【Arduino】168种传感器模块系列实验(资料+代码+图形+仿真) 实验四十七:七段LED数码管模块Seven Segment Display 七段数码管为常用显示数字的电子元件。因为借由七个发光二极管以不同组合来显示数字,所以称为七段数码管,而七划旁的点为它的“第八划”。一般的七段数码管拥有八个发光二极管用以显示十进制0至9的数字...
因为采用环氧树脂灌封的全密封产品,外壳根本无法打开,强行用刀切割,随着面板的四分五裂,里面的电路和光导材料早已被破坏得面目全非了。 7.LED数码管除了常用的“8”字形数码管以外,较常见的还有图6所示的“±1”数字管、“N”形管和“米”字管等。其中,“±1”数字管能够显示 “+1”和“-1”,以及小数点“...
7 segments display:七盏LED组成的显示器,不同组合的亮灭可展示出阿拉伯数字0-9。 如此设置,就能用1和0(亮和灭)进行展示。 案例:倒数显示器 实体线路图 代码 // count down// define the LED digit patterns, from 0 - 9// 1 = LED on, 0 = LED off, in this order:// 74HC595 pin Q0,Q1,Q2...

Function lightSegments was reused from thesingle-digit 7-segment sketch: void lightSegments(byte number) { for (int i = 0; i < 7; i++) { int bit = bitRead(number, i); digitalWrite(segs[i], bit); } } Next week we will modify our project to use buttons to control each digit, ...
A sample code for a four-digit common anode display is shown below: #include <SevenSeg.h> SevenSeg disp(11,7,3,5,6,10,2); const int numOfDigits=4; int digitPins[numOfDigits]={12,9,8,13}; void setup() { disp.setDigitPins(numOfDigits, digitPins); } void loop() { disp.wri...
