    Multi-task Your Arduino

    Great explanation. I have a project where I'm flashing 110 RGB lights (essentially 330 different LEDs), in various patterns on a star shape object I made. Every one of my functions has delays between the on and off of the light flashing, and I have, so far, about 10 of these functions., eg here's one function. void BlinkSpinAccel(){ for (byte k = 0; k < 3; k++) { PORTB = rgb[k]; for (int i = 0; i < 10; i++) // for (int p = 0; p < 8; p++) { CS.portWrite(p, 0xFFFF); delay(DelayArray[i]); CS.portWrite(p, 0x0000); delay(DelayArray[i]); } }}How should I approach this using your interrupt technique? I want to simultaneously rotate one bunch of LEDS one directions and another bunch the other direction. The function above has an array wi...

I want to simultaneously rotate one bunch of LEDS one directions and another bunch the other direction. The function above has an array with increasing values in it so that the delay changes on every pass, but most delays are just "delay 200;" I'm using centipede (CS) library for my I2C commands, writing to 7 port expanders. in an LED matrix. (Port B handles the 3 colors).

    Battery powered fog machine

    Yeah, you're probably right. I used that example because I was a smoker...28 years ago. Use a candle then. Light the candle, blow it out when close to the offending leak and watch the smoke. A lighted incense stick works too.

    To check for heat leaks, use a cigarette. Don't inhale. Lot cheaper than using this device. I like the idea of this unit for my model train layout, smoke from a "campfire" for example.

    Inexpensive garage lights from LED strips

    would it pass building codes? Not likely since the technology is new and no one has rules for using such strips. If you need a building permit to make a building, inspectors would likely reject this addition. The power supply, wiring, exposed LED strip components would all be suspect. Is it more a fire hazard than UL approved fluorescent lighting? I myself don't have problems with it since I use LED strip lighting for my model train layout. Oh..12 volt supply by the way.
