We (the company I work for) have need to use microcontrollers for occasional in-house projects and I have been involved in programming for a couple of commercial (closed) products. We don't advertise the fact we use a particular make of microcontroller...

Hi,

What range does this information need to be transmitted over?  Is there the possibility of utilising an existing Wifi network or do you need to provide the comms?

Re: Arduino to Arduino bluetooth communication

Posted: 15 Dec 2012 12:38 AM PST

Hi,

In my experience (granted, using Bluetooth Bees rather than any of the modules you've quoted) a range of 10m is fine, in line of sight.  When there are obstacles in the path this soon degrades, and they're prone to interference as you've mentioned....

Re: any fans of the Bascom AVR ?

Posted: 15 Dec 2012 12:38 AM PST

Regarding Bascom, there can be a disadvantage. You can not perform "complicated" math on a single line.
You can not have something like:
a=b*(c+d)
Such an operation have to be decomposed in two lines (parts):
a=c+d
a=a*b
which looks somehow ugly and u...

Posted: 15 Dec 2012 12:16 AM PST

Hi,

Sounds like you've set yourself quite an ambitious challenge.  If the device is hard-wired to expect the firmware update on the USB port, it's not going to be able to natively expect one down the ethernet from a USB device shared on a PC.  So whate...

Power leaking over analog in?

I'm having a puzzling problem. I have an Uno board with an LCD shield. There are 3 sensors connected to analog input pins. It is reading all three sensors just fine. By accident, I powered off the arduino before the sensors, and I noticed that the LCD ...

Thanks for your reply. But we have a slightly different Uno board.
 
My reset button is beside the USB port.
