Tm1637 4 Bits Digital Led Display Module For 7 Segment 0.36Inch Clock Red Anode Tube Four Serial Driver Board Pack

Description 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 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 lines for connecting the control interface of the module and the Cat duino development board; Experimental procedure: 1. Use 4 male to female lines 4-digit digital display module Connected to Cat duino, as shown in the following table and figure The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom's policies and EU Product Safety and Compliance laws.
