"pulling man" installation ( ball goes up and down based on servo time

Hi all,

Wondering if this i a good setup for 1 ball going up and down based on given time. I want servo in the For loops of the pattern to be rotating based on time in Milliseconds..not sure if its correct this way.

Als am jumping from each void to another one by just using an variable...is this correct of is there an much easier way to do.

kind regards,
ian

iejun:
Als am jumping from each void to another

The correct term is function. void is the return type, in this case indicating that the function doesn't return anything.

iejun:
am jumping from each void to another one by just using an variable...is this correct of is there an much easier way to do.

The concept is ok but pattern02() will never run because you don't call it and thus the code in the other two functions will only ever be run once.

It's not very clear to me what you're trying to do but the use of delay() is likely to cause you problems. You probably want to be constantly reading the sensor, not with multiple seconds of delay between readings. I suggest you study File > Examples > 02.Digital > BlinkWithoutDelay and the accompanying tutorial:
https://www.arduino.cc/en/Tutorial/BlinkWithoutDelay
To see how you can write your code without any use of delay().

aa thx for this
