กวาดจาก 0 ถึง 180

A sweep moves the servo smoothly across its whole range instead of jumping. It's the classic way to see your servo come alive. 🌊

The trick is to step the angle one degree at a time. Each tiny write() nudges the arm a little, and together they look like one smooth motion.

A for loop is perfect here. Count from 0 up to 180 and write each value as you go.

Without a pause the loop finishes before the arm can move. A short delay() lets each step physically happen.

The delay value controls sweep speed. A bigger number makes a slow, graceful sweep; a smaller one makes it whip across quickly.

To sweep back, run a second loop that counts down from 180 to 0. Together the two loops make a full there-and-back motion.

Drop both for loops inside loop() and the servo sweeps back and forth forever, just like the Arduino Sweep example.

Stay within 0 to 180. Pushing a standard servo past its stops makes it buzz and strain, which wears out the gears.

Want a faster sweep without a tiny delay? Increase the step size by counting up by 5 instead of 1.

Before doing real work, many projects center the servo at 90 degrees first. It's a tidy, known starting position.

Sweeping is gentle on the gears, but sometimes you want a fast snap to a target. Pick smooth or snappy based on your project's feel.

Let's see why a sweep needs a pause between steps.

Step the angle in a for loop with a small delay, then loop back down. That up-and-down pattern is the full servo sweep. 🔁
