Home automation system overview

It occurred to me that anyone coming here can’t see inside my head and probably don’t know my overall design for this system. Honestly, neither do I at this stage but I have a rough idea. Every development project changes as you go, especially when learning new things. Here is my design as it stands…

16 channel PWM Dimmer code

Managed to find some time over the weekend to get some coding done for the dimmer (was called “controller” but I thought this would be confusing in the end so now it is “dimmer”, more theatery). The Dimmer .ino and library now works and can do: Independently control 16 LED channels of high res (0-4095)…

The Dimmer

I played around with a few setups for the part of the system that will actually control the LED lighting but everything always ended up messy from a cabling point of view and, as all good development projects go, unmaintainable for anyone else let alone useful for anyone out in the world to try an…

PWM breakout

After starting off thinking that the on board Arduino Mega’s 14 PWM pins would be enough, I quickly found that this would never work. Apart from The starting limit of 14, pretty much any extra shield you plug is wants one or more of these pins. Ethernet shield wants pin 10, SD reader wants pin…

Here’s one I prepared earlier

Skipping ahead a little bit, I have run all the cabling for lights, switches and networks. For switches, I was using CAT5 Ethernet cable but int he end didn’t like it for the use even though it would be greatly flexible for future additions of POE (Power-over-ethernet) networked devices for control but I figured that…

Another one rides the bus

Normal 240VAC lighting is usually setup that the power starts at the switchboard, goes down the wall to the switch, a feed for the next room/light and the light feed go back up the wall and to the light. This hasn’t really changed in recent history with the exception of inline control devices that add…

12VDC or bust

Starting off down this road, you can very quickly get bogged down in scenarios. What if you already have house wiring, can you /should you retrofit, can you go all low voltage, what if you aren’t there to fix it? This started to kill the project before it started but with a bit of looking…
