Nope - use the microcore. It will let you put "pause" neurons in between
motor actions.

Nope, the Microcore will do this quite well. Just make a single process
loop that activates your actions sequentially, then loops back to the start.

Someone asked for a resistor color chart a short while ago.
I have found two things;
1. http://www.dannyg.com/javascript/res/resload.htm
has a javascript app
which lets you choose a resistor color order and shows you what it
equals to.
2. attached is a GIF with a color chart.
PAT
P.S. do NOT send any messages to this address, I'm just using my dad's
while I wait for canada.com to fix theirs in a day.

sequencer with independent time step adjustments: two (turn left/right) Nv
stages per motor and one Nv stage for each "no motor running" delay. The
Bicore solution is a little more subtle : Use a master-slave Bicore for each
motor but with motor connected to one master output and one slave output.
The master controls the frequency and the slave controls the "on" time. For
more motors use "ganged" slaves to time each step of the sequence. This can
be an "open ended" chain if you want to have a delay between each sequence
or the last slave is looped around to retrigger the master and start a new
sequence.
