Can I connect stamps in series.· I have run out of input pins on my stamp.· I want to have to boards with two different stamps.· I want to use one stamp/board to support a tilt sensor and other sensors.· Then I want to send a signal from the tilt sensor support stamp to indciate that the boe bot is tilted.· I want the second boe-bot to recieve the tilt signal to know that it is tilted (and stuck on somethiing) and change its wheel commands.· Can I do that?

    There are some Nuts and Volts columns on networking Stamps.· I don't remember which ones, but it's useful to go through the list just to see what's available.

    For the sort of functionality you want you might consider putting the tilt sensors and the servo control in one Stamp and some of the other functionality in the second Stamp since the communication process takes a little time and you want the tilt correction to happen quickly.· Depending on what other functions you want to accomplish, you might be able to use just an input expander like the 74HC165.· There are plenty of examples of this in the StampWorks manual that you can download.· There's also output expansion possible using a 74HC595.
