I have a 555 astable creating a pulse to a 4017B to anotehr 4017B then to a 4026 for 7 seg display. This is a project for a sort of bleep test.
I have my circuit all working and counting on a breadboard but when i try to join resets together things go wrong.
The astable frequency is 1hz. This goes to a 4017B which counts 6 then resets. Output 6 is connected to clock input of another 4017B which has LEDs on it and LEDs light up on each 6 count after each other. The divide by 10 output is then connected to 4026B which powers the 7 segment display.
I need to make a single reset switch so all 3 chips reset at the same time which will act as a start and reset the LED to first output and 7 seg to zero.
Hope you can help. Any questions to s_collins@blueyonder.co.uk
