Key Features:

✔ Adjustable Frequency Range – 1Hz to 500kHz (varies with RC components). ✔ Duty Cycle Control – Adjustable from 5% to 95% via potentiometer. ✔ NE555 Timer IC – Classic, reliable, and easy to configure. ✔ Wide Voltage Range – Works with 5V–15V DC (supports TTL/CMOS logic). ✔ Multiple Output Modes –

• Square wave (50% duty cycle default)

• PWM (variable pulse width) ✔ Breadboard-Friendly – Compact PCB with standard 0.1" pin spacing.

Applications:

• PWM Motor Speed Control – Drive DC motors, servos, or LEDs.

• Audio Tone Generation – Create alarms, beepers, or simple music.

• Clock Signal for Digital Circuits – Test counters, shift registers, or microcontrollers.

• DIY Function Generator – Basic signal source for lab use.

Wiring & Usage:

1. Power (VCC & GND) – Connect to 5V–15V DC.

2. Output (OUT) – Square wave signal (connect to oscilloscope or target circuit).

3. Adjust Frequency – Turn the frequency potentiometer.

4. Adjust Duty Cycle – Fine-tune with the duty cycle pot (if available).
