CrossRoads:
Please explain the idea behind changing the pin modes?
The design I proposed had the cathodes being driven high to disable the LEDs. If you change the pin to an input and let if float, the voltage becomes some unknown on the cathode, and +5 on the anode, so if you have efficient LEDs they could appear somewhat on.
I'm setting the pins to INPUT to disable them. But you are probably right, thats not grounding them and some voltage might be leaking out.
However I can't seem to figure out your method =/
How would you program the lightup() function?
I tried setting everything to OUTPUT and LOW but that just makes every LED light up for some reason. And still some are brighter than others.
This is what i have atm and need to re-program
void lightup(int led, char lens){
static int last = 0;
switch(lens){
case 'r':
//turn the last one off
pinMode(leftLensA[last], OUTPUT);
digitalWrite(leftLensA[last], LOW);
pinMode(leftLensC[last], OUTPUT);
digitalWrite(leftLensC[last], LOW);
//turn on given LED position
pinMode(leftLensA[led], OUTPUT);
digitalWrite(leftLensA[led], HIGH);
pinMode(leftLensC[led], OUTPUT);
digitalWrite(leftLensC[led], LOW);
last = led;
break;
case 'l':
//turn the last one off
pinMode(rightLensA[last], OUTPUT);
digitalWrite(rightLensA[last], LOW);
pinMode(rightLensC[last], OUTPUT);
digitalWrite(rightLensC[last], LOW);
//turn on given LED position
pinMode(rightLensA[led], OUTPUT);
digitalWrite(rightLensA[led], HIGH);
pinMode(rightLensC[led], OUTPUT);
digitalWrite(rightLensC[led], LOW);
last = led;
break;
}
}
On another note, still trying to figure out how to delay some instructions so i can actually animate the LED's.
