All we need to do is connect the signal to be examined to the specified Analog pin of the Arduino. The schematic for the Arduino Oscilloscope is simple. Python Libraries: Pyserial, Matplotlib, Drawnow.Arduino Uno (Any of the other boards can be used).The following components are required to build this project After conversion, the value per time is sent via UART from the Arduino to the PC where the plotter software which will be developed using python will convert the incoming stream of data to a waveform by plotting each data against time. For the conversion, we will be leveraging on the ADC (Analog to Digital converter) on the atmega328p microcontroller used by the Arduino to convert the Analog data at the signal input to a digital signal.

To achieve this, we need to first convert the signal from analog to digital and then plot the data. Oscilloscopes generally involve the visual representation of an analog signal applied to its input channel.

Today I will be demonstrating how to use the Arduino and a software, which will be developed with my favourite programming language Python, to build a low cost, 4-channel Arduino oscilloscope capable of performing the tasks for which some of the cheap oscilloscope are deployed like the display of waveforms and determination of voltage levels for signals. The only issue is they can be very expensive, Oscilloscopes that performs the most basic of functions with the least accuracy can be as expensive as $45 to $100 while the more advanced and efficient have cost over a $150. These reasons make the oscilloscope a must have tool for any engineer. It is also used by embedded software developers for code debugging and technicians for troubleshooting electronic devices during repair. It is primarily used for viewing waveform and determining voltage levels, frequency, noise and other parameters of signals applied at its input that might change over time.

The Oscilloscope is one of the most important tools you will find on the workbench of any electronics engineer or maker.
