I connected the power supply and the LilyPad. The resistance of the conductive stitching needs to be less than 10 ohms between the power supply and the Pad, I borrowed a multimeter from Generator and measured about 4.5 ohms, so all good. I laid out the LED's, marked everything with chalk and sewed the positive terminals of the LED's to the Lilypad. I ordered some stitching glue and puffy fabric paint (insulator). Soon I will download a program to the Lilypad and see if the LED's actually blink like a turn signal. If the do, I'll start gluing things down and insulating the stitches so they don't short.
Also, every time I come down here I run into someone who helps me advance the STEM Academy along. It's nice to be in a place where people have interests similar to mine and are willing to help.
