241  Using Arduino / Installation & Troubleshooting / Re: UNO Driver not found for Windows 7 on: February 17, 2012, 05:16:07 pm
It works I'm running it on windows 7 64 bit

All i had to do was point it to where my arduino drivers are it used the the vista 64 bit setup to install the right thing
242  Development / Suggestions for the Arduino Project / Re: LiquidCrystal 4 bit mode initialization doesn't follow datasheet on: February 05, 2012, 02:14:12 am
There not using read write pin on the LCD so just to be on the safe side the delays are longer.

If you feel a shorter delay is better and it works use it. There are a lot of clones that need more delay.

It may work fine for you and my buggie LCD may not like it.
243  Using Arduino / Project Guidance / Re: About arduino duemilanove on: February 05, 2012, 02:04:39 am
It's adc is 5volt  and the only difference is how they connect to the pc the uno  uses a atmega16u2 for USB to serial and duemilanove uses a FT232RL and only has 5 volt power uno has 3.3 at 50ma and 5 volt

Thanks It was looking like that's the only way so Now I no thanks

I've looked around but have not found if you can use this code

Code:
int powOn = 3;

void setup () {
pinMode(powOn, OUTPUT);
}
void loop () {
     powOn = 1  // Is this usable
}
}

// or should it just be done this way
digitalWrite(powON, HIGH);   // is this the only usable way


I guess what I'm asking is can you just set a pin high by using a 1 or do you have to use digitalWrite for
outputs

He doesn't say if he using the pin as a I/O or analog

You want to hook your relay up as shown

It sounds like you have the diode backward

The chip is able to use 5.5 Volt supply. The data sheet said 0 to VCC

So if VCC is 5 volts then No i wouldn't use 5.25 on a ADC pin your reading would be off

I would use a 5 volt zener diode
