Thanks. I will try this.

Will a shift register like this accomplish what I'm talking about?

They are analog inputs.

What I an trying to do is establish a field of about 24 thermistors. There is not enough analog in pins for this even on the mega, so I was hoping there was a breakout board that would be able to receive code from multiple sensors and feed it to the controller so I can control servo outputs based on a certain algorithm for the analog input matrix.

In the simplest form I want it to be able to detect which thermistor has the highest reading. I could take the rest of the project from there, but the hardware to set up that matrix is eluding me.

Would you have any resources for how I might accomplish this through ICs? The catch is that I can't have them read one at a time like you said, I need it to read the whole matrix, and identify the highest read.

Hello everyone,

I am trying to figure out how to control a matrix of thermistor sensors. I see there is an example of what I'm talking about for Servo motors, but I don't know what to search for to find something like this for analog inputs.

Any suggestions?

I must have been reading the page for the 2560. My mistake. Thank you I will try that. I just noticed it is the FTDI usb myself.

I have listed:

FT232R USB UART
Apple Internal Keyboard
IR Receiver

BRCM2046 Hub

Built in Isight

Internal Memory Card Reader

I dont think the FT232R is it but that would be the only unknown device showing. I do have the board plugged in and the L LED is flashing with the PWR led on.

Hello,

I am trying to get my SainSmart development board for Arduino ATmega1280 running and I am having some trouble getting it running. It doesn't seem to find an appropriate serial port as my Arduino UNO does. I have tried downloading Arduino 1.0 as it says on another post on this forum but I think I am all out of other avenues to trouble shoot. I hear it could be a driver issue as well, but no one has linked a place to find appropriate drivers.

I am using Arduino 1.0/1.0.1 on Mac OSX Snow Leopard.

Any ideas for why an applicable serial port is not showing up when I hook up my board?

Thanks,

Kevin
