The LED Hat is currently in countdown mode. Please wait until the timer expires.
Enter formulas using reverse Polish notation for each color channel (Red, Green, Blue).
cos(x),
sin(x), tan(x)
acos(x),
asin(x),
atan(x)
sqrt(x),
exp(x), abs(x)
pow(x, y)x: Position around hat (-1
to 1, 0 is front)
y: Height (0 to 1, bottom
to top)
t: Time in seconds since
start
t x + sin equals
sin(t + x)
This creates a moving sine wave around the hat.
