Firstly I would like to thank Ray for his hard work in starting off this excellent post! also for Eric and friends for the various coding updates.. I have made a few changes to the code and managed to get a working turntable on my layout, including an OLED display to show the position and head/tail indication. I only have 4 positions on my turntable and I didn’t use the servo brake or manual pot but left these functions in.
The display I used was a 1.3″ I2C IIC Serial 128X64 OLED LCD LED Display Module Digital for Arduino W which can be obtained easily on eBay… the driver for this is U8glib.h https://code.google.com/p/u8glib/ and the other components as mentioned by others I ordered from Proto-pic.
The revised coding is as follows, pictures to follow…
