Important note for audio files. Careful read notes below will save you a lot of precious time!
* DFPlayer Mini read both MP3 and WAV files.
* All audio files must be placed under /mp3 folder.
* Audio file must be named 0001.mp3, 0002.mp3.....0255.mp3 (4 letters not 2 or 3 letters)
* Audio file names can have any characters after 4 digits, such as 0001_Bruno_Mars_Count_On Me.mp3
* Audio file names can have any characters after 4 digits, such as 0001\_Bruno\_Mars\_Count\_On Me.mp3
* Tested few under 1 second WAV files and they did not work
* If one of the audio file is removed from SD cared, DFPlayer still can find it and play it! Weird! In the end, I formatted the SD card to make DFPlayer to play the music I specified.
* Delay(seconds); You have to specify number of seconds delay for the audio file to play completely or the next audio file might be started before current audio is over!

I also experimented a bit with stenciling and stamping patterns onto the textile. The acrylic is a bit thick so allows for this quite well on a tightly woven fabric. When just using water, or using acrylic paint that is diluted a little bit more, its nice to paint by making paint strokes with a brush. The creases of the cling film also left interesting marks on the swatch I painted with heavily diluted yellow acrylic paint.
It could be nice to do these measurements a bit more precisely, but for now this will have to do....Still have many circuits to make this week.

I added a 1N4007 diode (1000V-1A) for safety in case I want to use it with motors etc at a later stage. Never hurts to protect a circuit. I used this one because it's what I had in my box of stuff, but didn't have the 1N4001 (50V - 1A) Liza suggested. Emma wasn't sure why Liza would put a diode in series to one of the leads, instead of in parallel across the leads. We asked Liza and she said [...]
