Von den Pollin-Motoren gab es doch einen linken und einen rechten. Von der Optik her hätte ich den genommen, der nach innen ragt. Ansonsten ne spannende Konstruktion, kommt noch ein Abdeckblech oder sowas drauf? smiley-wink Die Schraube sollterst du noch gegen ...

Can fusebits be incorporated into the hex file?

Posted: 08 Apr 2013 03:29 AM PDT

I am wondering if fusebits for the configuration fuse of Atmega328 can be incorporated into the hex file? If yes, then programming becomes more convenient as it can be done once. If no, then programming got to be done twice - first time upload fuse bit...

i use the 4x amplified outputs. also another questions do i have to apply 1.23 volts to the Vref? or is it an output? When i measure it with a multimeter i get 0V.
Datasheet says that i should connect the x1 outputs to Vref if i use the amplified outp...

Re: count character

Posted: 08 Apr 2013 03:05 AM PDT

The number of useful characters in the array is not 5. It's 4.

Google would have probably steered you in the right direction if you had search for "string length".

Of course, you really should have a book about C programming, since it is the foundation...

Re: Instruction for invert a PWM signal

Posted: 08 Apr 2013 03:03 AM PDT

To do this you need to directly affect the relevant TCCR register for the PWM pair in question.

On the Uno and other 328 boards the PWM pairs are (5,6), (9,10) and (11,3) - for timers 0, 1 and 2
respectively.  Assuming using timer1, pins 9, 10, then yo...

Re: Instruction for invert a PWM signal

Posted: 08 Apr 2013 02:32 AM PDT

A good way is to use the map() function: http://arduino.cc/en/Reference/map
Code:
invertval = map(val, 0, 255, 255, 0);

GPS doesn't work too well in most solid structures.
Even if it does work, it could still be many metres from where you expect it to be.

Well, since it is going to be on a glove it would need to be relatively small. I would recommend an Arduino Fio: http://arduino.cc/en/Main/ArduinoBoardFio
They are small, run off a 3.7v lithium-ion battery, charge via mini-usb and have a socket for an...
