Brew Bubbles Controller Bracket

This bracket supports the [Brew Bubbles](https://www.brewbubbles.com) project.

The bracket is intended to position the Wemos D1 Mini and shield with photo-interrupter such that the bubbles in the airlock will register and be counted. The hole may need to be adjusted larger or drilled out depending on the size of your airlock. If it is too loose around the airlock, a drill stop or even tape may be used on the down-tube under the bracket to hold it in place.

There is a hole in the side intended to allow using a pop-rivet or small screw to secure the temperature sensor cable(s) with an [R-type cable clamp](https://www.amazon.com/InstallerParts-Pack-R-Type-Cable-Clamp/dp/B01DEX6J4U
). This is recommended to avoid strain on the small wires.

- Three different ways now to secure the bracket to the airlock
- Added a small hole for an optional M3 set screw
