Instructables

Step 7: Finalizing It All

In this instructable you learned how a keypad is read, directly connected to your microcontroller, and also through a 16-key encoding IC. I showed you how to reduce the I/O burden on your MCU through the use of the chip, and gave several code examples (and the code itself) for you to try out and practice at home (or work, or wherever you're reading this).

I hope you enjoyed it! You are always welcome to email me, or if you find yourself on irc, pop over to irc.freenode.net #instructables.

Keep on instructing!
