This post is grossly overdue.
I purchased two Pinduino kits from Eric before Mr. Smith Went to Washington (https://pinside.com/pinball/forum/rss/topic/professor-pinball-goes-to-washington-dcalexandria). One for Spider-Man VE and one for Metallica (Pro).
I had some questions about installation wiring (LED strips installed on back panel and apron) which he promptly answered via email/text.
Here's some tips:
1. Remove your back panel row of LED lights. At first, I was underwhelmed with the Pinduino light effects until I realized the back panel lights were washing out the LED strips (which I should have remembered the additive effects of wavelengths from physics & opto classes).
2. Clean surfaces where you will place the LED strips with rubbing alcohol prior to attachment. This will help with adhesion of the strips - more on this below.
3. Placement of back panel strip of LED lights. They need to be low enough to light the playfield but high enough not to be seen, otherwise you'll be blinded. For MET this placement was above the row of back panel sockets. For SMVE it was over top of the sockets.

4. Placement and adhesion of LED strips on the apron. I chose to put the strips on the outside of the apron. Others, like HankScorpio put his under the apron. Even with cleaning the aprons (SMVE smooth metal, MET textured polymer) with rubbing alcohol, the strips had trouble staying attached and began to peel away.
I carefully pealed the strips off the next day. I re-cleaned the apron surfaces with rubbing alcohol, preheated the apron surfaces with a heat gun (be careful not to melt the plastic aprons), pressed the strips on firmly and heated the strips again with the heat gun and applied pressure while warm.
Professor Pinball recommended using Scotch ATG Adhesive Transfer Tape 976 Clear, 0.25 in. It's been out of stock for months on Amazon, and ebay has been a bust. I'm still waiting.
The good news is that the heat gun method appears to have worked well and the strips have not separated from the apron.
A final note on the apron placement - I'm not sold on the strips being on the apron. I find them almost too bright and they can be distracting. I'm debating whether or not to remove them.

5. The Pinduino sketches. These were complete and functional for both SM (used on SMVE) and MET.
For MET, I was not happy with the stock blue color for the "electric chair" and the stock red for "electric chair insert" and "electric chair spot", for the Sparky effect, so I changed the color to Ice Blue, which matches some of the comet bulbs I used.
For reference, I changed the following from the MET sketch for the colors:
FROM pd.adrLED1()->color("red", 255); //original sketch TO pd.adrLED1()->colorRGB(212, 240, 255, 255); //ice blue version 1
and
FROM pd.adrLED1()->color("blue", 255); //original sketch TO pd.adrLED1()->colorRGB(212, 240, 255, 255); //ice blue version 1
This is a fun little modification. I hope to create some custom code in the future to change the effects.

Apron lighting- I ended up duplicating the code and running the apron lighting separately ( the backboard and apron lights are now on distinct outputs) for MET. This was done to lower the intensity of the Apron lighting.
