I am a complete beginner in Arduino, but I do have limited knowledge of electronics and programming.
I am trying to make a projector clock using Arduino.
I started from an existing clock by dismantling its projector and found the LCD (LCD NOT LED) screen is driven by a TM1621D controller. I did not touch the ribbon connecting the controller to the LCD screen.
The projector connects to the board with a 5 conductor ribbon. On the board the pins are marked: 1.+VDD (red wire) 2.GND 3.SDA 4.SCL 4.CS
Is there a driver that I can use for this 7 segment 4 digit LCD? All I saw so far are drivers for dot matrix LCD screens.
Where can I find a wiring diagram for this controller and an MKR 1000?
Why is 4 mentioned twice on the board?
P.S. All technical data that I found about the TM1621D controller is in Mandarin or Cantonese (text as a picture). As I can read neither, I would appreciate a bit of insight. I would have tried google translate, but I don't have OCR on my acrobat.
