    15 x IC 4017 Circuits and Projects

    Browse through a total of 15 IC 4017 Circuits and Projects.

    Automatic Bathroom Light Switch Here is a simple and low cost automatic bathroom light circuit. The light automatically turns on when the bathroom door is opened, and remains lit in the occupied state. When the door is opened again the lamp turns off after a very short delay. This automatic circuit saves energy and greatly assists your visitors, especially...
    4017 IC Datasheet 4017 IC is a CMOS counter/divider integrated circuit, actually a decada counter with 10 decode ouputs. It is 5 stage Johnson counters having 10 decoded outputs. Inputs include a clock, a reset, and a clock inhibit signal. Schmitt trigger action in the clock input circuit provides pulse shaping that allows unlimited clock input...
    Step Switch Selector As the name indicates, the step switch selector circuit is intended to choose one of up to four analogue switches, which it does with the aid of some less expensive components. It works off a regulated 5 volt dc supply and draws a current of few milliamperes. It may be used for a variety of applications, such as stepped volume...
    LED Scanner Circuit Here is a simple LED chaser simulating a scanner through the back and forth light effect. It used high bright White LEDs to give the chaser effect. The circuit uses an oscillator to produce fast pulses and a decade counter to drive the LEDs. IC1 is designed as an astable multivibrator to give continuous positive pulses to the...
    LED Chaser Circuit This is the circuit of a simple LED chaser. The LEDs lights one by one for a period of 1second and the cycle repeats giving the running light appearance. The circuit uses two ICs (one is 555) to drive the LEDs. IC1 (NE555) is the popular timer IC wired in the Astable Multivibrator mode. Resistors R1, VR1 and capacitor C1 act...
    Electronic Cricket Match Game This electronic cricket is a present for Kids. This simple battery powered circuit can be used to play Cricket Match with your friends. Each LED in the circuit indicates various status of the cricket match like Sixer, Run out, Catch etc. The Circuit uses two ICs ,one in the Astable mode and the second in the display driver...
    Network RJ45 Cable Tester Circuit This is a multifunction RJ45 network cable tester. It is the design of the network cable (RJ45) test, and telephone (RJ11). It is cheap and easy to use. It works for network, telephone, cable with RJ45 half “Registered Jack” plug immediately indicate whether a crossover network cable or straight, flashing a yellow or green...
    50 Hz Pulse Generator Circuit Here is a Crystal based pulse generator that gives 50Hz clock pulses from its output. This circuit can be used as the front end of circuits that require precision 50Hz pulses. The circuit uses two counter ICs CD4060 and CD 4017 to divide the basic frequency to generate 50 Hz pulses. CD4060 is the ripple free binary counter IC...
    Sensitive Clap Switch Circuit This is the circuit of a very sensitive clap switch. It switches ON/OFF a White LED or electrical appliances through claps. The circuit can sense the sound of claps from a distance of 1-2 meters. Condenser Mic picks up sound vibrations caused by the clap. These sound vibrations are given to the inverting input (pin2) of IC1....
    Police Car Lights with LEDs This circuit is used to simulate the police car lights by alternating flashing strobes seen on British police cars. The IC1a forms a square wave oscillator having adjustable frequency with VR1 to give the best effect. This square wave is buffered by IC1b and in turn drives the decade counter IC2. Outputs from the counter Q0/Q2...
