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 ...
void displayDigit(unsigned char digit) { //定义一个数组表:不同数字的abcdefgh各段的取值 unsigned char abcdefgh[][8] = { {1,1,1,1,1,1,0,0}, //0 {0,1,1,0,0,0,0,0}, //1 {1,1,0,1,1,0,1,0}, //2 {1,1,1,1,0,0,1,0}, //3 {0,1,1,0,0,1,1,0}, //...
The Arduino is a popular open-source electronics platform that can be used to control various devices. One of the common devices used with Arduino is the LCD display. The LCD module can be interfaced with the Arduino to display text, numbers, and other i
