Questions about Blink, Servo Noise, and Offsets

Hexy Questions, Problems and Suggestions
#1

I purchased my Hexy yesterday, and finally have him up and running.

I just have a couple of quick questions -

During construction, I noticed that I didn’t get a dim, red, pulsing light when I would power up the servos. Is this a problem? The board only displayed a steady green light, and the servos would whirl when plugged into slot 0, 1, 2, or 3.

I tried to upload the Blink sketch in the Arduino program to the board. It seems to upload, but I’m not seeing the blinking light. Is the Blink sketch supposed to work on the Servotor32 board? If it is, any idea why it’s not working on mine?

After the robot completes a move, I can hear that some of the servos continue making a sound. Is that normal?

Finally, I’ve been working on setting up the offsets. Is there a maximum offset, that, if exceeded, indicates that it would be better to just try reinstalling the servo?

Nope, just means it skipped the bootloader. I think it does then when its powered off the not-USB. As long as the servos are moving, it should be fine.

Blink is designed for the official Arduino boards, and so runs on pin 13. If you run it on pin 7, it should work with the red led you mentioned above.

Yup, that’s the servos holding their position.

If you start reaching 200, think twice about repositioning.

Thank you very much!
