Portable Digital Oscilloscope using Arduino

Abstract

Electrical signals can be graphically shown on an oscilloscope to show how they change over time. It is a fundamental instrument for determining electrical parameters such peak voltage, frequency, duty cycle, pulse width, and examining various waveforms. Currently available digital oscilloscopes are quite pricey, bulky, and difficult to transport. The portable digital oscilloscope powered by the Atmega328p can be very helpful in overcoming these drawbacks. The advantages of a portable digital oscilloscope employing an Atmega328p are low cost, portability, light weight, low power consumption, ease of use, and others. The Atmega328p IC, an Organic Light Emitting Diodes (OLED) display, a breadboard, tactile switches, resistors, capacitors, diodes, and jumper wires are the components utilized. The importance of this research study comes from its ability to demonstrate that oscilloscopes based on the Atmega328p can be just as helpful as conventional oscilloscopes. The system will be able to function like a standard oscilloscope, which makes it useful in electronics labs and as a standalone instrument. The challenges faced by the conventional oscilloscope is that the oscilloscope cannot be carried out of the laboratories and for the oscilloscope to buy is not economical, that's where the oscilloscope using Arduino comes into the picture. The objective of the digital oscilloscope using Arduino is to make it useful for analyzing almost all types of waveforms with AC or DC supply.
