activity LED for serial IO and/or I2C
![Zoot](https://forums.parallax.com/uploads/userpics/559/nW4UO23UEIWZ4.png)
I've got 2 mounted LEDs on the front of my project that won't get hooked up to pins. Could I hook one LED up to my serial I/O line and one to my I2C SDA or SCL line? Would I get any adverse effects on my data I/O? I was thinking of behavior along the lines of the green "act" LEDs on the PSC and the Ping, or like the disk access light on a desktop computer.
There is a circuit kind of like this in Robotics with the Boe-bot, p.48., for monitoring servo signal pulses. I was thinking a bigger resistor (1k) for a dim LED.
