Hi all Arduinoers!
I am at my wits end with trying to solve a very basic Arduino2Max problem. I have a force sensitive resistor connected, via a breadboard, to an Arduino BT w/AT Mega 328. I had spent a lot of time just getting the program loaded onto the Arduino, but seem to have finally managed that now. Below is the programming code that I am using for this. All I would like to do is read data from Analog port 0, and have this displayed on the standard max patch.
Can anybody see where I am going wrong? I will included a picture of the breadboard set up (when I can figure out how), as I have tried a couple of arrangements taken from different sources and am unsure if it is correct. I am using a 10k ohm resistor. I also changed the last line of the programming code to Serial.write(32); as it Arduino could not understand 'BYTE', although I am not sure what the best value to put in here would be. The max patch has the serial reader linked to ARDUINOBT-Bluetoothseri and the correct port has been selected
Again, any help would be massively appreciated - I now have a splitting headache and need to suss this so that I can continue with my project. Sorry to trouble you with such a basic issue but I cant help feel that it's something really small that I keep overlooking.
Thanks in advance
