Re: Aquarium Monitor using this board possible??

What you are after is very easy to do actually. I have something similar using a 40x2 character LCD. Changing it to suit a graphic LCD would be fairly easy.

You would also need the RTC module for your time.

Re: RGB Module

I have attached the sub program i use to write to my LED. What you do is do "post_frame" for every led, one after the other.. like this Post_Frame( long RGB1); Post_Frame( long RGB2); Post_Frame( long RGB3); Post_Frame( long RGB4); for each LED in your string. At the end, delay(1); which will let th...

Re: IR Sensor

Can you post your sketch for us?

You did download the library did you?

Did the program actually compile and upload to the arduino? or did it fail before that stage.

Re: Eleven connection issue

You probably have a barely capable USB port, or are just running close to the voltage cut out.
Try using a shorter cable, thicker cable, different port, or use a 12 volt adapter into the board that reduces the load on the USB cable.

Re: Help needed please

No, the capacitor in this circuit is only a timing element. It can not provide anymore then 12 volts.

In fact, due to that circuit being an "emitter follower" you wont get anymore then 11.4 volts due to the nature of the transistor.

Re: Help needed please

Thats it yup.
You could replace the switch with a toggle no problems at all.

The only thing to watch out is how much current your LED string takes, beacuse during the fadein/fadeout the transistor may get a little warm depending on how many leds you have.

Re: Help needed please

yea thats the kind of thing the arduino was designed exactly for :) however you can kind of fake it using a transistor, some resistors and a fairly large capacitor. You set up the transistor as a simple switch, and put a capacitor between its base and earth. Charge the capacitor with a fairly large ...

Re: Help needed please

Ok your setup will work fine. Get your diode cathodes and hook them up to the positive line after each switch. Then wire up all the diode cathodes to one line, and have that line go to another switch thats connected to your power supply. When THAT switch is turned on, each one of those diodes will f...

Re: Help needed please

If you wire the switches as switching to earth, yes that is correct.
