to create a virtual archery game for our ECE 4760 final project. This game consists of an ATmega1284P microcontroller, a TV for display, and multiple pieces of hardware. All of these devices communicate together to simulate a three-round game of archery with a target that is 20 feet away from the user.

Working with TWI (I2C) sensors / Devices Using Atmega

Leave a Comment / Using Atmega / Tech Master

Introduction The I2C is a multimaster, multislave serial single-ended computer bus and was invented by Philips in 1982. The atmel microcontrollers use a compatible to I2C serial bus that is named TWI (Two Wire Interface). The TWI supports serial communication at 100 kHz and 400 kHz. The master and slave devices that are connected to TWI bus have a

LCD Scrolling Display Module Using Atmega

Leave a Comment / Using Atmega / Tech Master

A microcontroller is a device which has an inbuilt processor surrounded by few dedicated hardware modules. Once the microcontroller initializes them they start operating on their own. In case of an ADC it will do the sampling and digital to analog conversion all by itself and keep the converted data in its buffer so that
