Hi, thanks for the help, Im still having problems
When I use your code i get a cant convert float to int
so I tried after converting value from LDR, float angle = 180 - (LDR / 5.68333);
float x = 90 + 65 * cos(angle);
float y = 490 + 65 * sin(angle);
Now I got a perfect line from midpoint of arc to edge of arc, but the angle in the debug output: example 156.732 doesnt match where the needle in the meter is, the needle is shifting all the time even though the LDR is giving a constant value?
