Hard Drive POV clock
- by SkinnyMAN
I am building a hard drive POV clock. (google it, they are pretty cool)
I am working on the code for it, right now all i want to do is get the hang of making it do simple patterns with the RGB leds. I am wondering if anyone has any ideas on how to do something simple like make a red line rotate around the platter.
right now what i have is an interrupt that triggers a function.
int gLED = 8; // pins for RGB led strip
int rLED = 9;
int bLED = 10;
attachInterrupt(0, ledPattern, FALLING);
void ledPattern(){
digitalWrite(gLED, HIGH); // This will make a stable image of slice of the
delayMicroseconds(500); // platter, but it does not move.
digitalWrite(gLED, LOW);
}
That is the main part of the code (obviously I cut some stuff out that arduino requires)
What I am trying to figure out is how can make that slice rotate around the platter.
Eventually I will make the pattern more interesting by adding in other colors.
Any Ideas?
