TM1638 8-Bit Digital LED Tube with 8 Push Buttons LED Display Module for Arduino

Description: Descriptions: Function IntroductionIncluding the following resources:1. 8 buttons2. 8 LEDs3. 8-bit digital tubeThe chip used in this module is TM1638, which combines the three common peripheral circuits of microcontrollers mentioned above. The biggest feature is that it only needs to occupy three IO ports of the microcontroller to drive. Scanning display and key scanning do not require microcontroller intervention, only reading and writing relevant registers to send display data or detect buttons, saving MCU resources. Purchase this module to provide an instance program.Imagine, how many IO ports do we need to use a microcontroller to connect 8 LEDs, 8-bit digital tubes, and 8 buttons externally? It's far more than 3 IO ports, but this module can be used to achieve this. Through practical application, the buttons are sensitive and the display effect is good.Wiring method:VCC GND is connected to a 5V power supply, and STB CLK DIO is connected to the microcontroller IO port.
