Hi. A couple of years ago I did an Arduino project for home automation, where I can read room temperatures, room illumination, read data from my electricity meter and control devices using 5V 433 MHz receiver and transmitter. All collected data is uplo...

You may want a second loop in setup to make sure they're inputs ( they are, by default, but if you wanted outputs, you could lose some hair chasing that down)

First off all insolence to is completely unnecessary especially to someone seeking advice.

Because you ask for advice and then go on to ignore it. You could have solved your problem if you followed what I told you days ago.
Why ask for a...

Well, "good news":

Doing the loop back, things are ok.

So now onto the next step in working out why this board doesn't work.

Just another thing:

The LED - pin 13 - cycles slowly from off to on and back - usually.

I also can't even upload the basic BLI...

How does one begin SMD soldering?

Posted: 01 Dec 2012 01:22 AM PST

I have looked at many design recently--like all the Arduino clones on Kickstarter and pretty much any prototype circuit--they either use breadboards and Arduino shields or complete SMD components. I understand that SMD components are used because they ...

It is ready and it works flawlessly! Thanks guys for your help!

PaulS: I have to apologize, you were right; it is better to use "while(Serial.available()){", and I could go down with the delay as low as 2 microseconds.

Here is the final code:

While that is what the spec sheet says, this is only true when layer out on a PCB with ground plane and terminated correctly. In other words it is the best you will get not what you will get.

No, what makes a wave interesting is not so much it's waveform but how it's waveform changes over time. That attachment shows the iPad app that allows you to draw the envelope of each harmonic in the wave. As you do that the right hand side shows the r...
