I own an handy-board now for 2 months and I have now 2 GP2D02 connected to it. (took me 1 hour to hook them up and test) You need a digital output-pin(like one off the spi-pins) or make use of the expansion-board, which has digital outputs. I (...)

I don't have IC handy, but you should just be able to do a hard cast. float aFloat = 1.3; int anInteger = 0; anInteger = (int) aFloat; /*cast the float to an int */ /*you can also do it in a function call*/ FuntionTakesAnInt( (int) aFloat ); Hope (...)

try running the servo off of a separate power supply; e.g., 4 AA cells. you'd connect the servo red wire to the battery + lead, the servo black wire to the battery - lead, and also connect the battery - lead to the HB motor ground. in general it is (...)
