Mother board picaxe 28

The servo motor is attacked to digital pins.  How do they recornize the 75 and 225 comands? I thought digital pins could only take high and low comands?


One of my students reveresed the wires of the sharp senor and it fried the sensor and looks like it fried the IC 28 because the picaxe programer will not recogine it any more. Question is, has the mother board benn damaged also?




In installing the L293 motor driver I put it in the resister slot and the DIL 330 x 8 resister arry in the motor driver slot.

Will this have damaged them.  After I righted them, the robot is eratic in its exacution of the comands of code.
