I am making an electronic dice for a school project. I want to use an a stable --%26gt; 4026 --%26gt; 7 segmant display combination. I only need it to count up to 6. I know you can reset a 4017 at 6 but im not sure how to with a 4026 - should i just use a PIC?How to reset a 4026 connected to a seven segmant display at 6.?

Thing is, while it has a reset pin,
how do you detect when it should reset (value = 7)
You could put a big And/NAND gate arrangement to detect the segments for 7 (the OFF and the ON ones) and hit the reset pin when it does.
Just a thoughtHow to reset a 4026 connected to a seven segmant display at 6.?
Since you don't have acces to the BCD outputs you must use a 3 inputs NAND gate to trigger the reset using the segments of the digit(find out which are the most important segments for 6).
Also be ware,because you are trying to make a dice(1 to 6) but 4026 start to count from 0 after reset so it isn't what you are looking for!
A better way will be a MC 4192(up/down preset counter) and a 74LS47 as driver for the 7 segments digit.Instead of using the reset function use the preset function of the 4192 to preset ';1'; and make the ';reset'; by activating the preset!!!
Good luck!!!
