Using a rotary encoder as a volume control for the Raspberry Pi

Using a rotary encoder as a volume control

On my RetroPie machine I wanted a hardware volume knob — the games I play use a handful of emulators, and there's no unified software interface for controlling the volume. The speakers I got for my cabinet are great, but don't have their own hardware volume knob. So with a bunch of googling and trial and error, I figured out what I need to pull this off: a rotary encoder and a daemon that listens for the signals it sends.

Rotary encoder

A rotary encoder is like the standard potentiometer (i.e., analog volume knob) we all know, except (a) you can keep turning it in either direction for as long as you want, and thus (b) it talks to the RPi differently than a potentiometer would.

I picked up this one from Adafruit, but there are plenty others available. This rotary encoder also lets you push the knob in and treats that like a button press, so I figured that would be useful for toggling mute on and off.

dsisnero / Import Contacts from Slack.js
Created August 2, 2019 18:27 — forked from simonbs/Import Contacts from Slack.js
Scriptable script that imports contacts from Slack. Existing contacts will also have their avatar and social profiles updated. The contacts must have their phone number set in Slack.
// In order to use the script,
// you must create a Slack bot
// with the user:read scope and
// generate an accesss token.
// The script will prompt you
// to copy the access token in.
// The token is stored securely
// in the keychain.
let containers = await ContactsContainer.all()
let contacts = await Contact.all(containers)
