I'm trying to build a circuit to simulate a dice roll using a 555 in astable as it's heart. The output pulses are counted by a 4026 and then fed into a 4511 BCD to 7 segment decoder.
It works perfectly and counts from 0-9, but I cannot get it to reset at 6 and start from 1.
I have tried to take jam input 1 high and then take the preset enable pin high when the counter hits 7, but nothing happens. I did this by using a quad input AND gate. Inputs 1, 2 and 3 were the binary code for 7 (1110) and input 4 was the clock signal inverted, so it would only work when the clock was off. This did not work and it just got stuck on the number 7 without resetting.
Have any of you had experience with this type of circuit? What can I do?
