In Week 2 we experimented with Arduino by triggering LED light with a button. We used a breadboard to attach the button, resistor, and LED to the Arduino and used a modified program from the Button Example.
The following is modified Arduino code:
/*
* Button
* by DojoDave <http://www.0j0.org>
*
* Turns on and off a light emitting diode(LED) connected to digital
* pin 13, when pressing a pushbutton attached to pin 7.
*
* http://www.arduino.cc/en/Tutorial/Button
*/
int ledPin = 13; // choose the pin for the LED
int inputPin = 2; // choose the input pin (for a pushbutton)
int val = 0; // variable for reading the pin status
void setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(inputPin, INPUT); // declare pushbutton as input
}
void loop(){
val = digitalRead(inputPin); // read input value
if (val == HIGH) { // check if the input is HIGH
digitalWrite(ledPin, LOW); // turn LED OFF
delay(random(500));
digitalWrite(ledPin, HIGH); // turn LED OFF
delay(random(500));
} else {
digitalWrite(ledPin, HIGH); // turn LED ON
}
}
We also formed our team which include the following members:
