I got one of the NKC electronics Ethernet shields and I really like it. The only problem is that you cannot use it with other shields... on top of it... for example a LCD shield or xbee shield.
The ethernet jack is big making thing to connect impossible. That's not a problem with the shield per say... it's more with the prototype requirements. I wonder why NKC limit the size of the PCB, I think it it were a longer then most shield could fit on top of it.
Thomas J - When I initially try to run the example it did not work but I saw it broadcast in ad-hoc so I knew that the wifi was working. The reason it was not connecting to my router was because my router was working on G mode only. I needed to change to MIXED MODE (a/b/g).
So check that your router is working in mixed mode. This TIP should be added to the wiki too as long as the list of routers tested.
Hello - I have a project on which I need to interface with other devices.
I have 2 type of devices to talked from arduino. Those devices have only a 3 wires connector (data1, data2, GND). Device A is i2c and Device B is rs232. The ardunio will connect to only one type of device at time.
So my question is? Is it possible to wire the input to the i2c and UART pins at the same time and in the arduino I choose the port to listen? is it ok to have the signal on both ports at the same time?
Or should I better put a switch to only send the signal to the correct port? I'm trying to avoid the switch and control everything in software.
Also it would've being nice if the i2c pins could work with the software serial but I think PC4 and PC5 on the atmega don't work as a GPIO.
Hello - This is very cool. Is there a way to get an smaller size?
I'm currently using 1 potentiometer for a project but I would like add the "cool factor" and replace the potentiometer with an small touchscreen (2x5cm inch aprox) and some square leds behind to show the position?
The DS screen would be big for what I need so is there any other thing I can use and not necessarily a touchscreen per say?
