My garage is 20 ft x 30 ft. (That's about 0.01 US [Imperial] football fields and an indeterminate number of metric [FIFA] football pitches.) The original lighting in there is 3 connected ceiling-mounted sockets. That's enough light to walk through there without risking your life, but it's very poor lighting for actually doing anything in that garage.
It's easy to find many descriptions of people putting up inexpensive 12V LED strips in garages or other places. So, hey, me too! I'm not bothering with describing much of that part of the project because there is nothing special about my take on it. This project is about the controller I am making for it.
Here's a high-level view of the features:
- Two remote passive infra-red (PIR) motion detectors to keep the lights from timing out while someone is present.
- Two remote control knobs consisting of rotary encoders with built-in momentary switches. These are both on/off switches and also dimmer controls.
- The PIRs have LEDs for debugging/feedback.
- The control knobs have LEDs for easy location in the dark.
- Sensors for temperature, air pressure, and relative humidity.
- A built-in touchscreen display. (Not planning to implement the touch part in software.)
- SD card slot for possible data recording. (Not planning to implement this in software.)
