In preparation for NI Week 2017<\/a>, and with the help of LabVIEW<\/a>, LabVIEW MakerHub LINX<\/a>, and the chipKIT WF32<\/a>, I was able to make an improved version of my touch sensitive piano. This new version allows you to pick between 9 different sound profiles and makes it easier to turn any conductive surface into a soundboard.

This circuit works as a voltage divider (simple drawing shown at the bottom of the picture above), with one of the resistors (R1) being the 2 1M\u03a9 resistors in series and the second\u00a0resistor (R2) is the resistance of your body. The switch shown above is closed when you complete the circuit.\u00a0Let’s\u00a0say you hooked the gator clip to a\u00a0banana\u00a0when you touch the banana you are closing the switch and lowering the voltage read by the analog in of the\u00a0WF32<\/a>\u00a0(Vo).<\/p>\n

My LabVIEW <\/a>VI allows you to pick from nine different sound profiles, each containing 9 different sounds. The different sound profiles are shown in the picture below.\u00a0\"\"<\/p>\n

Thank you for reading my blog post, I look forward to seeing everyone at NI week. If you are interested in making this yourself but don’t have the right supplies you can purchase the\u00a0LabVIEW physical computing kit with chipKIT WF32<\/a>. This kit includes a copy of\u00a0LabVIEW 2014 home edition<\/a>, a\u00a0WF32<\/a>, and everything you will need to run\u00a0LINX 3.0<\/a>\u00a0and start making projects.\u00a0Please comment with any questions or comments you may have.<\/p>\n
