Stack them up just make sure that they all use different pins so you don't get conflicts.

Run it on one cell rather than two (or for longer life two connected in parallel). They will run down to 2.7 volts or 1.8 for the "V" series.
Clock may have to be lowered to something like 1 Mhz.

l'errore che mi segnala l'alimentatore dice che sovrascrivo il buffer di output, che nel frattempo non si è liberato(non invia i dati ad arduino);
duqneu il problema è che l'output buffer dello strumento non si svuota, non invia dati sulla porta.

Re: Lecture code infrarouge

Posted: 16 Jan 2013 01:09 AM PST

tu pourrais brancher un oscilloscope sur la diode IR de l'émetteur afin de déterminer quelle est la fréquence de la porteuse, déjà. Ensuite il serait plus facile de trouver un récepteur adéquat.

Re: hey guys, how come IDE is not working on MAC?

Posted: 16 Jan 2013 01:09 AM PST

Sorry, my bad, Mac then..
yea, i've tried to double click it but nothing happened. i have solved the problem by running 0023 version, however when i update it to 1.0, it's not working again, i mean when i double clicked on it, nothing happened.
Thx

Re: DC Motor torque control

Posted: 16 Jan 2013 01:05 AM PST

A method of "braking" a motor is to attach a DC motor (to act as a generator) to the shaft. Then you can electrically load the generator to produce whatever braking force you require. It's simple and it works !

Pins 0 and 1 are the hardware serial pins that Firmata uses to talk to the PC or other device driving it.

That's right. There are only a certain amount of pins that are PWM capable. That's because the timers that have the PWM module ha...

Have you seen the dictionary definition of recursion ?

good info,well if you calculate the torque X when the object is falling, you would need 2X the other way to raise it at the same speed,

Re: Hall effect module jitter.

If your system controls the device whose current you are measuring, then when you initialize the sytem you can take a reading with the device off (no current) and use that to establish the zero-current reading. Then you can subtract this from future cu...

A 10 watt LED would be blinding. If you look directly at a 10W LED at close range you would be seeing spots for a while.
