Arduino GUI Part 5 Potentiometer

Part 5: More analog data is sent from the Arduino to the PC to display the voltage at the wiper of the potentiometer. The count data is converted to volts.

This is a series of six videos that covers the creation of a Windows application to control devices connected to an Arduino microprocessor. C# is used to develop serial communications between the PC and an Arduino. The C# windows form app is further developed to transmit both analog and digital data and commands in both directions between the Arduino and PC.

Very nice series. I'not familiar with C#. Are there a tool for plotting data in an X, Y-graph rather than in a status bar?

I am in part5 of your tutorial, but I am using different micro controller. My controller is 12 bits ADC and 3.3v, do I still have to declare numdata and volts as single variables or different type? when I declared them as single, my program gives error. Thank you for helping me, you are a great teacher.

Hi, sometimes i get problem with invoke method. Where could the problem be?

I can´t get a reading from the potenciometer. It shows a range from 0.00 to 0.07, regardless if the A0 is connected to the potenciometer or not. I check the wiring and everything is fine, then I change to A1 and the same thing happen. Also a double check the code and everything seems to be typed right. I am using a potenciometer of 10K, I dont know if that could be the problem or not. Any suggestions?

I have a problem with reading the potentiometer, when I move the potentiometer at first (Start Debugging) everything is fine, but after I pressing on the Butten Push
There is confusion in the display between the click counter and the potentiometer display.
If I exit from Debug and re-entry its solves the problem until PB is pressed again
can anyone help me ?

Does the Arduino IDE have to be running while the GUI is active? and to make the arduino run at all

Sir how to save reading in potentiometer in PC by this seriel terminal how thing add in this

Thanks for sharing!.
Unfortunately for me the programming on Winzoz won't be much of use since i use Only Linux.
