Square and triangular output waveforms of 525Hz and 530Hz captured on the screen during testing are shown in Figs 4 and 5, respectively.

The software must plot its output waveform on your PC. 3: Message after the hardware successfully connects to the PCįeed any squarewave input of up to 5kHz at CON1. When the board gets connected to your PC, you will get a confirmation message for three seconds as shown in Fig.

2: Message on the screen when the PC-based scope is run for the first time TestingĪfter installing the PC scope application, click ‘Connect’ button on your PC screen to connect to the Arduino board (Fig. The Y-axis range is set using the voltage selection control. The display points along X-axis are calculated based on the user-defined time scale.

The serial port data is captured through Arduino at regular time intervals and plotted as a graph on the screen using the Plot function library.
As stated earlier, the front-end PC software for signal acquisition and processing is developed using NI LabWindows. With this, you get ADC conversion every 20µs, which is much faster than the UART data transfer rate.

So here the ADC is configured with additional lines of code to get samples faster than 85µs by setting the prescaler to 16. At this speed, bytes of the input are pushed at time intervals of around 85µs.īy default, the ADC configuration of the Arduino gives samples every 116µs. The sketch reads pin A0 of Board1 and sends to UART at 115200 baud rate. It is important to get the ADC signals much before this time to get reliable data plotting. Baud rate of 115000 gives time interval of around 85 µs. The sampling rate of this PC scope application is limited by the rate at which the data is sent to the PC. Additional voltage dividers can be used in case you need to measure voltages higher than 5V. It will work as a current limiter in case the input goes beyond 5V. Connect a 10-kilo-ohm resistor in series with the input. A low-power, fast-switching diode like 1N4148 can be used to protect the input pin. So it is advisable to add a small protection circuit to limit the input voltage to 5V and clamp the negative voltage. The ADC of Arduino can measure voltages up to 5V. 1: Circuit of the PC-based oscilloscope using Arduino Connect the Arduino board to the PC and flash the sketch into the microcontroller on the Arduino board. Next, open the Arduino sketch from Arduino IDE and compile the sketch.

Install PCScope.exe program (developed by author) in your Windows PC and open the application. You need Arduino sketch (pcscope.ino) and PC software or executable file (PCScope.exe) in order to use this circuit. Connect switching diodes (D1 and D2) as input protection circuit to pin A0 of the Arduino’s ADC. Any external power supply for the board is not required as the board is powered by the USB only. The Arduino board connects to your laptop or PC via the USB cable. The PC scope set-up is quite simple and straightforward as shown in Fig. This gives an effective sampling rate of 12kSa/s. The Arduino sketch is coded to read the ADC using ISR, and the UART baud rate is configured at 115200, which sends data at 85µs intervals. The sampling speed of the oscilloscope is limited by the baud rate of the UART. A Windows-based application developed using NI LabWindows opens up the virtual COM port and starts plotting signals visually using Graph libraries. A virtual COM port is created by Windows whenever the Arduino connects to the PC. The captured input signal is fed to UART via UART-USB converter in the Arduino to the PC. In the project, we use pin A0 to capture the input signal. The AVR microcontroller has an inbuilt ADC. For this project, you can use any variant of the Arduino as hardware. The Arduino board consists of Atmel’s AVR microcontroller, which can be 8-, 16- or 32-bit based on the type of the board. This application works as the front-end to plot input signals as waveforms on your computer screen.
You also need to install an executable file or application in your Windows PC. We have provided here an Arduino sketch, which you can compile and load directly to the Arduino.
The Arduino board, the heart of the oscilloscope, reads the values from its inbuilt analogue-to-digital converter (ADC) and pushes these to the PC via USB port.
You can use this oscilloscope to capture frequency signals up to 5kHz. Here we describe how you can make your own oscilloscope at a very low cost using your PC and an Arduino board as the hardware for signal acquisition. PC based Oscilloscope score over standalone oscilloscopes due to their compact size, low cost and ability to do offline analysis. Oscilloscopes are an essential tool for electronics hobbyists and professionals to verify that their designs would work as expected.
