Re: Help needed with a common anode 8x8 rgb led matrix

Posted: 29 Apr 2013 02:43 AM PDT

$6 for a 8x8 RGB matrix is incredibly cheap. Can you share me the link for that?

You can get them even cheaper. Just search for "rgb led matrix" on eBay.

I'm not familiar with the pinout of these, why does it need 5 separate signals per display?

Do you have a data sheet?

You are right, I don't put in resistors to limit the current, but if that helps I have a lot of them lying around... I thought my matrix has its own resistors for each row, ...

Incredible Transforming Desk from the 1700′s

Posted: 29 Apr 2013 02:08 AM PDT

This incredible transforming desk literally has hidden passages inside its hidden passages.  At first glance, it looks like a beautiful, ornate piece of furniture.  But in reality, many of its shiny brass embellishments are actually buttons which open secret drawers.  Keep in mind all of this is achieved mechanically – No electronics were used.

But wait, there's more!  The crafsmanship doesn't stop with just one desk.  Here's yet another piece from the same artist:

The number of secret drawers and cubbyholes never ends!  Hopefully you're now fully inspired to build your own secret passages in your furniture or home.

Code:
if(280 < x <400 && 260 < y < 435){
Tell us what you think that does.

You have a "Serial.begin", but don't use it.
Serial debug is about the most useful tool you have.

Re: Use servo to push a 'real' button

Posted: 29 Apr 2013 02:10 AM PDT

Indeed, a solenoid seems better. How quickly does such a device extends? It says "action form: pull". I suppose this means "push" when actually looking at it like a person who wants to press a button?
Do you know if the Arduino Uno + LAN is the best wa...

Re: Controlling the rotation of Servo Futaba S3003

Posted: 29 Apr 2013 02:09 AM PDT

Is this a continuous rotation "servo" or a normal one ?
Can you provide a link to the actual servo that you are using ?

If it is a continuous rotation "servo" then myServo.write(pos) sets the speed and direction of the servo and it will keep turning at...

Use servo to push a 'real' button

Posted: 29 Apr 2013 01:54 AM PDT

Can I use a servo to push a 'real' button? So not flip a switch (as has been done before), but really push a button one or more times. For example a button on a phone, a button on the wall etc. If so, what servo would I need, and what minimum Arduino b...

Thank you Lakes, I understand how to make the LDR circuit.

Just to be sure I also understand how to make the LED strip circuits:

On my Arduino Uno there are three GND pins, lets call them GND A, GND B (both on the POWER side) and GND C (DIGITAL side) (...
