Learn how to make your Arduino appear to do multiple things at once (read sensors, control LEDs, handle user input, etc.) — using millis() and state machines instead.

Open a new sketch in your Arduino IDE. Copy and paste the following code. This script will count from 0 to 9999, proving that the display and wiring are working correctly.

While driving a single digit is simple, driving four digits simultaneously usually requires complex multiplexing and a mess of wiring. That changes today. In , we are going to explore the TM1637 4-Digit 7-Segment Display module. We will learn how to drastically reduce wiring complexity, display sensor data, and create our own custom scrolling text effects.
