001g_Stop_LED_Game
Project Overview:
-Create a game that can stop an LED with the push of a button. Increase the speed and award points to the user.
Code:
int led3 = 3; // the number of the LED pin
int led4 = 4; // the number of the LED pin
int led5 = 5; // the number of the LED pin
int ledGreen = 6; // the number of the LED pin
int led7 = 7; // the number of the LED pin
int led8 = 8; // the number of the LED pin
int led9 = 9; // the number of the LED pin
int btn = 2;
boolean Direction = true;
int score = 0;
int highscore = 0;
long previousOnTime = 0;
long previousOffTime = 0;
int ArrayofLeds[7] = {led3, led4, led5, ledGreen, led7, led8, led9};
void IsGreen();
void NotGreen();
void BlinkLedOn(int);
void BlinkLedOff(int);

What I learned / Problems
What I learned:
- I learned how to use the mills() function to track the time on the Arduino. This was used to replace the delay in the code to make the LEDs blink back and forth.
Problems:
- I found it difficult to make the LEDs blink back and forth without the delay function.
