A household light switch will work fine and is readily available at any hardware store.

Fairchild Semiconductor – datasheet pdf

This is necessary if the chip is to count freely. This final figure is the clock frequency in Hz. Lessons In Electric CircuitsVolume 4, chapter 4: You May Also Like: The buzzing you hear is the undivided clock frequency: It is important that the timing of the circuit be appropriate: Finally, we’ll try to find peaks in To experiment with this principle, connect your audio detector between output 0 pin 3 of the and ground, through a very small capacitor 0.

Finding Maximums in Noisy Data In this article, we’ll first study types of noise and then try to eliminate them by filtering the data. One way to combat this problem is to use a timing circuit to produce a single pulse for any number of input pulse signals received within a short amount of time.

When two metallic contacts are brought together rapidly as does happen inside most switches, there will be an elastic collision. Lessons In Electric CircuitsVolume 4, chapter If you have access to an oscilloscope, the audio detector is unnecessary.

Published under the terms and conditions of the Design Science License. However, you may notice some strange behavior: Your circuit may produce slightly different results.

Divide this number by 60 to obtain the number of timer cycles elapsed in each second my circuit: Quote of the day. The model integrated circuit is a CMOS counter with ten output terminals.

The buzzing you hear is the undivided clock frequency:. Actuate the switch again and note the counting behavior of the The audio detector will be used to assess signal frequency. Feel free to experiment with resistor and capacitor values on the timer to create different flash rates. Lessons In Electric CircuitsVolume 4, chapter 3: The WiCard This article explores the schematic design and basic features of a smart programmable wireless controller module I designed: If we are using the as a frequency divider, this means the output frequency will be a different factor of the clock frequency: See if you can produce octaves by dividing the original frequency by 2, then by 4, and then by 8 each descending octave represents one-half the previous frequency.

If you do not obtain a count that is exactly twice what you obtained before, it is because of error inherent to the method of counting cycles: In fact, knowing this mathematical relationship between clicks heard in the headphone and the clock frequency allows us to measure the clock frequency to a fair degree of precision.

Actuate the switch on and off, noting the action of the LEDs. Any single-pole, single-throw switch pm4017 adequate. This will increase the clock frequency driving the chip.

Significant Digits and Engineering Units Some rules of thumb for using significant digits and mitigating error propagation. With each off-to-on switch transition, pm4017 should increment once in its count.

Now, leaving one test probe of the audio detector connected to ground, take the other test probe the one with the coupling capacitor connected in series and connect it to pin 3 of the timer.

Counters such as the may be used as digital frequency dividers, to take a clock signal and produce a pulse occurring at some integer factor of the datsaheet frequency.
