LOW COST-LOW SPEED OSCILLOSCOPE USING GRAPHICAL LCD AND ATMEGA128 MICROCONTROLLER

Low Cost, Audio Speed Digital Oscilloscope

The goal of the project was to design a low-cost digital oscilloscope targeted at students, hobbyists, and researchers. The requirements of the oscilloscope were three-fold: 1) cost less than $100, 2) capture frequencies over the range 20Hz–20kHz, and 3) constructable with a basic soldering iron and limited soldering skills. The primary parts of the oscilloscope are two Atmel ATmega644 microcon...

Onsite Data Acquisition Using Low Cost Open Source Microcontroller

Hand Gesture Recognition Using Ultrasonic Sensor and Atmega128 Microcontroller

The aim of this paper is to present a system that detects the hand gesture motions using the principle of Doppler Effect. Ultrasonic waves are transmitted by a sensor module and are reflected by a moving hand. The received waves are frequency shifted due to Doppler Effect. These frequency shifts in the ultrasonic waves are characterized to determine gestures. The gestures once recognized are ma...
