    Hello,

    I’m new to this and I’m not sure what Arduino to chose with the N18 kit.
    What are the limitations of the Uno vs the Mega ?
    Put planely, Why would I need the Mega over the Uno ?

    Thanks !

    The Mega enables more functionality on the clock. For instance, if you want to use the IR (infrared) sensor with the remote control, you can only do this with the Mega. The Uno also does not support the GPS for automatic time sync. Otherwise, the basic clock functions will be the same with both Arduino options.

    Thanks for the fast reply !

    Do you see an issue with the clocks ability to keep time ?
    I don’t need a remote… but im not sure if I “need” the GPS option…..

    Your thoughts ?

    The boards are equipped with DS3231 Real Timer Clock (RTC) chips, which are temperature compensated and pretty much the most accurate stand-alone chips you can get. They are accurate to within 2 minutes a year. Having the GPS is cool, but certainly not necessary. Also, if you go with the Arduino Uno, you can always upgrade it to a Mega in the future.
