Introduction: Make PCB Pattern of LEDs Arranged in a Circle
Coordinates (x, y) of LEDs and resisters position are obtained by
x = r sin( s ) + a
y = r cos( s ) + b
where x, y are the coordinates of the points on the circle,
r is the radius of the circle,
s is the angle
and a, b are the coordinates of the center of the circle.
On LibreOffice calc, they are
in the cells.
The positions of LEDs, Resisters(Pattern1) and Resisters(Pattern2) are shown in the graph draw by calc.
Set obtained coordinates in KiCad.
Set rotation value in KiCad.
Then you can get LEDs and resisters PCB pattern.
We have a be nice policy.
Please be positive and constructive.
