CD4017 CD4017BE CD-4017 4017 DIP-16 Pin Leads Dual In Package IC Breadboard Friendly IC

Description: CD4017 IC CD 4017 DIP 16 Pin IC

CD4017 CD4017BE CD-4017 4017 DIP-16 Pin Leads Dual In Package Sound Controlled Toggle Switch Using Decade Counter IC Breadboard Friendly IC

The IC CD4017 is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using Carry pin. This is commonly used for Led chasers and other logical output projects, so if you are looking for an sequential decoded counting IC that can count up to 10 then this IC will be your right choice

Working Explanation

The operating voltage of this circuit is 9 to 12V DC. The objective of the two transistors Q1 and Q2 is to amplify the audio signals coming from the electret microphone. The diodes rectify audio signals received from filter capacitor C3, turning the transistor Q3 switch ON. After the Q3 turns ON it provides positive pulses at the clock input pin of the IC (pin 14).

The IC CD4017 is wired as a toggle switch so when it receives positive pulses on the input pin its output is high and low at pin 2 and 3. When the microphone receives the first sound signal the relay and LED1 will activate till another sound signal is received which will deactivate the relay and LED1. The Q4 transistor drives the relay.
