Extended On Time Timer Circuit
Half of a Motorola MG14538B dual precision retriggerable monostable multivibrator is utilized to create an extended on-time timer circuit. This type of circuit can function as a switch debouncer. Such circuits are commonly implemented in digital applications, where every bounce...
Automatic delay the start of operation of the circuit
After the power switch is activated, the motor does not start immediately but instead has a specified delay period. This setup allows the machine to perform automatic intermittent lubrication control. The circuit for the motor boot delay and intermittent operation...
Metal detector circuit diagram 5
The metal detector circuit comprises an oscillator and a sound-light alarm circuit. The oscillator circuit includes an inductor (L), a capacitor (C1), a sensor switch integrated circuit (IC1) that integrates the oscillator, detector, comparator circuit, and peripheral components. The sound-light...
Long-Interval Pulse Generator
A rectangular-wave pulse generator with an extremely long period can be constructed using only two components: a National Semiconductor LM3710 supervisor integrated circuit (IC) and a 100-nF capacitor to suppress noise spikes. This circuit leverages the watchdog and reset timers...
A Regularly Repeating Interval Timer circuit
This circuit features an adjustable output timer capable of re-triggering at regular intervals. The output duration can range from a fraction of a second to over half an hour, and it can be configured to recur at regular intervals from...
astable multivibrator
The capacitor C charges through resistors R1 and R2. When the voltage across the capacitor reaches 2/3 of the supply voltage, pin 6 detects this condition, and pin 7 is connected to ground (0V). The capacitor then discharges through resistor...
Pulse Generator Circuit
By utilizing a 556 dual timer, with IC1A functioning as a waveshaper and IC1B as a pulse generator, a pulse width range of 10:1 can be achieved. This circuit can be triggered using a sine wave.
The circuit operates on the...
Automatic Turn-Off Control For Automobiles Circuit
When the ignition switch is activated, relay K1 receives continuous power, allowing the headlights to be turned on. When the ignition is turned off, timer IC1 is activated, maintaining its power for a duration determined by resistor R1 and capacitor...
Stable Start-Stop Oscillator
Oscillators that generate a predetermined number of pulses are often required in applications such as video work. This oscillator starts 13 ms after the control signal goes high and stops immediately when the input signal goes low.
In electronic applications, pulse...
