Thanks so much!!!
2  Using Arduino / General Electronics / Reset pin to ground Leonardo on: September 01, 2013, 05:25:30 pm
Hi, I need to install a second reset swicth to my arduino project. I want to use reset pin, I know that reset pin needs to use a low signal to reset arduino. I don't have any pins free to provide a low signal to reset pin. Can I conect the ground to a swicth and this to the reset pin? or how can I do that?

3  Using Arduino / Programming Questions / Timer to LCD display on: August 17, 2013, 07:13:11 am
Hi, I'm controling a stepper motor and at the same time I'm showing in the lcd the position of the motors in millimeters.
I have all code in a loop, and the clock of arduino can't move the motor faster because the lcd catch a lot of time to show the position. Arduino can't control the motor and the lcd at the same time.

There is any way to control the lcd in a timer and the motor in other way? I want to do multitask.

Thanks!!!!!!!! for the information!!!

Hi, I want to control a stepper motor with a driver a4988 and arduino and I ask: I can connect the ground of the ATX power supply 12V to the arduino ground? because I have heard that is very important to connect GNDs of arduino with ATX power supply and ground of a4988.
It's that true?
6  Using Arduino / Installation & Troubleshooting / Using resistances on: June 27, 2012, 08:26:01 am
Hi, I'm begginer in electronic and I connected a dc motor and a led to digital pins in PWM mode of the arduino board without a resistance (I connceted them directly), I want to know if do that is damaging for the arduino board or only is bad for the Led or the motor that use 5v, for that I think that the motor don't need a resistance. It's true?
