Increase torque or reduce noise in DC brushed motors
By default, most Arduino pwm outputs are set to about 490Hz or 980Hz. These frequencies work quite well with small dc brushed motors but can cause unwanted noise or … Read more

quad encoder read speed

This is as much a programming problem as it is a mechanical issue I guess.
A few of us are working with quad encoders at the moment and I'm just wondering about ideas how to overcome a problem I've encountered using some.
I'm using interrupt on change to count encoder ticks and also reading a 16 bit timer for the interval between ticks on each motor.

Use an Arduino to get to the Moon

So, this whole Maker movement has got you excited, and the rocket you are building in your backyard is nearing completion.  But you haven't decided on a navigation computer yet.  You were thinking of using a laptop, but your daughter needs it for school.  Maybe a Beaglebone Black.  Darn!  Seems they are sold out everywhere.  You look around your lab, but all you can find is an Arduino. At first you pass right over it.  But when you can't find anything else, you start to wonder, "Could it get me to the moon?"
