A Superhet/Direct Conversion AM receiver for 181.818 kHz using Attiny2313

Leave a Comment / Using Atmega / Tech Master

Downloads Download the AVRStudio assembly source vlflo13041105A.asm (html format) Download the AVRStudio Hex file vlflo13041105A.hex (html format) Photo of completed receiver. Its pocket sized, but not intended to be used that way because the antenna is a highly directional ferrite loopstick. Its only a matter of luck that there was room for all the components on the board, which […]

Embedded Foot Pronation Detection Using Atmega644

Leave a Comment / Using Atmega / Tech Master

Introduction and Rationale Our ECE 4760 design project integrates three different kinds of sensor measurements to track a users movement speed, regularity of gait, force on impact, pronation of foot, as well as other information that may be useful to a podiatrist. We believe there is a need for a cheap metering tool that can

Interfacing DC Motor with AVR Microcontroller Atmega16

Leave a Comment / Using Atmega / Tech Master

DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead let’s know more about
