Has anyone built the pack lights using a Basic Stamp Micro-controller? I have acquired one and I am now trying to quickly implement it before Halloween.

Here is the program I worked out. Not the cleanest but it did the job.

Main:

LOW 0

```
PAUSE 100

HIGH 4

PAUSE 100

HIGH 5

PAUSE 100

HIGH 6

PAUSE 100

HIGH 7

```

HIGH 0

LOW 1

```
PAUSE 100

HIGH 8

PAUSE 100

HIGH 9

PAUSE 100

HIGH 10

PAUSE 100

HIGH 11

```

HIGH 1

LOW 2

```
PAUSE 100

HIGH 12

PAUSE 300

```

HIGH 2

LOW 3

```
PAUSE 400

```

HIGH 3

```
LOW 12

LOW 11

LOW 10

LOW 9

LOW 8

LOW 7

LOW 6

LOW 5

LOW 4

```

GOTO Main

What are your pins hooked to?

I reallize that that seems to be a simple program but using that many high/low commands kind of bogs down the Stamp and uses tons of memory. I’ve been using the Pics myself and have run into that problem. Another thing you might run into is overloading of the ouputs too much current will fry the chip.

Personally I like to use the Pics /Stamps for circuits that I can’t build or control using conventional electronics. I’m thinking you are using the stamp to control the scrolling light bar which can easily be built without the stamp. Now the gun lightbar can also be built without the stamp using a LM3914 and a triangle wave generator.

The [Cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron) lights are hooked to IO pins 0-3. The bargraph are pins 4-11 and 1 light in the gun is pin 12.

As to the question of overloading. I am using NPN transistors to switch power to the LED’s so the stamp is not directly driving the LED’s.

I realize I could have done it with a simpler circuit but I could not find the chips I needed in the short time I had but I did have the Basic Stamp handy.

It also did work perfectly.
