Our doorbell was already connected to the Internet via an Arduino, but we couldn’t stand the sound it made. We needed a warmer sound, a sound that didn’t make us want to kill the doorbell users (mostly clients).
Buy an old Wind Chime, preferably with a coconut base (because awesome).
Pick up a few Littlebit modules (Cloudbit, servo motor and power supply).
Drill, glue and duct tape a bambu stick to the servo motor. Hide all the crap in a classy box.
Make the old Slack door bell script also make a little curl post to the Cloudbit.
Ring the door bell. Voila!
