Johnson Counter: How to use IC CD4033

Description

Comments

I wana make this circuit but also wana interface it with ir transmitter and receiver.. 

So if somebody will disturb the link it counts on seven segment...

 

Yes, I've seen the high sensitivity of CD4033. I had made a cordless voltage tester from this IC, a seven segment disp., resistors and filter capacitor. Not only was it indicating presence of emf around but was also able to count the steps I walked! I think some static charge from my slippers were making the clock/trigger at pin 1. amazing!

<p>How to dispaly numbers upto 25?How many ICs and displays are needed?What are the modifications to be done in this circuit for displaying numbers upto 25?</p>

You will need two ics to count from 1 to 25 ......And beyond... Up to 99
