SerialCallResponseASCII - Send multiple variables using a call-and-response (handshaking) method, and ASCII-encode the values before sending. SerialEvent - Demonstrates the use of SerialEvent. VirtualColorMixer - Send multiple variables from Arduino to your computer and read them in Processing or Max/MSP. Whether its a singular wave or a multiple plot graph the Serial Plotter auto-resizes itself and color codes each wave. In-order to test the Data Visualization function you can follow the following steps: Connect a couple of sensors to your Arduino; Print the values of the sensors & Upload the code. Open the Serial Plotter. An Arduino library for easy graphing on host computer via serial communication arduino-library arduino graph plot plotter serial 94 commits.
Now that you have installed the latest version of the Arduino IDE(1.6.7 or above) its time to understand how the Serial Plotter actually works. The Arduino Serial Plotter takes incoming serial data values over the USB connection and is able to graph the data along the X/Y axis, beyond just seeing numbers being spit out on to the Serial Monitor. The vertical Y-axis auto adjusts itself as the value of the output increases or decreases, and the X-axis is a fixed 500 point axis with each tick of the axis equal to an executed Serial.println() command. In other words the plot is updated along the X-axis every time the Serial.println() is updated with a new value.
Remember to set the Baud Rate of the Serial Plotter so that it matches that of the code.
Multiple Plots
When displaying multiple waveforms, every separate variable/value/parameter is displayed using a different colour like shown below.
Arduino Plotter Tutorial
Inorder to plot multiple variables or waveforms simultaneously a 'space' is printed between the two print statements.

VLC Media Player (64-bit) has consistently been one of the most popular video players for years, and that isn't changing anytime soon. It even lets you create playlists on the fly and edit them from inside the app. Vlc free download for windows 10. It gives users more flexibility and format support than most other players and stays on the cutting edge in terms of features. VLC Media Player (64-bit) lets you add audio and video effects as you're watching a video for extra fun - and supports more playlist formats for easy, hands-free viewing. The app supports extensions and add-ons from all over the Web if you can find them.The standard version of the program covers most of the bases you need, though.
In this case the values of the variables 'temperature & humidity will have separate waveforms plotted on the same graph simultaneously.
