Hello guys,
Im building a Counter using a 4510 Decade Counter to count from 0 to 50 in 2 7 segments. Now the problem that Im having is that I want to be able to perform the counts manually and automatically. I built 2 555 circuits, one astable that gives me a 1 sec clock and the other monostable so when I push a button, it produces me a clock to get the counter up or down. Im using a 2 position switch with 3 pins. At the ends I have the 555s and in the middle of the switch i have the cable that goes into the 4510 circuit. Works fine, but here is the "problem" If I have a number in display and switch from manual to automatic or the other way, if the movement of the switch its slow, the counters go crazy. Is there a way to fix this?
I tried to put both circuits to the same pin in the counter but does work, it does nothing in the counting. I also put 2 diodes at the end of each 555 so one signal doesnt bounce back to the other 555, but the 4510 goes wild also.
Any other Ideas?
Best Regards
