Until you get to the car being autonomous, I don't see how any of these involve any electronic development or anything involving Arduino. I would have thought that a gas propelled tennis ball launcher was a very expensive solution in terms of money and...

Re: Wirelessly control motor HELP

The arduino will be transmitting information that it is receiving from a flex sensor (link: http://www.sparkfun.com/products/8606) this information will then tell the motor how fast it needs to spin, only has to spin in one direction, its a brushless o...

Solo un suggerimento ... vero, si possono usare degli HC574 o simili con delle resistenze, ma in questo modo la corrente e' comunque limitata ...

Invece usando integrati diversi, come ad esempio il DM135 http://www.daleschroeder.com/Ebay_Sales/DM135B/...

Re: control without port forwarding

OK, I've done some testing. I've set up my linux box to have Apache also listen to a non standard port. Next I wrote a sketch combining client and server sending and receiving on that same port. So when the client on the Arduino connects to my Linux bo...

A list of basic precautions to follow ?

Posted: 07 Apr 2013 02:57 AM PDT

Hello,

I am reading the book "Arduino Projects Book", included in the Arduino starter kit.

I've made an engineering school, so I've learned the basic of electronic. But it's a long time ago. I remember the general equations (U=RI, P=UI...), but ...

Re: Connecting batteries for longer work time ?

Posted: 07 Apr 2013 02:57 AM PDT

Most of 9V Battery have Capacity about 400 to 550 mAh, if you can last for 4 day, that about 100mAh pre day.
So for a month you will need 3100 mAh battery or 3.1Ah battery. If weight is not your consideration, you can use SLA battery,
but if you need ...

Re: using debounce

Code:

void loop ( void )
{
unsigned long time = millis();
if( time-dimmer.last<TIMEBASE )
return;

A couple of observations
1. This code will block execution of the loop() function which may not be such a good idea in many cases
2. Why...

I have the code doing what I wanted to originally do. I was missing a key aspect of the function crossFade, it is what set the previous value to the current value which made the lamp flash. Im still trying to figure out how to get the button to remain ...

Allen, thank you! This helps explain the use of strtok() but the byte option may also help with a memory problem I am having!

Thanks again!
