Hello, I have successfully drafted the Ardunio code for capacitive sensing. The serial Monitor shows right values. Also, I have successful drafted the processing code which shows the exact same values from Arduino’s serial monitor on processing’s console. However, on processing the drawing funct…

Hello, Welcome to the community! Try this for Arduino code for testing: boolean toggle = false; void setup() { Serial.begin(9600); } void loop() { long total1 = 271828182; long total2 = 314159265; if (toggle) { Serial.print(0)…

Hi, Thank you so much for suggesting. I understand you are saying that I’m sending string to processing rather than integers that’s processing is unable to read numbers? Where in my code within processing, I shall put your modified code?

I’m new to this. Could you please put changes into my processing code and share it as a whole so i could test it please

[image] SusanAlyse001: Could you please put changes into my processing code and share it as a whole so i could test it please You can try the suggestions I made: Receive as a String and print as a String for testing When you want to use the received data as a number you have to convert; see…

Hi, sure. So I understand that my current code is sending a string to processing and you want me to test string data. Which part of my processing code should i remove so my string doesnt convert into integer?

You are receiving Strings in the array; that is fine and works. It is much more complicated to send “numbers” with Serial.write() (only sends a byte) and I would not do this. You must convert the string you received (Strings are in array) to numbers if you want to use them as numbers. I provided …

Sure. So I get these points. Please correct if I m wrong: My arduino is sending string data My processing is converting string into integer You are suggesting that i should not do the second step and receive string on processing as well? Is this correct

You are sending a long data type as a String with Serial.print() You are receiving a String and converting it to an int in your code. Consider saving String in array initially until you get this working and then convert the String to a long data type when it is required. Breaking into steps is eas…

Thank you. So now I’m sending “int” instead of string through Arduino and processing is receiving int without any conversion. But same issue, drawing function now working Arduino: #include <CapacitiveSensor.h> /* * CapitiveSense Library Demo Sketch * Paul Badger 2008 * Uses a high value resis…
