I worked to figure out the connection between the Arduino and Processing to no avail. I was able to create a force sensor circuit that changed the brightness of LED based on force.
I also revisited the Potentiometer.
I tried to combine the arduino and processing using the code from the tutorial video but the pot was not recognized.
Arduino code
/*
* Resistive Sensor InputResistive Sensor Input
* Takes the input from a resistive sensor, e.g., FSR or photocell
* Dims the LED accordingly, and sends the value (0-255) to the serial port
*/
int sensorPin = 0; // select the input pin for the sensor
int ledPin = 11; // select the output pin for the LED
int val = 0; // variable to store the value coming from the sensor
void setup() {
Serial.begin(9600);
}
void loop() {
val = analogRead(sensorPin); // read the value from the sensor, 0-1023
analogWrite(ledPin, val/4); // analogWrite (dimming the LED) can be between 0-255
Serial.println(val/4); // writing the value to the PC via serial connection
delay(50); // rest a little...
}
