Every Product Showcase should be done like this.

This is the best Sparkfun video I've seen. I really useful introduction for people new to stepper, servo and controlled DC motors.

[TT1TTOne]

When would you have a use of the 2 other cables on 6-wired stepper motors?

[Lokivoid]

You can always add a shaftmounted encoder to a stepper, and solve that whole "no feedback" problem.

Great post. New stuff is always interesting but I learned so much more in this video. Thanks for being longer and more detailed.

[DanFrederiksen]

it's ounce inch, not ounce per inch. and it should be metric. not archaic units.

you may also want to carry real servo motors which is what is used for serious stuff. RC servos are not really precision

@iHeartMagic Usually quadrature encoders are used, which have two optical sensors at different locations. What this means is that when it turns in direction 1 it will output 00, 01, 11, 10, 00, ... while in direction 2 it will output 00, 10, 11, 01, 00, ...

@GENERALCHAOS13 BLANK** typo XD see 

[GENERALCHAOS13]

hey i went bank i cant think what ic chip i can use for lpc1114 to control a 12 led  pin 1 vin pin 5 ground (well 2 ground pin is grounded to 3 leds and 3pin grounded to 2 led ) im split them so i can control singly so il have 12 leds to control

[GENERALCHAOS13]

AWW i wanted to pet a baby cow XD but good vid

[iHeartMagic]

how does the optical encoder tell if you're going backwards instead of forward. meaning if you're spinning one way but then change to go the opposite. ever since I've taken apart an old ball mouse I've wondered about this. high fives for anyone who answers.
