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

Sanchit Sachdeva, Ramandeep Singh

Abstract: In this paper , we have discussed the development of existing digital oscilloscope which is used for research and development purpose, instead of using cathode ray oscilloscope we have realized a circuit using ATmega128 IC [1]. To convert costly device affordable and which consume less space and less power leads to save time and money. In this way we have try to overcome the cost and space occupied by oscilloscope.

Keywords: Oscilloscope, Graphical LCD, AVR Microcontroller, LM358 Comparator, cost effective, compact size, embedded system, research and development.
