Customizing GOL to be turned on/off by external signal

by VNAtmai on Thu Jul 01, 2010 3:18 pm

What's the simplest way that the GOL could be modified so that it can turn on or off by receiving an external signal? In particular, I want the GOL to turn on and off in response to another device drawing current. The game and another device would be receiving power from the same 5v power source; when the other device drew current, the game would detect this and turn on a for a few seconds with a random seed.

I was thinking one way to do it would be to use one of these current sensor ICs:

For easy prototyping, the sensor could be on a small breakout board tied to the wire leading to the other device with plastic zip ties, as in this engineering kit:

A wire could lead from the little breakout board to one of the pins on the GOL board and thus send data to the processor. But is there a simpler way to do this, possibly by modifying the on/off switch? I don't need a lot of sensitivity and precision, just for the game to 'know' when another device on the same power supply draws current and turn on in response.

It would be nice if this could be done without requiring the processor to be on all the time as well, which is why a modification to the on/off switch would be good if it were possible.

Thanks for any advice.

If they are both driven from the same power supply, why not just wire it so that one on/off switch serves both devices?

It's not a matter of turning the other device on and off -- during use, it will constantly be on, but sometimes it will draw more current than other times. The GOL cube is intended to provide visual feedback to the user that they will notice when the other device draws current.
