Serial input on pin 2 of the 08m

Unfortunately, the Serial In pin on an 08M cannot be used as a digital input. The feature became available on 14M, 18M and 20M and of course, the M2 series of PICAXEs.

You have two options: upgrade to an 08M2 or, if this is your third input (Pin 3 and one other*), you could set up a resistor divider circuit and use the other* input pin as an ADC input. * "other" pin would need to be 1, 2 or 4.

Thanks I think I will buy some of the 08m2 and 14m2 chips. I also have another question can the picaxe run on 2 AA batteries?
