TM1637 LED Display Modul Für Arduino 7 Segment 4 Bits 0,36 Zoll Uhr ROTE Anode Digital rohr Vier Serielle Treiber Board
The module is a 12-pin display module with a 4-point common digital tube (0.36 inch) with a clock point. The driver chip is TM1637. It only needs 2 signal lines to enable the MCU to control the 4-bit 8- Segment digital tube. The module features are as follows: Display device is 4-digit yang red digital tube Digital tube 8-level grayscale adjustable Control interface level can be 5V or 3.3V 4 M2 screw positioning holes for easy installation Project Minimum value Typical value Maximum Unit Voltage 3.3 5 5.5 VDC Current (@5V) - 30 80 mA Size 42X24X12 Mm Weight 8 g Control interfaceA total of 4 pins (GND, VCC, DIO, CLK), GND is ground, VCC is the power supply, DIO is the data input and output pin, CLK is the clock signal pin; Digital Tube: 4-digit common anode with a 0.36-inch digital tube with a score point, highlighted in red; Positioning hole: 4 M2 screw positioning holes, the hole diameter is 2.2mm, which makes the module easy to install and position, and realize the module combination; Overview of the library routines: 1. ClockDisplay: Use the timer 1 of the MCU on the motherboard to time and let the 4-digit display display. 2. NumberFlow: 0~9, A, b, C, d, E, F and other 16 characters flow from right to left. 3. StopWatch: Use the timer 1 of the MCU on the motherboard to time, and use the button to realize the stopwatch function. Experiment equipment: An Ard uino compatible motherboard Cat duino (not familiar with open source hardware can be understood as the Atmega328P microcontroller development board) and a mini USB cable; 1 4-digit digital tube display module; 4 male to female DuPont lines for connecting the control interface of the module and the Cat duino development board; Experimental procedure: 1. Use 4 male to female DuPont lines 4-digit digital display module Connected to Cat duino, as sho
