Keyestudio EASY plug 4-Digit LED Display


Introduction

This is a 4-digit 0.36’’ Common Anode LED display module, a 12-pin display module with score points.
The driver chip used in the matrices is TM1637, using only two signal cables to make the microcontroller control the 4-digit LED display.
The four pins of LED display are GND、VCC、DIO、CLK. (GND is ground, VCC is for power supply, DIO is data IO pin, CLK is clock signal pin.)
The module pins are extended into Registered jack, so you can easily connect it to EASY Plug control board using a RJ11 cable.
Note: this module should be used together with EASY plug control board.

Parameters

  • Operating Voltage: DC5V
  • Operating Temperature Range: -40～+85℃
  • Property: ROHS


Technical Details

  • Dimensions: 50mm*23mm*18mm
  • Weight: 9g


Connect It Up

Connect the EASY Plug 4-Digit LED display to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

What You Should See

After uploading the code, you should see the 4-digit LED display show the number jumping.
On the left side, show 555; after one second, show 0125 on the right side; after one second, show 125; then after one second, the display brightness is 1, becoming rather darker. One second later, the display brightness is 7, becoming rather brighter.
After one second again, show the 12:89; then one second later, do not show the colon. After one second, the LED display is off; and one second later, start to repeat the display again.

Troubleshooting:

  • Compiling Fails ?

This happens sometimes, the most likely case is a library file not added. You should be sure all the libraries under the KS_EasyPulg are added to the libraries directory of Arduino-1.8.5. Shown below.

  • Program Not Uploading?

This happens sometimes, the most likely case is a confused Board and serial port, you should firstly select your proper board and port.
