thingiverse

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); //if (n&m) strip.SetPixelColor(i+p multiply 7,c); else strip.setPixelColor(i+p multiply 7, 0); if (n&m) strip.SetPixelColor(i+p * 7,c); else strip.setPixelColor(i+p * 7, 0); m=m*2; } } //For some reason, asterisks are not always shown in this editor. 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.
