Okay, today we are going try to build a computer controlled Christmas Lights in 5 minutes.
I’ve been rolling around the neighborhood this late November and some people already have
their Christmas lights decorated. Well I’ve seen many “static” Christmas lights that always
stay on. Today, I will show you how you can customize your Christmas lights by using a PLC,
a Programmable Logic Controller.
Update: Garrett’s Voice Activated Christmas Controller is now available!
- 1 CuSB22R from cubloc.com
- 1 AC power cord (like the one for your computer or get it here: cubloc.com)
- 3 AC Connectors from Home Depot (You can get more depending on how many Christmas Lights you are trying to control,
remember you can also put Christmas lights in series per relay)
- bunch of wires
First you will need to cut off the AC power cord and you will find 3 wires,
one green, one black, and one white.
Simply splice them and hook up the green wire to the CuSB where its labeled
“FG”, which is frame ground so your house does burn down.
Screw in tightly.
Then put the other Black and White wires onto the terminal headers as shown below.
Black and White wires do not have polarity, so you can put either or onto the CUSB
labels, N and L.
Leave them unscrewed and only screw in the green wire if you haven’t done so in Step One.
Connect a wire from CuSB label COM to CuSB label, N
Connect some Christmas lights to each of the AC connectors.
Then connect the serial cable to program the unit.
Copy and paste the following code into CublocStudio and download to your CUSB.
Const Device = CB280
Dim Interval As Long
If Interval>100 Then
Elseif Interval>0 Then
Taking It Further
Well your lights should be working pretty good now.
You can change the Interval=300 line so the lights start
blinking slower or make a completely different program
for your Christmas.
If you put it on a deer structure or something, you can probably
time it so it is animated.
But we will leave that up to you and if you have any questions,
feel free to email me: firstname.lastname@example.org
Happy Holidays! 🙂
