[TriEmbed] ESP8266 Programming tip

[Carl Nobile]

John,

So I assume you need a delay there, so what you can do is use an interrupt
in your delay. Then the delay is managed between all other interrupts.

I found this simple example of using an interrupt as a delay. It' uses an
Arduino, but the concept may help.
