Purpose:
Use a second button so one turns it on, and the other turns it off.
Equipment:
Push button
330 Ohm resistor
3 Led's (Any color)
Program Details:
Arduino
Time to Program and Complete:
10mins
Results:
No problems
Photo/Video Proof:
None right now
Program:
int led = 9; -This makes a variable called led which holds a value of 9
int onbutton = 3; -This makes a variable called onbutton which holds a value of 3
int offbutton = 2; -This makes a variable called offbutton which holds a value of 2
void setup () - void setup() is starting
{ - Start of void setup()
pinMode(led, OUTPUT); -Declares led (pin 9) to be an Output
pinMode(onbutton, INPUT); -Declares onbutton (pin 3) to be an input
pinMode(offbutton, INPUT); -Declares offbutton (pin 2) to be an input
} - End of void setup()
void loop () -void loop() is starting
{ -Start of void loop()
if (digitalRead(offbutton) == LOW)
{ -Start of if statement
digitalWrite(led, LOW);
} - End of if statement
else if (digitalRead (onbutton) == LOW)
{-Start of else statement
digitalWrite(led, HIGH);
}-End of else statement
}-End of program
