Hi mackrackit

I've metered GPIO.0 out to the pot, it does seem to be connected(getting some strange readings though).

I then changed the cable from GPIO.0 to GPIO.4 (and the program to reflect the change) when I send from the serial communicator two LED's briefly flash on then off ( pretty quick though).

I increased the pause time from 250 to 2000, still only a brief flash but definately
flashing!
