I got a little problem with my rotary encoder.
Hooked it up to my arduino (pin 3/5) like this: (see pic)
I am using the standard arduino node to read it, but this is what happens.
when I turn the button, both pins 3and 5 go from high to low and back. thats weird because what is supposed to happen is that just one of the pins should go up or down right? or is that not how it should work?
somebody got some experience with this? please help me out!
thanks anton for your info, so I discovered that I wired the encoder the right way.
I still have some troubles with processing the input in vvvv. is there anyone who has a patch that works with gray code? I connected the input from the sensor to the counter node but that obviously does not work properly.
the problem is not only the processing of the data in vvvv. these rotary encoders have one problem: if you can’t process their data fast enough, rotation information will get lost. and most likely processing the direct (on/off) data in vvvv is too slow. I recomend using a Phidget Rotary encoder:
like this one here: http://www.robotshop.com/en/phidgets-usb-rotary-encoder.html
The Rotary addition is done on the hardware and then a count-information is processed to vvvv. It’s realy simple to use.
If you still want to use Arduino, do the addition-logic directly on the arduino and then send the value to vvvv. but you can’t use Firmata then.
you could process the data directly in arduino which is fast enough. phidedts are easy to use but last time i used in in a projecr ihad the problem that i had to reset its value external from vvvv which introduced a somehow inaccuarete resetvalue when moving the encoder fast over the reset switch. i guess doing that reset to default directly on arduino would help on that.
