Lab 3

This one was an exercise in using analog inputs, and ended up being a sort of squeeze meter. I used a Force Sensor Resistor at first to control the fading of a LED. With a series of "if" statements, I used values taken from the resistor to control a familiar-looking meter. Check out the videos, the meter's code is below. I think there's a more concise way to do it, but it works and was simple to quickly implement.

int potPin = 0; // Analog input pin that the potentiometer is attached to
int potValue = 0; // value read from the pot
int led = 11; // PWM pin that the LED is on. n.b. PWM 0 is on digital pin 9
int pin2 = 2; // high-low pins for the meter
int pin3 = 3; // high-low pins for the meter
int pin4 = 4; // high-low pins for the meter
int pin5 = 5; // high-low pins for the meter
int pin6 = 6; // high-low pins for the meter
int pin7 = 7; // high-low pins for the meter
int pin8 = 8; // high-low pins for the meter
int pin9 = 9; // high-low pins for the meter
int pin10 = 10; // high-low pins for the meter

void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
pinMode(pin2, OUTPUT);
pinMode(pin3, OUTPUT);
pinMode(pin4, OUTPUT);
pinMode(pin5, OUTPUT);
pinMode(pin6, OUTPUT);
pinMode(pin7, OUTPUT);
pinMode(pin8, OUTPUT);
pinMode(pin9, OUTPUT);
pinMode(pin10, OUTPUT);

}

void loop() {
potValue = analogRead(potPin); // read the pot value
analogWrite(led, potValue/4); // PWM the LED with the pot value (divided by 4 to fit in a byte)
Serial.println(potValue); // print the pot value back to the debugger pane
delay(10); // wait 10 milliseconds before the next loop
