2 LED CMOS Flasher
The two LED CMOS flasher circuit utilizes the CD4069 integrated circuit, which contains six inverters, to create a multivibrator configuration. This circuit is designed to flash two LEDs alternately, providing a visual indication of the oscillation created by the inverter gates.
In this configuration, two of the six inverters are employed to form a basic astable multivibrator. The circuit operates by charging and discharging capacitors, which control the timing of the LED flashes. The LEDs are connected to the output of the inverters, allowing them to turn on and off in succession.
The key components of the circuit include:
1. **CD4069 IC**: This is a hex inverter that provides the necessary logic levels for the multivibrator operation.
2. **Resistors**: Used to limit current to the LEDs and to set the charging and discharging time constants for the capacitors.
3. **Capacitors**: These components are crucial for determining the frequency of the flashing LEDs by controlling the timing intervals.
4. **LEDs**: Light Emitting Diodes that visually indicate the output states of the circuit.
The circuit is powered by a DC voltage source, typically ranging from 3V to 15V, depending on the specifications of the LEDs and the CD4069. The values of the resistors and capacitors can be adjusted to change the frequency of the flashing LEDs, allowing for customization of the visual output.
Overall, this simple yet effective circuit serves as an excellent introduction to basic CMOS technology and multivibrator design, demonstrating fundamental principles of electronics in a practical application.Two LED CMOS Flasher Circuit Diagram This is a simple 2 led cmos robot ( flasher, multivibrator ) circuit using CD4069 six inverter.. 🔗 External reference
