PKE Meter - GB1 Hero Version - Electronic Components & Digital Files.
This project took 7 months to complete & it all began with me looking on the internet for an accurate 3D PKE Meter to print, only to find that it didn't exist. I decided I would try to make one & tracked down some amazing PKE references online and based my 3D model on those.
After a few weeks I had a 3D model of the PKE Meter that I was happy with & thought I'd add an Arduino Nano to the model to sequence the LED’s, Servo, etc. It took 3 to 4 months of hard work to finally create a working Arduino sketch. The last piece of the project was then to source all of the component parts & sound files etc to complete the project. The 3D model was successfully test printed & all of the component parts fit & work as designed, please watch the short demonstration video of the finished version.

NOTE:
Files with “1.” & “FDM” in the title have sacrificial layers built in that reduce the amount of support material required and reduce print time by almost an hour and a half but are only for use on FDM printers. If you are printing the PKE in resin, or just don't want the version with built in sacrificial layers, use the version of the file that starts with a “2.”

GB1 Hero IONA - Arduino Code
The sketch controls the LED’s, Servo & sound effects by pressing one of 2 capacitive buttons.

*Stage1 - When neither button is pressed, the sketch will return the the Servo to the parked position, it plays sound 01 and sequences the slow speed version of the LED’s

*Stage2 - When “Button A” becomes pressed the Servo moves to 1st position, plays sound 02 and sequences the medium speed version of the LED’s and does this until the button is released, at which point returns to Stage1

*Stage3 - When “Button B” becomes pressed the Servo moves to 2nd position, plays sound 03 and sequences the fast speed version of the LED’s and does this until the button is released, at which point returns to Stage1

The buttons are programmed with a 1.5 second delay on release, this gives you time to press another button without the wings instantly returning to Stage1.
