Clock MK153 AND K2634

Kits Timers and Clocks

HI! I AM TRYING TO CREATE IN THE SCHOOL A BIG CLOCK WITH THE KIT MK153 AND TWO KITS K26354 WITH TRIACKS AND OPTOCOUPLERS.
I CONECT DIRECTLY ON THE PIC TO THE CLOCK THE TIL111 OPTOCOUPLERS WITH MULTIPLE RESISTANCE BUT I CAN’T GET WORK
ANYONE HAVE ANY IDEA OF HOW TO DO IT?
GREETINGS

Please note that the MK153 uses a common anode display, so the pic outputs that drive the segments are driven low to light the segments.
When the segments are off, the pic outputs are high.

thanks for the note. If I have the common anode connected, connecting entries TIL111.
When you connect to each TIL111 and PIC with a small resistor 170ohm PIC does not work, when I connect a high resistance 2K TIL111 work but only 3 segments when the PIC connects 7 oscilate, the till111 haven a red LED in series.
I tried with variable resistors 1K and can not find the operating point or the PIC work or will not oscillate.
I thought about removing red leds.
any ideas?

Make sure the max. current per output does not exceed 20mA and make sure total port current does not exceed 100mA.
We would remove the leds too.
