hmm..very strange, that code is simple as you can get and worked for me. but if you get multimeter try to see if you have voltage in output pin 9 and also in 2 and 7 pins or just in one of them. these last two as to do with current direction.. they cant be both high or low or motor will not spin.if both are getting voltage ,schematic is like in arduino book and code is that one i showed you,you might consider damaged H bridge. cumps
