Ir Ranging added to control delays

I added a couple more lights so you could see the effect better. I still have one output that isn’t being used yet. Also I added a couple of ways to vary the delays in the chase sequence. The first was a Potentiometer, the second was a Sharp Infrared Ranger. I am using the value from the ranger to determine the amount of delay in the chase sequence. You could also take the range value and break it down into windows and turn on individual outputs based on how close you are to the ranger. Here is a video of the Ir setup controling the delay.

Here are a couple more pictures:

I think I have about 500 of these assemblies that have the 4 output board and an intel 87C51 Processor.

I am not sure how many of the 8 output boards I have but it is in the hundreds as well.

Another note, It is possible to control 220v devices with these boards as well. The 4 outputs are paired so that you can provide a seperate line voltage to each pair. Here is the PDF file for the Triac’s that are used on the board. datasheet

    Honestly, I feel I haven’t done it justice so thanks. I am mostly just trying to capture the ramblings that spew from my head before I forget them.

    Thanks Gail, I use WordPress. It is by far the easiest and most powerful publishing software I have used. If you want to do this kind of work I highly recommend checking it out. Oh, and it’s FREE with my hosting package. My host,, makes it extremely easy to get it installed, just one click and you are up and running. As for learing code, the Arduino is also one of the easiest Microcontroller platforms to learn to program in. Thanks again for the kind words and good luck.
