  1. Paul,
    I got your audio Amp a while back to use it in haunted house sound effects. Your tutorials don’t show anything about it so can i ask how to send the board sound files from an arduino (BBB) board? What would be the max output wattage?

    • You’ve got to have a source of audio – for the audio in input. You could easily use the shutdown pin to turn the sound on and off.

  2. Can I use your 17.00 hot wire wind sensor to retract my awning when the wind his 10 mph or more. Can I internally adjust the wind speed that will trigger the awning to retract? Thanks for your response.

  3. AMBI Light Sensor
    How to get the reading in lux. From the note, the reading is from 0 to 1023, which will be difficult to indicate weather it is dark or bright.

  4. HI,
    I would like suggest to Modern Device creates a Google Plus account and/or include a feed link (atom or rss) for the news.
    Best regards

  5. Looking for a 0 – 5VDC current sensor, most are -5 to 5 V. Interface to the Hall side with solider would be great. You guys have anything like that coming??

    • Look at our current sensor – 0-5 volts, dead easy to use.
      Downside – it’s AC coupled so only works on AC
      Not sure what you mean about interface with solder.
