SUMMARY

The discussion focuses on integrating a 4017 decade counter with a 555 monostable multivibrator to control multiple devices sequentially. The user successfully built a 555 chip-based monostable multivibrator with a 5-second output time and seeks to use the 4017 to activate different devices with each trigger. A solution is proposed involving a toggle flip-flop to maintain device activation after the 4017 advances, ensuring that a device remains on until the counter completes a full cycle of 10 pulses.

PREREQUISITES
  • Understanding of 555 monostable multivibrator operation
  • Familiarity with 4017 decade counter functionality
  • Knowledge of toggle flip-flop circuits
  • Basic electronics and circuit design skills
NEXT STEPS
  • Research the operation and applications of the 555 monostable multivibrator
  • Study the 4017 decade counter's output behavior and connections
  • Learn about toggle flip-flops and their role in circuit design
  • Explore practical examples of sequential device control using counters
USEFUL FOR

Electronics hobbyists, circuit designers, and engineers interested in sequential control systems and timer-based device activation.

Hi!

I just finished building a 555 chip based monostable multivibrator with a output time of about 5 seconds after reception of the trigger.

Can I couple a 4017 decade counter IC to the output pin of the 555 so that I can use it to operate different devices one after the other depending on the trigger I keep giving after every 5 seconds?

I tried to look this question up on the net but the answer eludes me.

Any help would be much appreciated!

Sorry I meant to say that I would like to keep a device turned on even after the 5 second clock pulse ends. The next device turns 'on' only when the next trigger is given

If a device is to stay on after the decade counter advances to the next output, how will you turn your device off. One way would be to connect a toggle flip flop to the output which would cause the device to turn off after the 4017 cycles around to the same output after 10 input pulses. Of course you would have to cycle through another 10 pulses to turn it on again.
