The photos from the parade!
The parade was a lot of fun and definitely worth the effort we put into make the costume.
Embroidering the heart – we created the graphics in vector and used the embroidery machine to stitch the outline of the heart on the fabric. We learned that the density of the stitch is very important as it broke the needle while stitching! Testing the density and how stable the tension is imperative.
Testing the circuit for two LEDs fading
The code used for the two fading hearts and LED strip in between the hearts that goes back and forth.
