In other words, easy to press, but not so much that it could be pressed just when trying to rotating it.<p>But I decided to try and measure it. I got a kitchen scale, and put the encoder on it (with the clear plastic knob) and zeroed out the scale. Then I slowly increased pressure on it till it clicked. Did it several times. Somewhere around 15-16 oz or 450-460 grams is when I felt the click.</p></p>

The waveforms show the rising edge as going from ON to OFF and the falling edge going from OFF to ON. That can't even be blamed on a bad Chinese to English translation. What were they thinking?</p>

Rotary encoders usually require a lot of pressure to perform the click, how about this one?</p>

Therefore, if it isn't specified, it is because they aren't incorporated in the device.<p>Luckily, the Arduino boards inherently limit the amount of current they can drive. However, you should still use current limiting resistors because you can still damage the product.</p><p><em>EDIT: Sorry, I didn't realize both posts were by the same user.</em></p></p>

Then it was dead...</p>

I read the datasheet (not the best I've seen) but found no reference to these resistors. From the example sketch, it seems the LEDs are hooked up directly to the Arduino pins. --Thanks--<p>As for the encoder, it works well...</p></p>
