7-segment dynamic indication with 3 digit 7 segment display .You can set high frequency to make indication without blinkings. Set your values by using binary code on the right. I didn't use complete 7-segment indicators because they are havn't common pins. So segments are from left to right (a...g). Every string is a next digit with own value. The NE555 is clock generator. Every new pulse switching counter to the new position.
