Vehicle Performance Meter Using Atmel Mega32

Leave a Comment / Using Atmega / Tech Master

INTRODUCTION The DomMeter is a car performance meter that measures acceleration to compute values important to car enthusiasts. Specifically, the DomMeter calculates the 0-60mph time, 0-30mph time, 0-100mph time, quater mile, eighth mile time and braking time, the max acceleration during that interval, distance travelled in feet and max horse power generated (after drag, roll losses and drive train

Thermistor Respiratory Monitor Using Atmega1284

Leave a Comment / Using Atmega / Tech Master

Our final project for ECE 4760 is a respiratory monitor that was designed for low-resource environments. The device calculates a patient’s breathing rate by detecting changes in temperature when the patient breathes through a mask. Features of the device include an alarm through a piezoelectric speaker which goes off when the patient stops breathing, and
