If you have an Arduino circuit or any device that sends serial data via bluetooth, usb-otg or wifi and you want to reward it in real time as well as save it in excel format, use this app.

* graph up to 5 data in real time
* automatic stop after "n" data.
* customizable graphics color name variables etc.
* the Windows version is totally free (link to the repo on github below)
* Settings are automatically saved for later use.
* connection via USB-OTG (only for Arduino uno, Mega, nano, CP210x, CH340x, PL2303, FTDI)
* WIFI option included for esp8266
* Includes Manual and sample code for Arduino.

The circuit that sends the data must send only numeric data (never letters) separated under the following format:
"E0 E1 E2 E3 E4" each data must be separated by a space and at the end there must also be a space. You can send one data, two, three, maximum must be 5, each data must have a space at the end even if it is only one data. the delay () time in Arduino must be exactly the same as the one you use in the app.

if you use Arduino download the example sketch.
here you can find the MANUAL AND test code for Arduino:
