I want to edit this code from a sunlight tracker, i want to edit it so the horizontal motor can rotate 360° aroud insted of 180 (i would be changing the servo for a continues rotation servo) and as u can see the code has 2 servos and 4 ldr censor, i woikd like to eliminate the vertical servo from the code i only need the horizontal servo but i need it to move in any direction as 360 around as need to poit at the sun as if i was in a moving car that changing direction but the tracker wold always point at the sun

Hey there,

Three questions:

1. Are you aware this forum is for Particle, not really arduino?
2. What code?
3. What’s your question?

I believe you really do need two servos to capture the whole range of motion of the sun ~~, unless you happen to live on the equator.~~ Why do you think one would suffice?

Horizon and “sun’s zenith” (elevation at noon) don’t really share one plane anywhere on earth - especially not at the equator 😉

On the other hand, near the poles you get minimum elevation of the sun in the course of a day, but driving around by car isn’t much fun there either 🕶
