I built acountdown timera couple of months ago using a two digit mechanical 7 segment display which was driven by 14 servos and an Arduino Mega. It came out quite well and a number of people suggested doubling up on the display to build a clock. The only problem was that the Arduino ...
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 ...

在这段时间里,你必须尽可能多地打汽缸。在第二次倒计时结束时,你的最终得分显示-所有这些都是使用7段显示。为了测试这两个7段数字,我们使用了下面的示例代码。我们所做的唯一修改是将引脚分配更改为50 (segmentLatch), 51 (segmentData)和52 (segmentClock)。
clock speeds as low as 1us and the chip still seems to respond well. Furthermore, from the (Chinese) datasheet it seems that you always have to perform three operation when communicating with the IC; set some configuration, set the address and send 1-4 digit data and set the display ...
Based on this information I created a TM1637 clock as shown on the photo above. I connected a TM1637 display to Arduino as follows: Arduino TM1637 display PIN #7 --- CLK PIN #8 --- DIO 3.3V --- VCC GND --- GND The code is ...
