WS2812B 7 segment display

7-Segment frame and transparant segments. Size 27 x 47 mm. WS2812B LED display behind the segments needs only one control wire for 28 segments.

Arduino : Segment arranged a-g clockwise. Adafruit library.

byte tab[]={0x3f,0x06,0b1011011,0b1001111,0b1100110,0b1101101,0b1111101,0x07,0x7f,0b1101111}; //shapes

void num( byte n, byte p, unsigned long c) { // digit n, position p, color c

byte m=1; n= tab[n];

for(byte i=0; i<7; i++)

{

//c=random(0xffff);  //random color of each segment

//if (n&m) strip.SetPixelColor(i+p * 7,c); else strip.setPixelColor(i+p * 7, 0);

if (n&m) strip.SetPixelColor(i+p*7,c); else strip.setPixelColor(i+p*7, 0);

m=m*2; } }

//Asterisks are not always shown in some editors. If you see p 7, it should be

p-asterisk-7 ( p*7, multiplication). When you copy-paste, please check and correct this.

//For random segment colors, uncomment random instruction.
