Re: help with Lsmds1 9 dof board

in short this is my attempt to get degres or roll and pitch

heading *= 180 / PI;
valH =map (heading, -180.0 , 200.0, 0, 360);


pitch *= 180 / PI;
valP =map (pitch, -200.0 , 200.0, 0, 360);

roll *= 180 / PI;
valR =map (roll, -200.0 , 200.0, 0, 360);

Re: Piezo Vibration Sensor and arduino Help

thank you
that seems to some how work
Lowering the values to 10 = no serial print
lowering to 20 = get some feed in serial print
lowering to 30 = no serial print.

what values do you recomend for this.


I am using the default knock form arduino software

thank you

Re: Lilypad + Piezo Vibration Sensor Enquiry (HELP)

first: have you set up the piezo , so arduino can read from it. ( if so. post pics of your setup) second. to direct data to software from arduino, there are several ways to do it. from max/msp , Pd, processing. etc. etc. for flash use this add on. http://protolab.pbworks.com/TutorialFlashSetup2009

arduino Fio and 5v sensors

does any body has use a 5v sensor on a arduiono Fio
I just got my in the mail and seems that operation voltage is 3v.
I am thinking to use forcensing resisitors with this board.

thanks in advance.
