The term "Arduino" now covers a very wis range of computers at are all programmed using the same easy to learn system. You can use the "uno" whig is the standard 16Mhz AVR CPU or now you can swap in a "due" with is a much faster processor. But I doubt you would need a lot of CPU power as you are not re-computing this at a fast rate. The "Slow" AVR chip executes 16 million instructions per second. More than enough for what you want. But I think yout would be more concerned with power. There are far better chips that are just as easy to use. I'd look at TI's MSP430. It is failly powerful and can power down to run in just micro amps (yes uA, not mA) TI sells them on a development board just like the Arduino for $10 shipped. That is 1/3rd the price of an official made in Italy Arduno. The MSP430 LauchPad from TI can be programmed with the sme software environment as Arduino. Another advantage is that in TI's board after you program the prototype the chip is socketed and you can pull it out and run the bare chip See photo in link below. There are some jumpers you cn pull then the chip is electrically isolated from everything but power, you check it out that way than pull the chip from the socket if yu like. http://www.ti.com/ww/en/launchpad/launchpads-msp430-msp-exp430g2.html#tabs Use this to program the above MSP430. If you know the Arduino then there is zero learning curve. http://www.energia.nu It will run a long time on AAA batteries. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
