Lab - Potentiometers

Here's the code i made/adapted, after soldering the pots, and connecting to analog.

 

 

/*
 * one pot dims, the other pot changes the blinking rate
 * modification of the following
 * http://www.arduino.cc/en/Tutorial/AnalogInput
 */
int pot1Pin = 0;   // select the input pin for the potentiometer 1
int pot2Pin = 1;   // select the input pin for the potentiometer 2
int pot3Pin = 2;   // select the input pin for the potentiometer 2
 
int pot1Val = 0;   // variable to store the value coming from pot 1
int pot2Val = 0;   // variable to store the value coming from pot 2 
int pot3Val = 0;   // variable to store the value coming from pot 2 
 
int led1Pin = 9;   // select the pin for the LED 1
int led2Pin = 11;  // select the pin for the LED 2
int led3Pin = 10;  // select the pin for the LED 3
 
void setup() {
   pinMode(led1Pin, OUTPUT);  // declare the led1Pin as an OUTPUT
   pinMode(led2Pin, OUTPUT);  // declare the led2Pin as an OUTPUT
   pinMode(led3Pin, OUTPUT);  // declare the led2Pin as an OUTPUT
}
void loop() {
   pot1Val = analogRead(pot1Pin);   // read the value from pot 1, between 0 - 1024, for dimming
   pot2Val = analogRead(pot2Pin);   // read the value from pot 2, between 0 - 1024, for blinking
   pot3Val = analogRead(pot3Pin);   // read the value from pot 3, between 0 - 1024, for SOMETHING?
   
   analogWrite(led2Pin, pot1Val/4); // dim LED to value from pot1
   delay(pot2Val);                  // stop the program for some time, meaning, LED is on for this time
   analogWrite(led2Pin, 0);         // dim LED to completely dark (zero) 
   delay(pot2Val);                  // stop the program for some time, meaning, LED is OFF for this time
}
