Has anyone come up with an electronic solution to the problem of only having
3 out ports?
It seems it would be possible to control many more motors if some sort of a
multiplexor was constructed,
maybe the motors could use their own power supplies and use output ports as
inputs to the multiplexor.
I just joined the list so sorry if this topic has been discussed :)
Also, has anyone developed a sensor using a digital compass?
