Wire.onReceive(handler)
// Registers a function to be called when a slave device receives
// a transmission from a master
// handler: the function to be called when the slave receives data;
// this should take a single int parameter (the number of bytes read
// from the master) and return nothing
// e.g.: void myHandler(int numBytes)
