High drive oscillator-flasher
The driver in the package is configured as a Schmitt trigger oscillator (A), utilizing resistors R1 and R2 to create hysteresis. The inverting feedback timing components consist of resistor R3 and capacitor C, while resistor R4 serves as the pull-down...
Metal detector circuit diagram 3
The metal detector consists of a probe oscillator, a reference oscillator, an audio amplifier, and various other components, as illustrated in the schematic. The probe oscillator is made up of transistors V1 and V2, a detection coil L1, a capacitor...
Ring Counter Circuit Working Principle with Animation and Video
Digital counters have various applications in electronic circuits. In digital electronics, counters are utilized in different situations. This article presents the concept of a ring counter circuit, which functions as a register counter. An animation and simulation video of the...
The Ecology of the Oscillator Transmitter
An oscillator-only transmitter appears to be the simplest way to access the radio airwaves; however, it presents several challenges as part of a transmitting and receiving station. The issue of finding an adequate crystal-controlled transmitter for newcomers wishing to operate...
cmos based vehicle anti theft alarm
This car alarm circuit includes Exit and Entry delays, an instant alarm zone, an intermittent siren output, and an automatic reset function. By incorporating external relays, it is possible to immobilize the vehicle and activate the lights.
The car alarm circuit...
Divide-By-N + 1/2 Circuit
This circuit divides the input signal by +1/2 instead of dividing by an integer. With the feedback connections as illustrated in the figure, the circuit effectively divides by 3.5. Point C ultimately determines when the input triggers the 74HC161 4-bit...
Digital alarm clock circuit diagram
U1 is the 3817 integrated circuit, capable of directly driving the display. It can show time in either 12-hour or 24-hour format, schedule alarm sounds, and automatically turn on the radio at specified times. The display utilizes the FND500 light-emitting...
