Electronics Bash - #16 - Hardware Interrupts

Writing interactive code without interrupts can be like waiting for a letter to come - you have to keep checking the mailbox to see if any new info has arrived. Interrupts are like an alarm on your mailbox that draws your attention so you don't need to keep checking. They're powerful, useful, and a little finicky - they'll be our subject this week.

Topics Include:

--Interrupts
--ISRs
--The 'volatile' quantifier
--Timers

Grab a cold one and come join me live as we make stuff every Sunday night at 7pm CDT. Bring your projects, bring your questions, bring your ideas for what we should learn or talk about. Let's hang and talk about something other than hand washing. See you there.
