How to plot a real time bar graph on axes in Matlab GUI from the signal of Ultranonic Proximity sensor connected to A0 of Arduino?

The ultrasonic proximity sensor signal is connected to A0 of arduino. I want to plot a bar graph that will plot only the y-axis as the level of the tank on the axes in Matlab GUI. Please help me.

Hi Yooichi,

There are multiple ways to achieve this :

1. Using MATLAB Support Package for Arduino Hardware

MATLAB IO provides a way to establish a server-client connection between Arduino and host machine to send/receive data. The received data can be visualized using plot functions in MATLAB as mentioned in this link.

2. Using Simulink Support Package for Arduino Hardware

Using External mode communication between host machine and Arduino, the data read from the sensor can be visualized using a Scope block in Simulink.
